Auxiliary Serial Port Option
If you ordered the Auxiliary Port option with your
QTERM-IV, you have an additional connector. On hand-
held units, this is a DB9 connector which exits from the
same end of the case as the 6-pin Modular connector; on
panel-mount units, this is a 6-pin, 2 mm connector (Figure
5-4).
Table 1-2 shows the pin assignments for both the panel-
mount and handheld connectors. The handheld DB9 will
mate directly with the DB9 male on an HP SmartWand bar
code reader.
The auxiliary serial port operates at 1200 baud with a data
format of 8n1. The QTERM-IV host port must operate at
1200 baud or faster when using the auxiliary port option.
This serial port does not support XON/XOFF handshaking.
See section 2.2.46 for a detailed description of the opera-
tion of the auxiliary port.
5.5.7
The EEPROM Disable Jumper
Figure 5-4 shows the location of the EEPROM disable/
enable jumper. This is shipped in the enable position,
which allows the EEPROM to be modified with QDATA
downloads or the Save Parameters to EEPROM command.
If you do not want the EEPROM to be modified under any
conditions, move this jumper from the enable to the disable
position. This will prevent any writes to the EEPROM,
including downloading of QCODE or QDATA files.

Adding Another PC Board
If you are using a handheld or battery back QTERM-IV,
you can install an additional PC board in the back of the
case. This board can be used, of course, for whatever pur-
pose your application requires.
Figure 5-5 shows the physical size of this printed circuit
board, as well as the allowable component height. There are
plastic bosses molded into the back of the case; you can use
all or just some of these for mounting your PC board. The
ones you do not wish to use can be easily clipped off.
For the bosses that you do want to use, place a 3.2 mm
diameter hole in your PC board. After the PC board is
installed over the bosses, you can either press on a retainer
snap ring (Eaton-Tinnerman part number T99220SS-67-01-
10780) or heat-stake the bosses.
