QTERM-R55 Handheld Terminal
The dimensions of the QTERM-R55 handheld terminal are
shown in Figure 3-1. This figure also shows the standard
keypad legend for the keys on the 40-key keypad.
The housing is made from impact-resistant ABS and is col-
ored black. The housing is not waterproof, but it can be
subjected to moderate rain or splash without harm.
The QTERM-R55 handheld terminal uses a 6-pin modular
jack, exiting from the bottom of the housing. If desired, the
modular jack can easily be switched to exit from the top of
the QTERM-R55 housing.
The pin assignments for the connectors for each of the
available interfaces are shown in Table 3-2. Figure 3-2
shows the pin numbering for the connectors used on the
QTERM-R55. For reference, Table 3-1 shows the pin
assignments used by the COM ports on PC-style computers
for both DB25 and DB9 connectors.

QTERM-R55 Panel-Mount Terminal
The panel-mount QTERM-R55 is mounted directly onto
your instrument or enclosure. Figure 3-3 shows the dimen-
sions of the panel-mount QTERM-R55 along with the stan-
dard keypad legend for the 24-key keypad.
The QTERM-R55 is mounted to the panel by placing the
terminal into the panel cutout and attaching the rear shell
behind the panel with the four self-tapping screws. A
mounting gasket is provided in order to seal the front edge
of the terminal. Figure 3-4 shows the assembly diagram
along with the panel cutout dimensions required for mount-
ing.
