DMake sure that rack power is off.

DInstall the CSE 925 module in slot 1 of rack 0 (see Figure 2).

DTurn on power.

The module should power up and the top LED should blink. When the diagnostics have completed successfully, the top LED stays on and the second and third LEDs are off. The fourth LED is off if the keyswitch is in the OFF position. The CPU is now ready to be programmed.

After the program has been verified the toggle switch may be moved to the appropriate operation mode position. The LEDs indicate the position of the toggle switch, memory protection status, and the state of the program.

The IC641 (MS-DOS)software is also used to load the State Logic operating system into the CSE 925 CPU module. The operating system is provided on a floppy disk with the CSE 925. The operating system is stored in flash memory on the module. For information on loading the operating system, see the State Logic Control System User's Manual.

Serial Port

The 15-pin D-connector provides the connection to an RS-485 compatible serial port on the CPU as shown in Figure 2.

The serial connection is made from the serial port on the CPU to the serial port on the programming computer,or other serial device, through the RS-422/RS-485 to RS-232 Converter (IC690ACC900) or RS-232 to RS-422 Miniconverter (IC690ACC901). This connection can be made with available cables or you may build cables to fit the needs of your particular application. See reference 3 for more information on serial communications.

Configuration

The IC697 CPU and I/O system is configured with IC641 (MS-DOS)programming software. There are no DIP switches or jumpers used to configure the system. The CPU verifies the actual module and rack configuration at power-up and periodically during operation. The actual configuration must be the same as the programmed configuration. Deviations are reported to the CPU alarm processor function for configured fault response. Consult Reference 1 for a description of configuration functions.

Batteries

A lithium battery (IC697ACC701) is installed as shown in Figure 1. This battery maintains program and data memory when power is removed and operates the calendar clock. Be sure to install the new battery before removing the old battery. Specific indication of a low battery state is detailed in Reference 2.
