4.3.6 Connecting the Expansion Cable: Single-ended
For a system with one non-isolated expansion rack (IC200ERM002) and NO Expansion
Transmitter, connect the expansion cable from the serial port on the VersaMax CPU to the
Expansion Receiver as shown below. The maximum cable length is one meter. Cables
cannot be fabricated for this type of installation; cable IC200CBL600 must be ordered
separately.

No Terminator Plug is needed in a single-ended installation; however, it will not impede
system operation if installed.

4.3.8 Power Sources for Single-ended Expansion
Rack Systems
When operating the system in single-ended mode, power supplies for the main rack and
expansion rack must use the same main power source. The main rack and expansion racks
cannot be switched ON and OFF separately; either both must be ON or both must be OFF
for proper operation. Power for modules in the expansion rack comes from the Power
Supply installed on the Expansion Receiver Module. If the expansion rack includes a
Power Supply Booster Carrier and additional rack Power Supply, it must be tied to the
same source as the Power Supply on the Expansion Receiver Module.
