Note: For proper network termination, it is essential that the terminating devices maintain power. Power is provided by the device on Pin 6 and Ground on Pin 5. If power is lost to either terminating device, the network may not operate correctly. Generally, the lone network master device is one of the terminating devices. Therefore, a loss of power to the network master renders the network inoperable anyway. The other terminating device may be a critical slave device, which must maintain power, or a separately powered, stand-alone terminator. These stand-alone devices are commercially available.

Network Baud Rate

The master configures the appropriate network baud rate for each station on the network. Typical baud rate values are: 9.6KBps; 19.2KBps; 45.45KBps; 93.75KBps; 187.5KBps; 500KBps; 1.5MBps; 3MBps; 6MBps; or 12MBps. For details on using the configuration software, refer to chapter 3.

Removing the Module from the Rack

The following procedure describes how to remove the GE Fanuc Series 90-30 master:

1.Turn off power to rack.

2.Remove all cabling from the module.

3.Press the release latch located on the bottom of the module and slowly raise the module from the bottom until it comes out of the slot.
