3DESCRIPTION

This publication provides instructions for installing the

LTC 2604 Multiplexer Keyboard Port Expander in a

LTC 2600 System 4 Multiplexer System.

A single LTC 2604 unit can be used to interface up to

four keyboards in a Multiplexer system.

The LTC 2604 unit is compatible with any

combination of the following models of keyboards:

LTC 2601/00, LTC 2602/00, KBD-DIGITAL,

KBD-MUX, or KBD-UNIVERSAL, Divar® Series

Recorders.

For more than two LTC 2601/2 keyboards used in an

expanded configuration, one LTC 8557 Series Keyboard

Extension Kit (not included) will be required for each

additional keyboard.

Each Multiplexer Keyboard Port Expander is supplied

with a single white cable. This cable is used to connect

the Port Expander to the keyboard port of a System4

Multiplexer. The LTC 8557 Series Kit is then used to

connect the expanded keyboards to the LTC 2604 Port

Expander. See Typical Application Diagrams found at

the end of this manual.
