Calibration Bath
Digital Communication Interface

Setup
Before operation the serial interface of the bath must first be set up by
programming 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 6. To enter the serial
parameter “EXIT” while pressing “SET” and release to enter the secondary
menu. Press “SET” repeatedly until the display reads “ProbE”. This is the menu
selection. Press “UP” repeatedly until the serial interface menu is indicated with
“SErIAL”. Finally press “SET” to enter the serial parameter menu. In the serial
interface parameters menu are the baud rate, the sample rate, the duplex mode,
and the linefeed parameter.
Baud Rate
The baud rate is the first parameter in the menu. The display will prompt with the
baud rate parameter by showing “BAUd”. Press “SET” to choose to set the baud
rate. The current baud rate value will then be displayed. The baud rate of the
serial communications may be programmed to 300,600,1200, or 2400 baud. The
baud rate is pre-programmed to 1200 baud. Use “UP” or “DOWN” to change the
baud rate value. Press “SET” to set the baud rate to the new value or “EXIT” to
abort the operation and skip to the next parameter in the menu.
Sample Period
The sample period is the next parameter in the menu and prompted with
“SAmPLE”. The sample period is the time period in seconds between
temperature measurements transmitted from the serial interface. If the sample
rate is set to 5, the bath transmits the current measurement over the serial
interface approximately every five seconds. The automatic sampling is disabled
with a sample period of 0. Press “SET” to choose to set the sample period.
Adjust the period with “UP” or “DOWN” and then use “SET” to set the sample
rate to the displayed value.
Duplex Mode
The next parameter is the duplex mode indicated with “dUPL”. The duplex mode
may be set to half duplex (“HALF”) or full duplex (“FULL”). With full duplex any
commands received by the bath via the serial interface are immediately echoed
or transmitted back to the device of origin. With half duplex the commands are
executed but not echoed. The default setting is full duplex. The mode may be
changed using “UP” or “DOWN” and pressing “SET”.
Linefeed
The final parameter in the serial interface menu is the linefeed mode. This
parameter enables (“On”) or disables (“OFF”) transmission of a linefeed
character (LF, ASCII 10) after transmission of any carriage-return. The default
setting is with linefeed on. The mode may be changed using “UP” or “DOWN”
and pressing “SET”.
