5.1.6 EIA-485 TERMINATE SWITCH

EIA-485 termination has special requirements and limitations. See Appendix 8.3 for details.

Single Cluster:

Set the EIA-485 Terminate Switch on the module (connected via the Phoenix connector) to “ON”.

Multiple Clusters:

Set the EIA-485 Terminate Switch to “ON” ONLY on the module (connected via the Phoenix connector) at the end of the EIA-485 cable run furthest from the computer. Set all other Terminate Switches to “OFF”.

CAUTION: Engaging the EIA-485 Terminate Switch on more than one module on the EIA-485 cable run can cause intermittent or nonexistent communications.
