XC-42 WIRELESS OPTION 
 
DESCRIPTION 
 
The XC-42 dimmer can be supplied with additional 
components which enable it to use a wireless DMX 
control signal. The option includes an antenna. 
 
When operated as a wireless unit the XC-42 receives 
the same information it would get using a cable 
connected to a DMX lighting console. For wireless 
operation the XC-42 can be used only with a console 
which has an compatible wireless DMX transmitter. 
 
The wireless system uses the 2.45 GHz band and 
operates at low power (< 100mW). The operating 
range is aproximately 1400 ft. indoors and about 4000 
ft. for outdoor operation. This range could vary 
significantly depending on the surrounding conditions. 
 
A link between an XC-42 dimmer and a specific 
single console is invoked to enable wireless operation. 
The linking operation is performed at the console. 
Once linked, the XC-42 can operate as wireless 
ONLY with that console. The link is retained even 
when the dimmer and/or console are powered off. 
 
The XC-42 will not link to any other console until the 
established link it released. The link can be released 
either at the XC-42 or at the transmitting console. 
 
INSTALLATION AND SETUP 
 
There are only three steps to perform to operate the 
XC-42 in the wireless mode. 
 
1. Install the supplied antenna. The antenna threads 
onto a SMA connector located in the end of the unit. 
Do not overtighten it or wrench it down. It can be 
rotated into a convenient position when installed. 
 
2. Link the unit to a compatible console. This is done 
at the console. 
 
3. Set the control source to wireless (Antd). This is 
done using the SYSt, CnFG menu on the XC-42 
dimmer. 
 
 
 
 
LINKING TO A WIRELESS EQUIPPED CONSOLE 
 
A link between an XC-42 dimmer and console is 
performed by using a button on the console. This 
causes the console to search out and link all wireless 
dimmers within its range which are not already linked 
to another wireless control source. The wireless link 
LED on the console is ON when the wireless 
transmitter section is getting a DMX signal from the 
main console circuits. 
 
The XC-42 has two indicators which show wireless 
status. One is a green LED in the end of the unit near 
the antenna. The other is a dot in the main display. 
These indicators function identically as follows: 
 
Not linked to a console - indicators OFF. 
Linked but not receiving a signal - indicators FLASH. 
Link process in progress - indicators FLASH FAST 
Linked and receiving a signal - indicators ON 
 
TO LINK AN XC-42 TO A CONSOLE 
 
Push (DO NOT HOLD DOWN) the wireless link 
button on the console. The green wireless link LED 
on the console and the dimmer indicators will flash. 
After aprox. 10 seconds the console LED will revert 
to ON but the dimmer indicators will continue to flash 
at a rapid rate for several more seconds until a solid 
link is established. The XC-42 indicators will be ON 
when a link is fully established. 
 
The XC-42 can link can even if is not in the wireless 
mode but since the unit can operate in several other 
modes it will not respond to the wireless commands 
unless switched into wireless operation (Antd)from 
the display SYSt, CnFG menu. 
 
The XC-42 factory reset function does not log the unit 
off but it does take it out of wireless mode. 
 
UNLINKING AN XC-42 FROM A CONSOLE 
 
An unlink operation can be done either at the dimmer 
or at the console. If done from the dimmer then only 
that specific XC-42 will be released from the link and 
it can then be linked by another compatible wireless 
controller or relinked to the same one. If the unlink 
operation is done at the console then ALL dimmers 
linked to it and in receiving range will be released.
