J6 - Serial; Rs 232/Rs 485 Communication Description; Communication Format - Agilent Technologies TPS-compact Mode D'emploi

How to connect the outputs of the controller
The following figure shows a typical logic output
connection (relay coil) but any other device may be
connected e.g. a LED, a computer, etc., and the
related simplified circuit of the controller. The fig-
ure example refers to the programmable set point
signal on pins 11 and 9.

SIGNAL NAME
RS 232/RS 485 COMMUNICATION
DESCRIPTION
Both the RS 232 and the RS 485 interfaces are
available on the connector J6.
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 is
necessary to select the type of communication as
well as the device address by means of the soft-
ware.

Communication Format

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