Digital Communication Interface
Wiring
Use a digital interface to connect the Product to a computer or other equipment. A digital interface lets
you input the set-point temperature, monitor the temperature, control operating conditions, and access
any of the other controller functions. The RS-232 serial interface allows serial digital communications
over fairly-long distances. Access any of the functions, parameters, and settings discussed in this
section with the serial interface.
The serial communications cable attaches to the Product through the DB-9 connector at the back of the
Product. Figure
shows the pin-out of this connector and suggested cable wiring. To eliminate noise,
the serial cable should be shielded, with low resistance between the connector (DB9) and the shield.

Setup
Before operation, the serial interface must first be set up by programming the BAUD rate and other
configuration parameters. These parameters are programmed within the communications menu. The
serial interface parameters can be accessed from the main menu by MENU|SYSTEM SETUP|COMM
SETUP|. Refer to
Comm
for more information on the serial interface parameters.
