3. Inputs The PHD has digital, frequency, and analog inputs. Damage to equipment! Do not connect inputs directly to unprotected inductive loads such as solenoids or relay coils, as these can produce high voltage spikes that may damage the PHD. If an inductive load must be connected to an input, use a protective diode or transorb. 3.1. PHD28 Inputs The PHD28 has up to 7 analog inputs: GPIO1 through GPIO7 • Analog inputs are typically used to read electrical signals that span a voltage range. Depending on the PHD model, certain inputs can also be configured as inputs for the wake-up functionality. On the PHD28, Touch, CAN1, and GPIO 1 through GPIO7 can be configured for wake-up functionality. Additionally, certain inputs can be configured as low power outputs. See section 3.4 for more information. The different configurations are done in software. 3.2. PHD50 Inputs The PHD50 has up to 8 analog inputs: GPIO1 through GPIO8 • Analog inputs are typically used to read electrical signals that span a voltage range. Depending on the PHD model, certain inputs can also be configured as inputs for the wake-up functionality. On the PHD50 the wake options are, Touch, CAN and GPIO1 through GPIO8. Wake on GPIO9 and GPIO10 is allowed on the PHD50 only if an encoder is not selected, or the FIN input is not selected. On the PHD50 PF, with the extended wake/sleep functionality, only GPIO1 can be used as a wake signal. Additionally, certain inputs can be configured as low power outputs. See section 3.4 for more information. The different configurations are done in software.
3.3. PHD70 Inputs The PHD70 does not support analog inputs. The PHD70 has up to 8 digital inputs: GPIO1 through GPIO8 • Digital inputs are typically used to read electrical signals from switches. Depending on the PHD model, certain inputs can also be configured as inputs for the wake-up functionality. On the PHD70 the wake options are, CAN, Touch and GPIO1 through GPIO8 can be used as wake signals. Wake on GPIO9 and 10 is allowed on the PHD70 only if an encoder is not selected. Note: on the PHD70, wake on CAN will wake on CAN traffic on either CAN1 or CAN2. Additionally, certain inputs can be configured as low power outputs. See section 3.4 for more information. The different configurations are done in software. The PHD70 has 1 quadrature encoder input on GPIO9 and GPIO10 . The encoder inputs are provided for the uses of a rotary encoder as an input device. The encoder states must change 4 times per detent in the shaft rotation to be recognized by the PHD70, see chart below for the required waveform. Figure 3.2. X2 encoder waveform X4 encoder waveform 3.3.1. PHD28/PHD50 analog input capabilities The PHD28 and PHD50 have analog inputs. These inputs are also configurable as digital inputs by programming the voltage threshold in the Lua scripting tool to make them digital. Analog inputs are useful for reading potentiometers and Hall Effect signals. The following table provides specifications for the analog inputs: Analog input specifications Item Unit Input voltage range...

3.3.1.1. Analog input connections Analog inputs are susceptible to system noise, which can affect the accuracy of the signal. Signal accuracy can also be affected by ground level shift, which can cause inputs to activate when they shouldn’t. System noise To prevent noise pickup on the sensors, • Use the shortest possible wires when connecting analog inputs to sensors. The following diagram shows connect an analog input to reduce system noise: Internal to product Sensor +5 Vdc Sensor Supply Analog Input Sensor Ground Figure 3.3. Analog input system noise reduction Ground level shift To reduce ground level shift: 1. Dedicate one of the system ground inputs (GND) to sensors that have dedicated ground wires and connect all sensor grounds to this system ground input. 2. Splice the other system ground inputs together in the vehicle harness (close to the connector) to provide a better ground for the noisier low-side outputs and digital circuits. 3. Position the sensor’s ground connection near the system ground connections to ensure that the signal remains within the digital activation range of the input. Note: The system ground inputs are rated for low-current signals, which ensures the sensor’s ground is very close in voltage potential to the system ground.

Analog input ground shift connection for sensors that have dedicated ground wires 3.3.2. PHD70 digital input capabilities The PHD28 and PHD50 displays have analog inputs, but they can be configured as digital inputs by programming the voltage threshold in the Lua scripting tool to make them digital. • The PHD70 has up to 10 traditional active high digital inputs. • The PHD70 digital inputs can also be configured as low power digital outputs.

• The power provided to the digital switch connected to the input must be provided through a fuse in the wire harness. A typical active-high digital input connection is shown below: Internal to product Application Switch Active High Digital Input Battery Figure 3.5. Active-high digital input 3.3.3. PHD50 frequency input capabilities The PHD50 has 1 frequency input on GPIO9 that can be configured as FIN or GPIO. The frequency input is ideal for use with hall-effect type sensors.

DC-coupled frequency inputs are more susceptible to system noise than digital inputs. To reduce system noise: • Connect DC-coupled frequency inputs to sensors that produce signals with no DC offset. • Use the shortest possible wires when connecting DC-coupled frequency inputs to sensors to prevent noise pickup on the sensors. Ground Level Shift Ground level shift affects the accuracy of DC-coupled frequency inputs. Ground level shift refers to the difference between the system ground input (GND) voltage, and the sensor ground voltage. To reduce ground level shift: • If there are more than 1 GND pins in the system, dedicate one of them to sensors that have ground wires, and connect all sensor grounds to that system ground pin. • Splice the other system ground inputs together in the vehicle harness (close to the connector), to provide a better ground for the noisier low-side outputs and digital circuits. • Ensure the sensor’s ground connection is close to the system ground connections. This will help ensure the signal remains within the digital activation range of the input. Note: The PHD system ground inputs are rated for low-current signals, which ensures the sensor’s ground is very close in voltage potential to the system ground. Note: Sensors that don’t have a dedicated ground wire are typically grounded to the vehicle chassis through the sensor’s body. The following shows a typical DC-coupled frequency input connection: Internal to product Sensor Voltage Hall Effect Sensor DC Coupled Frequency Input Sensor Ground Figure 3.6. DC-coupled frequency input installation connections 3.4.
outputs are suitable for driving LEDs and other small loads. 3.4.1. Low power, high-side output capabilities The following table provides specifications for the inputs when used as low power outputs. Low power output specifications Item Unit Operational voltage range Output resistance w.r.t. GND (output off) 26.2 kΩ Output voltage Output current Leakage current (output off) µA Output pin capacitance 3.4.1.1. Low power, high-side output connections You must be aware of the following when connecting the low power, high-side outputs: • the outputs are connected to the internal +5 Vdc supply through a pull-up resistor. Each output is de- rated to 4.3 V. Maximum load on each output is 358 mA. • the outputs can provide power to LED or other small loads in a vehicle. When connecting the low power, high-side outputs, ensure you follow these best practices: • the outputs should not be connected to loads that will draw currents greater than the maximum current. • The grounds for the loads should be connected physically close to the PHD power grounds.
4. Outputs There are 2 types of outputs on the PHD family of displays. • Low-side outputs • Sensor supply outputs 4.1. PHD28/PHD50/PHD70 Low-side outputs The PHD family has two low-side outputs, with the following pin assignments: OUTPUT1 through OUTPUT2 • 4.1.1.

4.1.1.1. Low-side output connections When connecting low-side outputs, note that • low-side outputs are connected to a common internal ground point that is connected to the battery ground (GND). • low-side outputs provide switched ground to any load type in a vehicle. • low-side outputs can sink up to 0.5 A. When connecting a load to a low-side output, ensure that the load will not drive currents greater than the maximum specified peak current or the maximum specified continuous current. The following shows a typical low-side output connection: Internal to product Application Low-Side Load Output Battery Figure 4.1. Low-side outputs with current sense installation connections 4.2. Sensor and regulated supply outputs The PHD has 2 types of sensor supply pins, labeled USB_VBUS, P5V0 and P12V0 dedicated to providing power to external sensors and devices. • 5V USB or sensor supply • 12V regulated supply The PHD28 has 1 of each type of supply: • USB_VBUS / P5V0 is a 5V supply •...

In low voltage conditions the voltage drop can result in the sensor supply going below minimum range. PHD User Guide...
5. Power The PHD family is powered by a direct battery connection. The display is turned on by applying power to one of the wake-up inputs or a CAN message, depending on configuration in software. The direct battery input is protected against vehicle transients such as load dump and inductive load switching, etc. It is also protected against reverse battery voltage of -33 V through the use of a high-current path that will cause an external fuse to blow. The PHD operates in a 12 V or 24 V system and can operate from 9 V up to 32 V with over-voltage protection at 33 V. The following table provides specifications for the PHD power: Parameter Unit Input voltage for normal operation Minimum cranking voltage (see note 1) Over-voltage protection Reverse battery protection (see note 2) Recommended External Fuse Maximum continuous current (see note 3) VBATT=13.8 V 0.44 1.781 VBATT=27.0 V 0.22 0.93 Rating of External Fuse Not 1e: The unit will operate below 9 V, down to 7 V, but the LCD back-lighting may be dim. Not 2e: A reverse battery condition causes an external fuse to blow. Not 3e: This is the maximum expected value, not including the additional draw of the outputs, or the regulated 5VDC and 12VDC supplies. PHD User Guide...
6. Communication The types of communication available to the PHD family are Controller Area Network (CAN) communication and USB host. 6.1. Controller area network The PHD28 and PHD50 have 1 Controller Area Network (CAN) communication port available. The PHD70 has 2 CAN communication ports available. The PHD family hardware provides controller area network (CAN) communication according to the SAE J1939 specification, making the PHD compatible with any CAN-based protocol through software. CAN communication is used to communicate the status of multiple modules that are connected to each other in the same network. 6.1.1. CAN Capabilities The CAN communicates information at a selectable rate from 125 kbps to 1000 kbps. Lack of regular CAN communication is an indication that there is either a problem with a module in the network, or a problem with the CAN bus. CAN communication provides a feature called Wake on CAN, which is a way to provide power control to the PHD. Wake on CAN provides a low-current sleep mode that turns on the PHD when a CAN message is received by the module. It is not possible to filter messages that are used to turn on the PHD using Wake on CAN. For this reason, any message will turn on the PHD. The application software must be written to determine how the PHD will behave when it is turned on. The following table provides specifications for the CAN: CAN Specifications Item UNIT Baud rate limitations (hardware) 1000 kbps Baud rate limitations (software) 1000 kbps Wake on CAN current draw Termination resistor Ω...

To implement the internal CAN1 internal termination resistor, the CAN_TERM pin should be wired as shown. Figure 6.1. PHD CAN_TERM wiring Note: Note this is not available on CAN2 of the PHD70. The following lists the elements that are required for a J1939 CAN connection: • CAN Cable: A shielded twisted-pair cable should be used when connecting multiple modules to the CAN bus. The cable for the J1939 CAN bus has three wires: CAN High, CAN Low, and CAN Shield (which connect to the corresponding CAN_HIGH, CAN_LOW, and CAN_SHIELD pins on the connector). When a module does not have a CAN_SHIELD pin, the CAN Shield should be connected to an available ground terminal attached to the negative battery. The CAN cable must have an impedance of 120 Ω. • The CAN cable is very susceptible to system noise; therefore, CAN shield must be connected as follows: Connect CAN Shield to the point of least electrical noise on the CAN bus. Connect CAN Shield as close to the center of the CAN bus as possible. Use the lowest impedance connection possible. Note: Ground loops can damage electronic modules. The CAN Shield can only be grounded to one point on the network. If grounded to multiple points, a ground loop may occur. • CAN Connectors: Industry-approved CAN connectors are manufactured by ITT Cannon and Deutsch, and come in either T or Y configurations. • CAN Harness: The CAN harness is the main backbone cable that is used to connect the CAN network. This cable cannot be longer than 40 meters and must have a 120 Ω terminating resistor at each end. The 120 Ω terminating resistors eliminate bus reflections and ensure proper idle-state voltage levels. • CAN Stubs: The CAN stubs cannot be longer than 1 meter, and each stub should vary in length to eliminate bus reflections and ensure proper idle state voltage levels. • Max Number of Modules in a System: The CAN bus can handle a maximum of 30 modules in a system at one time.

J1939 CAN connection 6.2. USB The PHD family supports one USB port capable of full speed USB 2.0. The USB port is configured as Host or Device based on settings in software. The USB port allows you to connect temporarily to the unit for the purpose of updating code or configuring the unit. The following table provides specifications for the USB port: USB Device Specifications Item Unit Communication speed - Full Speed Mbps Capacitance of I/O to ground...
7. HMI (Human Machine Interface) The PHD family has an easy to use graphical user interface consisting of a color LCD and touchscreen with the option of adding a keypad. 7.1. Ambient light sensor The PHD70 display, if enabled, will automatically adjust the display’s backlight, based on the amount of ambient light. The ambient light is sensed and measured via the sensor opening on the glass face. At 1000 lux or greater the backlight is at full brightness when the auto adjustment is enabled. 7.2. Touchscreen The display uses a capacitive touchscreen and the host CPU controls the power and reset with the touchscreen providing an interrupt back to the host. If the touchscreen interface is required as a wakeup source, then the host must leave power on the interface and the TP must not be in reset when the host goes to sleep. There is a series of commands that must be written to the touchscreen controller to ensure that it’s in its lowest power mode. The interrupt for wakeup will be driven to the host CPU as well as the power CPU. 7.3. Keypad The PHD family of displays does not have an integral keypad. The PHD will support an external keypad (e.g. four button interface, five button interface, 10+ key grid keypad) via the GPIO and any or all of the lines can act as a wakeup source. 7.4. Buzzer The PHD units themselves do not house a buzzer. A regulated 12Vdc supply is provided from the pins of the main connectors and this can be used to power a buzzer. Note that this interface is limited to 500mA. To drive the other leg of an external buzzer, low-side output 1 or 2 can drive either a steady state low or a PWM output to drive a buzzer. This low-side output is also capable of sinking 500mA. 7.5. Video The PHD50 and PHD70 support analog video cameras. • PHD50 has 1 video input • PHD70 has 2 video inputs The PHD50 supports one D1 resolution PAL/NTSC input.
7.5.1. Video input capabilities The following table provides specifications for the video inputs. Video Input Specifications Parameters Unit Input voltage range -5.6 Input resistance Ω Capacitance at pin 7.6. Real Time Clock The Standard PHD70 (not the reduced memory version) supports a Real Time Clock (RTC). The RTC values can be set and read using the corresponding API calls outlined in the PHD API Manual. The RTC values are maintained during power down by a super-capacitor mounted in the PHD70. The following table provides specifications for the RTC. Real Time Clock Specifications Parameters Unit Setting retention time PHD User Guide...
8. Serial Ethernet Recovery Flexcan (SERF) Board and Development Harness The SERF Development Board for the PHD is intended as a development tool to simulate inputs and outputs when attached to a PHD display. 8.1. SERF Overview The SERF Development Board allows the GPIO, CAN Bus, video and RS232 inputs and outputs to be easily accessed without having to make a custom wire harness or build a special I/O board for each development project. The SERF Development Board should be used in conjunction with the available Power and I/O cables for PHD displays. See Catalog MSG33-5024-US, PHD Accessories, for more information. Figure 8.1.

8.2.3. PHD development harness If simulating the I/O isn’t required, the PHD Development Harness is a simpler, more robust option for application development. The cable contains Power, CAN, video, USB and serial connections for application development, but all contained in the harness itself. See Catalog MSG33-5024-US, PHD Accessories, for more information. Figure 8.5. PHD development harness PWR/GND Development Harness Inputs and Outputs include: • 12VDC Power Output and Ground connections • 12VDC/24VDC Power Supply and Ground • RS232 Communication (UART) • CAN Bus 1 and 2 • USB Type A Connection • Video 1 and 2 • Recovery Switch* *Keep the Recovery Switch in neutral or USB position for normal boot mode. The RCY position is for factory use only. Leave in Neutral to program PHD50 and in the USB position to program the PHD28 and PHD70. Figure 8.6. Recovery switch PHD User Guide...
8.2.4. DB9 Pinout Reference Both the CAN connector on the SERF board and the RS232 connectors on either interface use standard DB9 connectors for ease of use. Most of the common adapters for either RS232 or CAN that are required to interface with a PC offer this connection type. The following table shows the pin outs for each of the DB9 connectors: RS232 Description Description No connect No connect CAN L TX (transmit) No connect RX (receive) No connect No connect Shield GND (signal ground) No connect No connect CAN H No connect No connect No connect No Connect No connect RS232 settings: Baud rate 115200, 8 data bits, no parity, 1 stop bit.

9. Mounting the PHD To mount the PHD into a vehicle mounting panel, 1. Install the PHD from the front. 2. Ensure that: • the PHD is oriented to the operator’s viewing angle • the wire harness connects easily to the connectors and that the bend radius is adequate • the harness is shielded from harsh impact 3. Secure the PHD using 4 screws or metal spring clips. 4. Install the bezel, typically provided by the customer (Parker does sell a snap-on cosmetic bezel as an optional accessory). The PHD may also be mounted from the rear of the panel without a bezel for a flush appearance using insert studs and nuts. Drawings and other documents may be found at www.parker.com/ecd or contact your Parker representative. 9.1. Dimensions The dimensions for each of the PHD family of displays is provided below. 9.1.1.
