OM200 multiplexer Interface
8 channel relay sense and closure
This interface contains eight ports. The ports may be configured as either contact sense (inputs) or contact closure (outputs) or a mixture of both. The isolated dry contact outputs close when the corresponding input pins at the remote end are shorted (or are driven high by an RS232 signal).
This interface may be used in an Add-Drop topology where one or more input nodes share a channel which shows up at one or more output nodes. A contact closure at any of the input nodes closes the corresponding contacts at the output nodes. All of the input nodes must be adjacent to each other, and all of the output nodes must be adjacent to each other. The inputs must idle in the open state (negative for RS232); otherwise an input will monopolize the channel. To set this up, use the network management interface as follows:
1. Set the desired port to Input on input nodes.
2. Set the same port to Output on the output nodes.
3. Set up a Data Connection between each card and any other card in the chain.
Each card may be a mixture of inputs and outputs in this mode.
