KVL 3000/4000 Keyload Interface Cables and Adapters
Most Motorola military and law enforcement 2-way radio communications uses an encrypted algorithm for secure voice messages. The encryption key is inserted in the radio using a KVL 3000 or KVL 4000 as shown. The basic interface cable is the Motorola TKN8531 and an adapter specific to the radio model. XTS 5000/2500 series portable hand-held radios require a NTN8613 adapter. APX 7500/6500 and most XTL 5000/2500 mobile radios need the HKN6182.
APX 7000/6000 series use the WPLN6904 cable that does not require an adapter.
OTAR and Radio Authentication Cables
For systems using OTAR (over-the-air-rekeying) or radio authentication, the KVL uses a different set of cables without the need for adapters. APX, XTL, and Astro Spectra mobile radios use the HKN6183. XTS portable radios require the RKN4106 and APX 7000/6000 portables use the WPLN6905 cable.
