Quantar mute via wildcard

Is there a command in the Quantar wildcard tables that will mute the RX audio to the local mike jack?

I want to set up a wildcard that on wireline ptt will mute the local audio then do a PTT.

I have the expanded TRC board and normaly operate it as 4 wire, looking to plug a 2 wire tone remote adapter into the local jack and run it to a backup console. I need to mute the local jack to prevent the 2 consoles from feeding back, I could X mute the consoles but am trying to avoid this as I have found that if I powerthe main console (4wire) down for maintenance the X mute line to the backup (2wire) console gets pulled low and causes a mute.

After thought: can the 4 wire expanded TRC be set up as 2 wire on the unused line ports, I would then have a 4 wire connection and a 2 wire connection, if this is possiable would the 2 wire connection hear the 4 wire xmit. If it does I again have a feedback problem

That's best done with a LOTL (line operated transmit light) circuit in the console or remote control aka poor man's crossmute. Upon detection of 2175 it lights the transmit indicator and mutes the local speaker.

I could to it that way but I am trying to avoid hardware mods, would rather do it in software at the station.

Playing with the Quantar software today I did find a command MRTI disable and MRTI enable, If this mutes the station audio to the MRTI connector I could build a wildcard table to disable the MRTI on LINE PTT put my second console in there.

I did not find any commands that look like they would mute local rx audio to the mike jack.

Will have to check out how the MRTI works next time I am on site.
