  • Page 28: Digital Outputs

    3.3.2 Digital Outputs The OP7200 has eight digital outputs, OUT0–OUT7, which are individually configurable with the software function calls as sinking digoutConfig digoutTriStateConfig (up to 350 mA per channel) or as sourcing (up to 250 mA per channel). Figure 9 shows a wiring diagram for using the digital outputs in a sinking or a souring configuration.
  • Page 29 boards can be made to order in volume with the digital outputs pulled up to Vcc or +K, or pulled down to GND. Contact your authorized Rabbit Semiconductor distributor or your Rabbit Semiconductor Sales Representative for more information. +K is an externally supplied voltage of 9–40 V DC used primarily in combination with current sourcing outputs, and should be capable of delivering up to 2 A.

  • Page 30: Analog Features (Op7200 Only)

    3.4 Analog Features (OP7200 only) The single A/D converter used in the OP7200 (the OP7210 does not have analog or touch- screen capabilities) has a resolution of 11 bits (single-ended mode) or 12 bits (differential mode). There are eight channels of A/D conversion, and the OP7200 also has provision for up to four digital inputs.
  • Page 31 The A/D converter chip can make either single-ended or differential measurements depending on the value of the parameter in the software function call. Adjacent opmode A/D converter inputs are paired to make differential measurements. The default setup for the OP7200 is to measure only positive voltages for the ranges listed in Table 2. Table 2.
  • Page 32 The A/D converter chip can only accept positive voltages. When the 0 Ω resistor shown in Figure 11 ties the A/D attenuator circuit to analog ground, both differential inputs must be ref- erenced to analog ground, and both inputs must be positive with respect to analog ground. If a device such as a battery is con- nected across two channels for a 180 kW...

  • Page 33: Analog Current Measurements

    The input circuit of the OP7200 was designed to use the differential mode in a unique way to support measuring voltages in an equal range above and below ground. This method also requires you to move the 0 Ω jumper (see Figure 11) on the header associated with the A/D converter inputs (JP4, JP5, JP6, or JP7) from analog ground to the 2.048 V reference voltage.

  • Page 34: Calibrating The A/D Converter Chip

    3.4.3 Calibrating the A/D Converter Chip Manufacturing tolerances for resistors, bias currents, offset voltages, gain, and the like introduce errors into the A/D conversions. Ideally there would be a one-to-one straight- line relationship between the input voltage and the output of the A/D converter, and a graph of such a line would have a slope of 1 and would pass through the (0,0) coordinate.
  • Page 35 To get the best results form the A/D converter, it is necessary to calibrate each mode for each of its gains. The following table provides a grid for each possible set of calibration constants. Mode Single-Ended Differential Gain Code For the single-ended mode there are calibration constants for each channel and for each of its gains, for a total of 64 sets of calibration constants.
  • Page 36 calibration is performed and the jumper is subsequently moved, the corresponding input(s) must be recalibrated. The calibration table only holds calibration constants based on mode, channel, and gain. Other factors affecting the calibration must be taken into account by calibrating using the same mode and gain setup as in the intended use. It is not necessary to fill out the entire calibration table.

  • Page 37: Touchscreen

    3.4.4 Touchscreen The OP7200 analog touchscreen provides a high-resolution matrix of 4096 × 4096 elements. The touchscreen is mounted to the front of and is the same size as the LCD mod- ule. A four-conductor flex cable connects the touchscreen to the OP7200 at connector J13. The inputs from the touchscreen are protected from ESD by ferrite beads, capacitors, and shunt diodes.

  • Page 38: A/D Converter Reference Voltage (+V)

    3.4.6 A/D Converter Reference Voltage (+V) A reference voltage of 2.048 V is generated by the A/D converter chip. The reference volt- age is used by the touchscreen controller chip, and may also be used to bias the input attenuator circuits when bipolar inputs are to be measured. As shown in Figure 14, the factory default is for a surface-mounted 0 Ω...

  • Page 40: Rs-232

    3.5.1 RS-232 The OP7200 RS-232 serial communication is supported by an RS-232 transceiver. This transceiver provides the voltage output, slew rate, and input voltage immunity required to meet the RS-232 serial communication protocol. Basically, the chip translates the Rabbit 2000’s CMOS/TTL signals to RS-232 signal levels. Note that the polarity is reversed in an RS-232 circuit so that a +5 V output becomes approximately -10 V and 0 V is output as +10 V.
  • Page 41 The OP7200 comes with a 220 Ω termination resistor and two 681 Ω bias resistors installed and enabled with jumpers across pins 1–2 and 4–6 on header J8, as shown in Figure 16. 485+ bias 681 W termi- 220 W nation R159 MSTR...

  • Page 42: Rabbitnet Port

    3.5.3 RabbitNet Port The RJ-45 jack labeled RabbitNet is a serial I/O expansion port for use with RabbitNet I/O cards. The RabbitNet jack does not support Ethernet connections. There is also no provision for the OP7200 to supply power to any RabbitNet peripheral cards. When you are using the OP7200 in a RabbitNet network, Serial Port B is configured as a clocked serial port and the RS-485 chip drives the RabbitNet port—the OP7200 then cannot be used for RS-485 serial communication.

    D. R PPENDIX ABBIT D.1 General RabbitNet Description RabbitNet is a high-speed synchronous protocol developed by Rabbit Semiconductor to connect peripheral cards to a master and to allow them to communicate with each other. D.1.1 RabbitNet Connections All RabbitNet connections are made point to point. A RabbitNet master port can only be connected directly to a peripheral card, and the number of peripheral cards is limited by the number of available RabbitNet ports on the master.

  • Page 158: Rabbitnet Peripheral Cards

    Use a straight-through Ethernet cable to connect the master to slave peripheral cards, unless you are using a device such as the OP7200 that could be used either as a master or a slave. In this case you would use a crossover cable to connect an OP7200 that is being used as a slave (note that Dynamic C does not support the operation of the OP7200 as a slave at the present time).

  • Page 159: Physical Implementation

    D.2 Physical Implementation There are four signaling functions associated with a RabbitNet connection. From the mas- ter’s point of view, the transmit function carries information and commands to the periph- eral board. The receive function is used to read back information sent to the master by the peripheral board.
