4. THE 1320 CONTROL PANEL (2RU)

4.1 Overview

The EASi-COM 1320 Control Panel is a 2RU by 19-inch rack mounting unit. The Matrix

powers the Control Panel for distances up to 150m but for greater distances the panel

can be powered from an external supply. The panel can then be located at distances

up to 500m, depending on cable type.

The Control Panel features sixteen pushbutton Direct Access Keys (DAK) which allow

communication with all ports in the system. The DAKs can be programmed to have

separate Talk and Listen actions or a combined Talk + Listen action. All programming

is lost when power is removed, but jumpers on the Control Panel circuit board can set

the power on defaults.

This Control Panel is equipped with a DTMF keypad to dial up across telephone lines

when an appropriate Telephone Hybrid is connected to the Matrix.
