Panel-Mount QTERM-P40

The dimensions of the QTERM-P40 are shown in Figure 6-
1. This terminal is available with a 24-key or a 40-key key-
pad each with user-specified LED labels and function keys.

The housing is made from rugged glass-fiber filled nylon
plastic and is colored black. The housing is not waterproof,
but it can be subjected to moderate rain or splash without
harm.

The QTERM-P40 is mounted directly onto your instrument
or enclosure panel. Figure 4-1 shows the mounting cutout
required to install the QTERM-P40.

The QTERM-P40 is mounted to the panel via four angle
brackets that attach to the terminal with self-tapping screws
that insert from the rear of the bracket and screw into
bosses on the QTERM-P40 enclosure. These brackets are
designed so they can be attached before inserting the termi-
nal into the panel. Once the brackets have been installed,

the terminal is inserted into the panel and the brackets are
slid outward. Then the screws are tightened and the brack-
ets hold the terminal in place. Screws and brackets are
included with the QTERM-P40; these are usable with pan-
els up to about 10 mm thick. A gasket is provided to seal
the outside edges of the terminal where it presses against
the panel. Connection to the panel-mount QTERM-P40 is
made via the ten-pin terminal strip or the DB9 connector
which is accessible on the back of the terminal. The lines
dig0 and dig1 are discussed in section 6.3.3. The connector
pin numbering is shown in Figure 6-2.

Interfaces

6.2.1

EIA-232 Interface

With proper cables and good grounding, the EIA-232
QTERM-P40 can communicate up to 15 meters at its top
speed of 9600 baud.
