Kenwood NX-5800 to NXU-2A

[SummerDays64]

I have read many threads on this forum, and there seems to be some great people that are knowledgeable. I am hoping someone can help me with some information. I have gotten myself a Kenwood NX-5800 and a JPS NXU-2A. My plan was to hook them up together and use them on Zello. My hunting cabin doesn't have cell service, but I do have a UHF licensed base radio. My wife doesn't like to carry a radio but wants to know I am safe each night after hunts and prospecting. The NXU and NX-5800 will remain at home. We already use radios from time to time so coverage there isn't an issue, she just doesn't want to carry a radio to the store and errands, but she does take her cell phone.

I am just looking for a little help with the pin assignments on the radio and NXU. I do have a cops of the software for the Kenwood and cable so I am good there. I just need to make the physical connections but do want to hook it up wrong.

Thanks

I have to dig in to my archives, but there's a pre-made cable that can be ordered for it, that goes to the db25 and mic jack.

The pinouts for the DB25 are in the service manual. I have some application notes for cables I've built for VM5000s; the hardware is identical. I'll check when I get home tonight.

Are you talking about the $375 cable from JPS? I would rather roll my own than pay that, just need some help with what pins connect to each other.

Easy enough...

KWD DB25 NXU DB15

6_______________6________Audio out from NXU, add 22k series resistor between the two
25_____________14_______Audio out ground (balanced line)
17_____________8________Audio in to NXU. Set NXU for unbalanced line
24_____________12_______PTT. Program 5800 AIO#1 as input Ext PTT
23_____________13_______COR. Program 5800 AIO#2 as output TOR
7, 11, 18_______1, 7______Ground. Your choice of pin
