Keypad Connection

The GSZ67 outputs can be controlled by the MR164 keypad and/or an external controller or computer (using the RS232 port), so keypads may not be needed.

More than one or two keypads can be used in a zone and nine (9) is the maximum number of MR164 keypads per GSZ67 allowed.

Note: MR164 keypads are not designed for outdoor use, high humidity, high temperatures or any extremes.

The MR164 contains an almost all brand infrared repeater and most functions can be controlled by the Knoll RB12 remote control. RB12 commands can easily be stored in a learning remote.

The MR164 is connected to the GSZ67 with CAT5 or CATe wire. Each keypad can have a home run or be daisy chained on one wire. If you daisy chain one zone and another zone on one wire you may lose some infrared functionality. Each room or zone has a unique IR pass-thru port as indicated on the rear of the GSZ67. In addition there is an all room IR pass-thru port. If you combine two or more rooms or zones on 1 CAT5 wire the ability to individually split infrared signals will be lost. Each keypad has two RJ45 connectors that are both inputs and outputs for daisy chaining keypads together. Five of the eight CAT5 wire conductors are used.

Note: It is very important to use a top quality RJ45 8/8 crimper tool. We strongly suggest using a cat 5 / RJ45 electronic tester to verify the wire conductors.

We recommend the T568A wiring method, which is shown below.

The functions of each wire connection are also shown.
