SRT CR91

Good evening
I hope I'm on the right forum, I have a question related to my SRT CR91 receiver, I would like to use this device coupled to a transmitter but I don't know how to manage the mute on the receiver.
Thank you in advance for your reply.

You have two options for hardware muting of the receiver,

The first is to use pins 6 and 3 on the 9-pin connector X2 on the connection board A11. A positive voltage on pin 6 will mute the receiver. The other is to pull down pin 3 on the 25 pin connector X3 to ground potential pin 1.

There are also software muting commands that may be sent to the receiver in remote control mode,
ASCII < (hex 3C) will mute the receiver and ASCII > (hex 3E) will unmute it.
