Cable Length and Data Rate
By default, the module is set up to operate with the maximum length expansion
cable at the default data rate of 250Kbits/second. If the total length of the
expansion cable is less than 250 m and there are no non-isolated Expansion
Receivers (IC200ERM002) in the expansion system, the VersaMax PLC
programmer allows the data rate to be configured to 1Mbit/second. In an NIU
I/O Station, the data rate cannot be changed from the default 250Kbits.
Terminator Plug
The terminator plug supplied with the Expansion Transmitter Module must be
installed in the lower connector of the last Expansion Receiver in the chain as
displayed above.
