up by programming the baud rate and other configuration parameters. These
parameters are programmed within the serial interface menu.
To enter the serial parameter programming mode first press "EXIT" while
pressing "SET" and release to enter the secondary menu. Press "SET" repeat-
edly 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 parame-
ters 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 7012 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 "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 7012 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 thermometer via the serial interface are
immediately echoed or transmitted back to the device of origin. With half du-
plex the commands are executed but not echoed. The default setting is full du-
plex. 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".
