1,2 & 4CH-SRX Four Channel Remote Control Receiver Platform
The 1,2 & 4CH-SRX platforms provide one, two or four independently binary coded output channels. Each
relay ouput is user configured through jumper settings to select either latched mode or pulsed mode. The four
bit address for each output channel is user configured by means of SIP switches. The power supply input and
channel output connections to external equipment are made via screw terminal connector blocks. The status
of each channel is visualized by its corresponding LED
. Received data is automatically error checked, there-
fore minimising the possibilities of false triggering.
The platform address is set by means of an eight position SIP switch, providing up to 256 possible address
combinations. Both the module address and channel addresses are decoded with a Holtek HT12F decoder IC
and therefore will respond to similarly encoded bit patterns from a Holtek HT12E encoder IC or a microcon-
troller on the transmitter end. The antenna connection is via a PCB pad and is suitable for direct soldering
either a 1/4 wave wire antenna or for taking 50Ω coaxial feed to a suitable external antenna connector.
NOTE: To preserve flexibility, the 1,2,or 4CH-SRX platform is designed to use, but does not include, the
SILRX-4xx-A series receiver module. The SILRX-4xx-A module on the desired frequency must be ordered ad-
ditionally. (see ‘ Receivers’ for details )

The 4CH-SRX is also available in one and
two channel versions; the 1CH-SRX and
the 2CH-SRX.
All three -SRX- versions are suitable for
pairing up with the 1-6CH-TXM platforms
to complete the remote control link.
