This will activate the RS232 setup options sub menu.
The first screen that appears after the selection of RS232
from the main setup menu is:
RS232 interface
Disable Enable
The RS232 interface must be enabled (activated) for the
HHC to communicate with any RS232 device. When
the RS232 is not in use it is recommended that the
RS232 interface be disabled to conserve on power use
and maximize battery life.
Step 4 Use the arrow keys to select the word Enable.
When selected the word Enable will flash.

Step 6 After entering the Enable option the HHC will
respond with the following display.
Baud Rate
9600 2400 1200 300
The currently selected baud rate will be flashing.
Step 7 Using the left/right arrow keys select the desired
baud rate. The selected baud rate will flash on the dis-
play of the HHC.
Baud Rate
9600 2400 1200 300
In this above example the baud rate 9600 has been selected.
Step 8 With the desired baud rate selected and flashing
press the enter key.

xx.x
Step 12 Using the number keys enter the desired end
of message character in decimal code. A list of the avail-
able ASCII characters and their corresponding decimal
codes is provided in Appendix B. The inquiry character
acts as a signal to the HHC to transmit a data set. The
inquiry character is transmitted to the HHC from the
computer or other device controlling the data transmis-
sion activities. Select an inquiry character to be used in
programming as the transmission prompt.
Step 13 With the decimal representation for the desired
inquiry character displayed press the enter key.

base or spreadsheet program the end of message charac-
ter must be selected in accordance with the requirements
of the application software.
Using the number keys enter the decimal code for the
selected end of message character. A list of the decimal
codes for the available ASCII characters can be found in
Appendix B.
Step 15 With the desired decimal representation for the
ASCII character entered and displayed press the enter key.
