Serial Port #1 Wiring: CPU KGR8924–1
Serial Port 1 supports full-duplex RS-232, or 20mA current loop (active or passive), or half-duplex RS-485. Switch
S1 (shown below), selects the interface protocol of Port 1..

) Notes:
1. A pull-down biasing resistor (100K OHMS typical) should be installed between TB5-1 and TB2-5.
2. A pull-down biasing resistor (100K OHMS typical) should be installed between TB5-2 and TB2-4.
3. If the UMC600 is the last device (node) on the RS-485 network, a termination resistor (100 OHMS typical) should
be installed across TB5-1 and TB5-2.
