Genesis and EF Johnson Technologies® have developed an RF-modem solution for P25 (9600). The EFJ53SL radio extracts the 9600 CAI as well as the 3600 Control Channel, making it a unique radio that can handle both.

As P25 (9600) systems professionals, we have expertise in ordering and programming the EFJ 53SL Radio as a replacemet for the MCS2000 for 3600 systems. This means that all Genesis' RF-based products (GenWatch3®, GEnSAC and GenSPOut) integrate very nicely with the EFJ 53SL. Furthermore, this radio allows smooth migration from 3600 to P25 for the aforementioned products.

Connections to the EF Johnson Radios

Each EFJ5300 Series radio includes the Topaz interface, a TCIP/IP protocol. Genesis is among a handful of companies licensed to implement this protocol. Topaz allows us simple access to the CAI and Control Channel to receive OSP and OSW data. We can also create and send ISW data. However, we cannot send ISP data, due to a restriction in the P25 CAI protocol.

Our Triage Guide helps customers diagnose connection issues between GenWatch3 and the EF Johnson 5300 Series mobile radios. GenWatch3 relies on a 3-step process to receive data from the EF Johnson 53SL Mobile Radio:

  1. Receiving Control Channel data
  2. Transmitting data to the GenWatch3 Host
  3. GenWatch3 settings and license restrictions
