Installing
Optional
Modules
This section presents installation procedures for the M
x
800 Series terminal’s
optional modules. The M
x
800 Series terminal model you have, may already have
some of these options. Modules can be installed at the factory or in the field.
Installing Smart
Card Modules
The following are the steps required to install optional I/O modules:
1 Loosen the module retaining screw on the bottom of the M
x
800 Series (Figure
7) until the old module can slide out.

2 Slide the smart card module into place (Figure 8) and secure the retaining
screw.

NOTE
The retaining screws are captive, which means they do not actually separate
from their seats, but only from the mounting hole.
