Crestron CNIRHT-MM

30 Function Hand-Held IR

Transmitter: CNIRHT-MM

Description

Functional Description

The CNIRHT-MM is a 30 function, hand-held infrared (IR) transmitter

designed to work with the CEN-TVAV and/or CN-TVAV. By setting an

IR transmitter identification (ID) code in the CNIRHT-MM and using the

keypad buttons, any television or audio-visual (TV/AV) device attached

to the CEN/CN-TVAV may be controlled remotely. The functions of the

individual buttons are determined by the CEN/CN-TVAV and/or the

Crestron remote control system (herein referred to as the Cresnet system)

SIMPL

To prevent interference from fluorescent lighting and most standard IR

frequencies, the CNIRHT-MM operates at 455 kilohertz (kHz). The

CNIRHT-MM must have an unobstructed line-of-sight to the CEN/CN-

TVAV being controlled. A light-emitting diode (LED) on the front of the

CNIRHT-MM indicates IR transmission when any keypad button is

pressed, is used to display the IR transmitter ID code that is set into the

unit, and flashes continuously when the CNIRHT-MM battery voltage is

low.

Physical Description

The CNIRHT-MM, shown on the next page, is housed in a slim, high-

impact ABS plastic black enclosure. The front contains one LED and 30

keypad buttons. At the rear of the unit is the battery compartment that

contains one 9-volt alkaline battery (included) and a sensor (photo

transistor) that is used to set the IR transmitter ID code.
