Enrange CHTX Transmitter Instruction Manual
December 2017
Page 35 of 47
Serial Number
This field displays the serial number for the unit. The serial number of the unit is set by the factory and
cannot be modified by the user.
Access Code
The access code acts as the transmitter address. The transmitter will only transmit commands to receivers
with the same address. This feature is selectable by the user.
NOTE:
The transmitter must be set with the same access code as the receiver in order for them
to properly communicate with each other.
RF Channel
The RF channel is user-selectable through the pull-down menu. This function is used to prevent
interference with other radio devices. The user-selectable channels for 400 MHz, 900 MHz and 2.4 GHz
systems are 1 through 32.
See Section 6.2 on page 41
for channel frequency details.
NOTE:
If using the optional RCP software on transmitters NOT equipped with the graphic user
interface, the channel settings will read from the dip switch positions and not from memory when
the channel from memory override function is not enabled. The RF channel set by the optional
RCP software will not be used unless the memory override dip switch is set to ON. When the RF
channel from memory override is NOT enabled, the dip switch positions set the RF channel
used by the transmitter.
Inactivity Timeout
The transmitter can be set to turn off after a period of time when no controls are activated. To restart the
transmitter, the OFF/ON/START switch must be cycled through the start procedure. The factory default
setting for the inactivity timeout is 15 minutes.
RF Power
The RF transmitting power of the unit is user-selectable through the drop-down menu. This function is
used to reduce the operating range of the transmitter from the equipment being operated. The user-
selectable options for RF power are MAX, 50%, 25% and MIN.
Activate Password
The password is used to restrict access to the configuration menu on the CHTX. Having an active
password prevents accidental changes to the transmitter.
WARNING
The access codes in the receiver are unique and factory preset. Do not change these access codes
unless you are replacing an existing receiver and its access code. Changing this code could make it
common with another receiver access code, which could move other equipment. No two systems in
any location should ever have the same access codes independent of frequency. Failure to follow this
warning could result in serious injury or death, and damage to equipment.
