interface menu. The serial interface parameters menu is outlined in Figure 4 on
page 20.
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 “PAr”. Press “UP” 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.
8.1.2.1 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 is displayed. The BAUD rate of the
9103 serial communications may be programmed to 300, 600, 1200, 2400,
4800, or 9600 baud. The BAUD rate is pre-programmed to 2400 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.
8.1.2.2 Sample Period
The sample period is the next parameter in the menu and prompted with
“SPEr”. 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 instrument transmits the current measurement over the serial interface ap-
proximately 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.
8.1.2.3 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 command received by the instrument via the serial interface is im
-
mediately 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”.
8.1.2.4 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”.
