|
The SDEC LCD modules are fitted to the Watchguard Firebox firewall appliances.
|
|
Watchguard identifies these units by the X-Core, X-e and X-Peak product lines.
|
|
The model number indicates a software license level, and has no bearing on the
|
|
hardware configuration.

|
The SDEC LCDs are interfaced to the appliance using a parallel port. All lines
|
|
are hard-wired by Watchguard.
|
|
The LCD displays are 20 characters wide and 2 lines high, and
|
|
have 4 buttons: <literal>Up</literal>, <literal>Down</literal>,
|
|
<literal>Left</literal>, and <literal>Right</literal>. The SDEC model number is
|
|
<literal>LMC-S2D20-01</literal>. There is a back light that can be controlled
|
|
by software. Due to its low half-life, the driver tries to keep the light off a
|
|
short while after buttons have been pressed.
