"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 "SE-
rIAL". Finally press "SET" to enter the serial parameter menu. In the serial in-
terface 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 prompts with the
baud rate parameter by showing "BAUd". Press "SET" to choose to set the
baud rate. The current baud rate value is displayed. The baud rate of the serial
interface 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 "SAm-
PLE". 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 approxi-
mately 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 dis-
played 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 immedi-
ately 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 pa-
rameter enables ("On") or disables ("OFF") transmission of a linefeed charac-
ter (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".
Serial Operation
Once the cable has been attached and the interface set up properly the control-
ler immediately begins transmitting temperature readings at the programmed
rate. The set-point and other commands may be sent to the bath via the serial
