5. USING THE GFW/GPC-OP KEYPAD
5.1. Description
The programming keypad is used to display status param-
eters and for diagnostics during operation. It can also be
used to modify a large number of GPC parameters.
The keypad has a 5 x 21 character liquid crystal display.
A membrane keypad is used for navigation and controls.
There are also 6 LEDs for signalling.
A strip of magnetic material is located on the back of the
keypad so that it can be fixed to the front of the GPC-M or
to a metal surface (e.g., the switchboard door).
The keypad (GFW/GPC-OP cod. F068952) comes with a 70
cm cable with a DB9 male connector for connection to the
