    OP7100 Subsystems Overview The OP7100 consists of several subsystems, including a computing module, serial communication channels, lquid crystal display (LCD), a buzzer, and a keypad interface. Figure 3-1 provides a block diagram of the OP7100. Digital Z180 SRAM Flash1 Flash2 ’691...

  • Page 25: Power Management

    Power Management The OP7100 was designed to operate from a 12 V to 30 V DC source, and consumes about 4.5 W with the backlight on, 1.5 W with the backlight off. To allow for a surge current when the OP7100 is first turned on, the power supply used must be able to handle at least four times this power (for example, 800 mA at 24 V).

    R34, between the comparator input and output pins. R34 can be found on the 175-0196 and the 175-0211 versions of the OP7100. The hysteresis prevents the comparator from switching rapidly—and therefore generating multiple interrupts—when the input voltage is falling slowly.

    The 240 × 320 ¼ VGA LCD supports both graphics and text. Automatic contrast control is built in so that the contrast, once set, does not drift as the OP7100 warms up or is moved. Figure 3-4 provides a block diagram of the LCD control and RAM circuits.

  • Page 32: Coordinate Systems

    LCD Controller Chip The LCD controller chip provides support for the LCD module. The controller chip is attached to the data bus on the OP7100, and is mapped to the I/O address space. This interface is composed of eight data bits, one address line, and three control lines (RD, WR, and 1335-CS).

    Keypad Interface The OP7100 has a touchscreen, which is connected to the circuit board at header J5. Header J6 is available for a customer-supplied keypad for the OP7110. Table 3-1 lists the pinouts for headers J5 and J6. The pinout for header J5 is identical to the pinout for header J6.

    R2IN 232A Figure 3-14. Serial Channels The factory default configuration for the OP7100 is for one 5-wire RS-232 port (with RTS and CTS) and one half-duplex RS-485 port. An RS-485 channel can provide half-duplex asynchronous communication over twisted-pair wires for distances up to 3 km. Two other configurations, shown in Figure 3-14, are one 3-wire RS-232/one RS-485, and two 3-wire RS-232.

    The availability of DCIN on pin 9 of header J7 allows a DC power supply to be made available to the device being connected to the OP7100. Rabbit Semiconductor has RS-232 support libraries for Z180 Ports 0 and 1. The following functional support for serial communication is included. •...

  • Page 39: Cts/Rts Control

    CTS/RTS Control The Z180’s hardware constrains its Port 0 to have the CTS (clear to send) pulled low by the RS-232 device to which it is talking. The OP7100 does not support CTS for the Z180’s Port 1. Modem Communication Modems and telephone lines facilitate RS-232 communication across great distances.

  • Page 40: Rs-485 Communication

    Dynamic C net- work software are used to develop an RS-485 network. The OP7100 can be linked together Figure 3-19. RS-485 Signals with other Rabbit Semiconductor controllers over a twisted-pair network for up to 1.2 km. When configuring a multidrop network, use single twisted-pair wires to connect RS-485+ to RS- 485+ and RS-485- to RS-485- as shown in Figure 3-20.
  • Page 41 Any Rabbit Semiconductor controller or the OP7100 can be a master or a slave. A network can have up to 255 slaves, but only one master. A multidrop network requires termination/bias resistors to minimize reflec- tions (echoing) and to keep the network line active during an idle state. The OP7100 termination resistors are already installed, and by default are en- abled by having jumpers installed on header J9.

  • Page 84: Grounding

    The connection to the building ground should always be made through the bezel. The recommended way to connect an OP7100 to a building ground is to mount the unit in a metal panel that is already grounded. Ensure that the areas around the securing nuts are clean and free from corrosion or other contaminants so that a good electrical connection can be realized.

  • Page 85: Installation Guidelines

    When possible, following these guidelines when mounting an OP7100. 1. Leave sufficient ventilation space 2. Do not install the OP7100 directly above machinery that radiates a lot of heat (for example, heaters, transformers, and high-power resistors). 3. Leave at least 8" (20 cm) distance from electric power lines and even more from high-voltage devices.

  • Page 86: Mounting

    Mounting A bezel and a gasket are included with the OP7100. When properly mount- ed in a panel, the bezel of the OP7100 is designed to meet NEMA 4 speci- fications for water resistance. Since the OP7100 employs an LCD display, the viewing angle must be considered when mounting the display.

  • Page 87: General Mounting Recommendations

    Figure 6-3. Strengthening Bracket General Mounting Recommendations If the OP7100 is mounted inside a panel, the enclosure must not be airtight to ensure that the touchscreen will not distorted by differences in air pressure. If the OP7100 is mounted in a completely airtight enclosure, a pressure differential may build up across the window overlay, and could adversely affect the operation of the touchscreen.

  • Page 110: Introduction

    Introduction The SIB is an interface adapter used to program the OP7100. The SIB is contained in an ABS plastic enclosure, making it rugged and reliable. The SIB enables the OP7100 to communicate with Dynamic C via the Z180’s clocked serial I/O (CSI/O) port, freeing the OP7100’s serial ports for use by the application during programming and debugging.

    The battery has a capacity of 265 mA·h. At 25°C, the real-time clock draws 3 µA when idle, and the 128K SRAM draws 4 µA. If the OP7100 were unpowered 100 percent of the time, the battery would last 32, 000 hours (3.6 years).
