Digital Communication Interface
The Bath can communicate with and be controlled by other equipment through the digital
interface. An RS-232 serial interface which is standard and an IEEE-488 GPIB interface is
optional. See
Serial Interface Parameters
With a digital interface, the Bath can connect to a computer or other equipment. Use the remote
communication equipment to:
•
set the Bath temperature
•
monitor the temperature
•
access all controller functions
•
control cooling
The cooling power switch must be on (I) to control the cooling with the interface.
Serial Communications
The RS-232 serial interface allows serial digital communications over fairly-long distances
(15.24 m). The serial interface can access any of the controller functions, parameters, and
settings discussed in
serial interface operates with 8 data bits, 1 stop bit, and no parity.
Wiring
The serial communications cable attaches to the Bath through the DB-9 connector on the rear
panel.

shows the connector pin-out and suggested cable wiring. To eliminate noise, the
serial cable should be shielded with low resistance between the connector (DB-9) and the shield.
