4.7 Serial Port Connections
4.7.1 Providing Power to an External Device from
Port 2
If either port is set up for communications with a serial device that requires 100mA or
less at 5VDC, the device can obtain power from Port 2.
4.7.2 Cable Lengths and Baud Rates
Maximum cable lengths (the total number of feet from the CPU to the last device attached
to the cable) are:
Port 1 (RS-232) = 15 meters (50 ft.)
Port 2 (RS-485) = 1200 meters (4000 ft.)
Both ports support configurable baud rates, as listed in the CPU descriptions in this
manual.
