BK IP Remote Head = BK Anywhere

In this video I demonstrate how you can take a BK M-150 Mobile Radio and convert the remote head control cable to an IP ethernet based transport system. This allows you to use the radio from anywhere you can get an IP connection with a LAN/WAN/VPN.
The audio bridge is handled by a pair of Telex IP-223's. The RS485 bridge is handled with a pair of PUSR USR-TCP232-304's. Power control is done locally at the head.
The radio can handle 2 each control heads, that would work in parallel, if desired. It can also be connected via WiFi off the LAN.
A 3ft micro-d9 to DB9 cable is available from Digikey for $25. Part number WM-3567-ND
