Serial Remote Radio Systems (Future Option)

5.3.1. General Description
The standard 12RII-SR radio is identical in operation to the 12RII-LC radio except that it is not mounted in the typical brake
stand enclosure. The Serial Remote Control Head that is used in conjunction with the 12RII-SR radio is mounted in the control
stand location. The radio is mounted in a locker or in the nose of the engine. A Serial Interface Cable is used to connect the
radio to the control head.
Optionally the radio supports the connection of a second control head on J8 and a radio handset at J2. Program connector J3 is
also standard as on the other radio systems.
