RS 232/RS 485 COMMUNICATION
DESCRIPTION
Both the RS 232 and the RS 485 interfaces are available on
connector J2.
The communication protocol is the same (see the structure
below) but only the RS 485 manages the address field.
Therefore, to enable the RS 485, it is necessary to select the
type of communication as well as the device address by
means of the T-Plus.

Communication Format

•
8 data bit
•
no parity
•
1 stop bit
•
baud rate: 600/1200/2400/4800/9600 programmable

The communication port mating connector is supplied with the
RS 232 PCB (AMP/Cannon or equivalent 15-pin "D" type male
connector).
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 compliance with ECC regulations on
radiated emissions unless all external wiring is shielded, with
the shield terminated on the metal enclosure on the
0-subconnector. The cable should be secured to the connector
with screws.
Serial Communication Descriptions
This unit can communicate using two different protocols:
- protocol (old system) "letter"
- "Windows" protocol (new system)
These two protocols can be used as well with 232 or
485 media.
Please use "Windows" protocol for new development.
