The IC697BEM731 is a GE series 90-70 bus controller module. This module is mainly used to connect with other modules, perform I/O scans and transfer data to the CPU, initiate communication with the CPU, report alarms, and link other devices (such as PCIM). The module has one (1) channel for communication with remote modules, one (1) handheld monitor port, and each channel supports up to thirty (30) discard, redundant blocks, and handheld monitors.

The IC697BEM731 has one (1) channel for connecting to devices residing on the same bus, and one (1) handheld monitor (HHM) port for downloading the configuration to the module using the MS DOS or Windows programming software Configurator feature. When IC697BEM731 was delivered, it did not have a defined bus address. The configuration software sets the default address to 153.6 Kbaud standard and the bus address to 31. This default address can be modified by downloading the valid configuration to the CPU. When configured as 2000 Kbaud (standard), the maximum allowable distance of the communication bus is 153.6 feet; 3500 feet when configured at 153.6 KBaud (extended); 4,500 feet at 76.8 KBaud configuration and 7,500 feet at 38.4 KBaud configuration. All devices residing on the same bus or network must be configured with the same baud rate, otherwise communication cannot be established or you may experience erratic communication.
