Connecting Your V550-A20 To An External Device
RS-422 (point to point)
Use the following drawing as a guide when you want to connect your
V550-A20 to a device that is using RS-422 serial communication:
NOTE: Termination resistors may be placed inside the connector strain relief.
The termination resistor value is 220 OHM 1/4 watt.
With RS-422, the receive lines on both sides must be terminated.
CABLE TYPE: ALPHA #5473C (OR EQUIVALENT).
