Radio Code Settings
Each pushbutton on the TXC-MS(L) transmitter represents an Axcess channel number. All of the
pushbuttons on the transmitter represent a group of channel numbers. This grouping is known as a
radio code. Use the transmitter DIP switch to assign a unique radio code to this transmitter. Radio
codes are important in applications that use more than one transmitter, because each transmitter
must be assigned its own unique radio code. This is necessary to avoid interference between two or
more transmitters.
The radio code is set with the last four positions on the eight-position transmitter DIP switch (see
FIG. 7 on page 7). After the radio code is set on the transmitter, each button you press sends a
specific channel number to the control system. For example, if your TXC-MS(L) transmitter is set
to radio code 4 and you press button 1, channel number 64 is sent to the control system.
Setting radio codes
The following table lists the radio codes, DIP switch positions, and channel code ranges for the
TXC-MS(L). The formula to determine the channel number of a TXC-MS(L) transmitter button is:
(Pushbutton number - 1) + (Radio code number multiplied by 16).
FIG. 9 shows the pushbutton configuration of the TXC-MS(L).
