This custom interface cable connects the Retevis RT97S portable repeater's DB9 port and a DMK URIxB USB radio interface (not included). This allows for controlling the repeater from a PC or Raspberry Pi.
The cable allows you to connect your repeater to a URIxB on a Raspberry Pi connected to the myGMRS Network or any other repeater controller or linking systems that use a PC or single-board computer.
This cable is 2 ft. long (61 cm), and contains metal RF-shielded DSUB connectors on both ends, flexible shielded cable, and thumbscrews for secure attachment.
Retevis RT97S to DMK URIxB Custom Interface Cable out of the box failed to work. Once connected - I rebooted the mygmrs node, and the radio keyed once. Any tones transmitted over the repeater do not activate any functions. The repeater operates in the local mode with no issue, maybe I miss understood the purpose of the cable with the RT97S. The cable appears to be very robust. I will be placing my other repeater back online to see if it functions differently.
