Cables to Provision AIE/E2E Keys
The following cables are used when provisioning the radio with encryption keys: PMKN4104_ - Active
Data Cable to provision the radio with Air interface encryption keys, and PMKN4108_ - KVL cable to
provision the radio with E2E keys.
The PMKN4104_ Active Data Cable provides a 5-wire RS232 interface (for example, RxD, TxD, CTS,
RTS, DTR) between a computer and a mobile radio. The cable has to be connected to the 26-pin
Accessory Connector on the rear side of the radio and into the 9-pin connector of a Data Device
(for example, PC, Laptop, console). The PMKN4104_ Active Data Cable is not repairable. Order a
replacement cable as necessary: Length: 2.0 m (6.56 ft).
