APX Crosspatching between two APX 7500's

[ExpatLMRGuy]

Hello all!

Does anybody know if there is a way to utilize a crosspatch cable for the respective rear consolette crosspatch port to do the following:

Patch voice communications from Zone A; Channel 1 to Zone B; Channel 1.

I am trying to set it up so that if a subscriber transmits on Z-A Ch1 it can be heard on Zone B Channel 1 (and vice versa).

Potential Limiting Factors:

Zone A Ch.1 is on a different trunking system and encryption key, however both sites have been programmed to work on the individual subscribers' radios.
(Think of Zone A being the Primary and Zone B being a backup).

Zone A coverage does not provide the capability to communicate indoors due to proximity of the tower location however, Zone B does provide the capability to communicate indoors.

I am currently using CPS 20.0.0.3 software.

Thank you in advance!

Using usb type B port to access setting page, open google chrome and input http://192.168.144.1:8801/

You can find the crosspatch setting.

Thank you! I have enabled it. However, I still am not able to achieve the intended result

Do you have a menu button to turn it on and off ?

 

[ExpatLMRGuy]

Yes, I do have the menu button. I will share photos tomorrow.

However, I can visually verify that the crosspatch is enabled on the display and when I key up, I see a series of bars on the top of the display screen, indicating the transmission is being broadcasted. It's just not being picked up on the other radio which is connected via the crosspatch port.

I was using a crossover cable, and just found an actual motorola crosspatch cable at home. So I will test that tomorrow also. Maybe it's just a bad RJ45?

If this solution doesn't work, I'll probably end up going a more technical route and tie this into the CCGW, then create a resource in the MCC7500 and patch it to the intended talkgorup

If you looked at the pinout in the manual it is not a standard cross over cable. Its a special cable. We normally make these on site. Also make sure you are not decensing the radios or casuing issues with unshielded cables and stray RF. One customer had both of his on mag mounts above the rack. Didnt' work at all. Moved to outside antenna and all was well.

Thanks for the pinout, I ended up finding this as well as a cable which was previously fabricated by someone at Motorola.

I've quadruple checked everything and still no joy.

At this point, I'm considering running the APX directly into our CCGW and then patching it over from conventional to trunking.... another challenge

The crosspatch cable I made did not work either. Regardless of the consolette settings being properly enabled. It does not seem that this method will work. I'm thinking that maybe this is an additional featureset of Motorola that needs to be purchased?

No its part of the software. If its set on both radios and enabled via softkey it should work. Have done it plenty of times. What are you seeing/hearing ?

You could grab an adapter and check the signal of each wire with a VOM and TIMS set. Its pretty basic - COR-PTT, RX -TX audio
