SR-RCS-202U Garage Door Receiver Upgrade Kit Connection Guide

Our SR-RCS-202U receiver can be useful when you want to upgrade your old garage door opener remote, or you want to control different brands of garage door openers using one remote.

Recently we have helped one customer with the SR-RCS-202U receiver installation on two garage door openers, one is some Merlin model, while the other is ATA GDO-7 V1.

The basic idea of connection includes two parts, one is using two wires to draw power from your garage door opener to our 202U receiver, the other is using another two wires to output control signal from 202U to your garage door opener.

So basically we will need 4 wires in total, 2 for power line and the other 2 for control logic, the control lines usually needs to be attached to your opener’s manual override terminal or push button terminal.

There is also a 3 wire system, since one control wire can be wired together with GND power line, sharing the same wire connection.

Here is our customer’s Merlin garage door opener, let’s take a look.

 

As you can see, there are 5 terminals on this Merlin garage door opener, namely LAMP – P/B – OBS – GND – +15V.

LAMP is for in-garage lamp control, in this case we will focus on door control, so we can leave this terminal alone.

OBS stands for obstacle, and is useful to connect photoelectric safety sensor devices, we can leave this alone in this case.

P/B stands for push button connection, and is the terminal we need to use 202U to control the door.

GND and +15V are power terminals, which will be used to draw power to our 202U receiver unit.

So the correct connection would be as follows.

GND and +15V ~ connect to our 202U’s power terminal.

GND and P/B ~ connect to our 202U’s N/O and COM terminals in either relay group.

After that, you can test your door function using remote that is programmed into our SR-RCS-202U receiver unit, the door should work as expected.

Then let’s take a look at a more popular garage door opener model in Australia – ATA GDO series.

As you can see, there are total 6 terminals on ATA GDO-7 V1 garage door opener, which are COM – OSC – LGT – PE – 0V – 24V

PE stands for trigger for the door, and LGT stands for in-garage light trigger.

COM is common terminal, and is to be used together with PE or other terminals, in this case, we will use PE terminal.

0V and 24V are power terminals, which will be used to draw power to our 202U receiver unit.

So the correct connection would be as follows.

0V and 24V ~ connect to our 202U’s power terminals.

COM and PE ~ connect to our 202U’s N/O and COM terminals in either relay group.

After that, you can test your door function using remote that is programmed into our SR-RCS-202U receiver unit, the door should work as expected.

Our SR-RCS-202U can be used pretty much on every garage door openers with push button or manual trigger terminals.
