The Micro-Bath calibrator is capable of communicating with and being con trolled by
other equipment through the digital serial interface.
With a digital interface the instrument may be connected to a computer or other
equipment. This allows the user to set the set-point temperature, monitor the
temperature, and access any of the other controller functions, all using remote
communications equipment. Communications commands are summarized in Table 5
on page 48.

Serial Communications

The calibrator is installed with an
RS-232 serial interface that allows
serial dig ital communications over
fairly long distances. With the serial
interface the user may access any of
the functions, parameters and settings
discussed in Section 9 with the
exception of the BAUD rate setting.

Wiring

The serial communications cable
attaches to the calibrator through the
DB-9 connector at the back of the
instrument. Figure 8 shows the pin-
out of this connector and sug gested
cable wiring. To eliminate noise the
serial cable should be shielded with
low resistance be tween the connector
(DB-9) and the shield. If the unit is
used in a heavy industrial setting, the
serial cable must be limited to ONE
METER in length.

Setup

Before operation the serial inter face
must first be set up by pro gramming the
BAUD rate and other configuration parameters. These parameters are programmed
within the serial interface menu. The serial interface parameters menu is outlined in
Figure 7 on page 32.
To enter the serial parameter pro gramming mode first press "EXIT" while pressing
"SET" and release to enter the secondary menu. Press "SET" re peatedly until
the display reads "PAr". Press "UP" until the serial interface menu is indicated
with"SErIAL". Finally press "SET" to enter the serial pa rameter menu. In the serial
