I'm a bit puzzled and could use some help. I'm currently a 10 year RF Transmission System technician in the USAF. I need to tie in a PRC-113 Radio using the audio port on the radio to a switch. Basically what I'm attempting to do is take a 250 handset and womp off the handset and solder or splice on some wire I can crimp into an RJ45 connector to plug into my switch. I've found the pin out for the handsets connector but I'm unsure how that correlates to the color code I need to put in my RJ45. I've found the cable I need online but I'd like to test my theory before I spend the funds on a good idea. Any help would be greatly appreciated!

To anyone looking to acquire commercial radio programming software:
Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.
If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.
To obtain Motorola software see the Sticky in the Motorola forum.
The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.
For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).
This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.
PRC Radio tie in to LMR system

Short of a few very specific network devices that will accept E&M/Wireline signalling and encapsulate the audio into data packets, you cannot just simply connect recovered audio output and feed it into a standard ethernet port on most devices.
What "switch" are you planning to plug this proposed RJ45 adapter into?

It's called a CCGW. It was previously working using the data port on a newer PRC Radio but that Radio isn't operating correctly now. The cable that was used before came out of the data port and was wired into this box and then a standard RJ45 was plugged into it and the other end of the switch.

Are you working with a Motorola MCC7500?
This particular spec in the document stands out: “Each MCC 7500 CCGW router provides four RJ45 connector ports for interfacing to analog conventional base stations.”
So I think you are on the right track! Wait a bit for some Moto folks to pop in here and if they don’t, maybe a mod can move this to the Moto section once you confirm that you are indeed using an MCC7500.

Edit: if you have the documentation, the pinout will absolutely be somewhere in there, since these are for generic interfacing to analog equipment.

Rather than cutting off an H-250 handset and using that wiring it would be better to buy a new or used U-229 audio connector off eBay cheap then cut a connector off an RJ-45 shielded patch cable and solder that to the U-229. The wiring inside an H-250 is a b*tch to deal with and solder. Here is a brand new U-229 for a fraction of its original cost.
I find it interesting you guys are still using the PRC-113, those are getting quite old. But once you get the cable made up it should work with an MBITR or PRC-152, but the Harris can have a mic bias voltage that you should be aware of.

Here's the pinout for the CCGW analog radio port. Note that COR is optional, the CCGW can be programmed for VOX (voice activated channel activity). However if you plan to do patching on the console COR is preferred over VOX.
LMR/console techs refer to these as CCGW's or gateways, calling it a 'switch' will create confusion.

The CCGW model appears to be a S2500. Its super old.
Thank you for diagram on the CCGW, that will be very helpful!
That will probably be the best option to be honest. Yeah, the 113 is super old. We've got a bunch of them that just sit around in a vidmar so when the other radio went bad we tried to find a solution to get this back up and running. We spoke with a Harris rep and they suggested we try this option in the mean time.Rather than cutting off an H-250 handset and using that wiring it would be better to buy a new or used U-229 audio connector off eBay cheap then cut a connector off an RJ-45 shielded patch cable and solder that to the U-229.

What model was the old radio? I suspect it was likely not using E&M if connected to a data port, and the CCGW will need to have the port reconfigured to support analog signalling. Potentially needing to use a different port on the CCGW altogether depending on the model.
KF8YK is correct, calling this device a switch will lead to confusion by anyone that can potentially help. The schematic they posted is correct for connecting a 4W device with COR and PTT to one of the E&M ports.

The CCGW diagram assumes the radio provides a balanced input and output but most PRC type military radios are unbalanced for both speaker and mic. The PTT switching in many military radios is also sinking 24V to ground. Here are some typical pinouts for a 5 or 6 pin military handset connector.

The old radio was a 117F. I don't personally manage the CCGW so I'll have to get with the Motorola technician to go over the specific port configurations. Sorry to miss label that piece of equipment, lately I've only worked with more modern radio systems that were IP based and I plugged straight into a Cisco switch/router and moved it through the network on a VLAN. With me not being able to manage the Motorola stuff I don't fully understand the network scheme. I remember him mentioned that it wasn't set to COR and we could try that but I didn't want to introduce to many factors into our trouble shooting at that moment.
This is more so the break out I've been looking for. Thank you, this actually describes everything on the pins.
I suspect the 'data' port on the PRC is more like the 'accessory' connector on a LMR radio, i.e. a collection of signals for a wide array of peripherals and applications.
The data port on a S2500 CCGW would only connect to a P25 Motorola base/repeater using Moto's proprietary v.24 serial protocol.
I've connected the unbalanced audio from XTL mobiles radios directly into a CCGW by connecting the ring side of the balanced lines to the mobile radio ground pin, audio sounds fine. Just don't expect to run hundreds of feet of wire, a few feet at most.
The E&M ports in the CCGW are repurposed telephone cards and they'll easily tolerate 48 volts.
It was my understanding that a lot of command posts went to OpenScape Xpert. I never saw one with a Motorola console. Even if you don't have to go a long distance, using a RoIP solution like Cubic/Vocality makes life so much easier when interfacing to various radios. Even the Raytheon/JPS units have interface cables for the PRC-113 and 117.
Something like this?

Yeah, that's the cable I need but I'm trying to iron out the pinout so I can confirm my theory before I use military funds to purchase itSomething like this?

Sorry, late to the party. Don't you have a JISCC you can rogue a cable from before you go cutting stuff?
