1. When the device is located at the end of a transmission line via
twisted-pair cable, (when there is no cross-wiring), close across the
terminal T2 – T3 with a leadwire.
When the device is not at the end, no shortcircuit wire is required.
*
2. For ‘External interface’ code 7, 8, 9 and A, the analog outputs are
isolated between each other.
