Please Note: Each remote control system manufacturer uses a unique security code protocol, therefore the above transmitters can only be used with the specific make & model of equipment for which they were intended and will not be compatible with any other make of remote control system even if the radio frequency is the same

30.9MHz - Green buttons TR301, TR302, TR304 receivers, AF30 frequency heads
26.9MHz - Blue buttons TR261, TR262, TR264 receivers, AF26 frequency heads

Coding
TOP transmitters send a 12 bit code made up from a 10 bit site code plus a 2 bit channel code. This gives 4096 combinations. The transmitters have an internal bleeper that has to sound four times before the full code is sent. Programmable receivers treat the channel code as an extension of the site code. Transmitters are supplied with a CAME default code [0101010101] so that the system can be commissioned.  It is recommended you set a random site code for new installations.

Receiver channels
The outputs on the single and dual channel receivers can be selected by jumper link to respond to any of
the four transmit channels. The four channel receiver has a separate output for each channel. Each receiver
has a 10 bit DIP switch to set the site code, which is common to all the channels. Programmable receivers
treat the channel code as an extension of the site code.

Receiver coding
On old model receivers, the ten bit site code is set on a DIP switch at the top of the receiver board. You will
need to read the site code from the receiver DIP switches and make a note of the sequence.  The switches are marked OFF and ON. When writing this down 0 is OFF, and 1 is ON.

From 1998, the old plug in receivers were replaced by a radio receiver head (AF26 or AF30) and decoder
board (RBI-1 or RBI-2).  New control boards have the programmable decoder incorporated (ZA3, ZA4, ZA5,
ZL19, ZL37, ZL54). It is not possible to read the code from a programmable decoder. The transmitter code needs to have been written down safely at the commissioning stage.

Transmitter buttons
The T262M and T302M are two button transmitters whose transmit channels can be selected by programming jumpers.  Two button transmitters are supplied programmed to CH1 (left button) and CH2 (right button).
T264M & T304M are four button versions: CH1 top left, CH2 top right, CH3 bottom left, CH4 bottom right.

Transmitter programming
CHANNEL METHOD. Open the battery compartment and hold with the battery towards you. Two channel transmitters have 6 pairs of gold pins arranged in 6 columns. Columns are numbered from right to left. Channel setting for the left button is made by linking columns 1 or 2. (1 =CH1 2=CH3) Channel selection for the right button is made by linking columns 3, 4 or 5 (3=CH2 4=CH3 5=CH4)

SITE CODE METHOD. The sixth column of a two channel transmitter is for programming.  Jumper links must be set in column 1 & 3 during programming. Four channel transmitters only have the programming jumper column. Its link is stored on one pin only. To start programming, place the jumper across both pins. Press buttons 1 & 2 to enter the site code, using left for '0', and right for '1'. The transmitter beeps each press of a button, and twice at the end of the sequence of ten presses. Remove the programming link immediately and store.
