RS 232 Communication Port
The communication serial port connections and the
minimum connection configuration are shown in the
following figures.
Communication serial port connections
Minimum connection configuration
The communication port mating connector is supplied
with the RS 232 PCB (AMP/Cannon or equivalent 15-
pin "D" type male connector).
The external cable (not supplied) between the host
computer and the controller doesn't require any
crossed wires so that the signal are connected
correctly.
For example, the Transmit data signal from controller
(pin 2) must be connected to the host computer's
Receive data line (pin 2) and vice versa. Consult the
host computer's instruction manual for its serial port
connections.
Varian cannot guarantee
regulations for radiated emissions unless all external
wiring is shielded, with the shield being terminated to
the metal shroud on the 0-subconnector. The cable
should be secured to the connector with screws.
