The ES-900-xx and ES-900RA-xx Extension Stations extend
any Tip-Ring-Sleeve (TRS) connection to a remote location. It
can be used in radio access or intercom only locations. The
ES-900-xx and ES-900RA-xx are commonly used to remote
the Driver and Officer locations when the IM-900’s location is
hidden. They can also be used in jump seat locations where
obstacles in the compartment make it difficult for two
crewmembers to both plug into a dual jumpseat station. The
ES-900-xx and ES-900RA-xx are available in a wide range of
cable lengths, with xx indicating the length.
The RSJ-900RA-xx Remote Station Jack is used to remote
radio transmit headset jacks on System 900 Master Stations
(IM-900, IM-900E, MS-922, MS-922E); with xx indicating the
length. The extension cable is unterminated on one end to
allow easy installation of Panel Mount Jack (part number 21-
8004). The cable is terminated with a right angle Tip-Ring-
Sleeve (TRS) connector on the other end.
Note: Panel Mount Jack must be isolated from chassis ground
– Part number 21-8004 Jack includes isolating nylon washers.
The ES-907-xx Extension Station extends any Tip-Ring-
Sleeve (TRS) connection to a remote location with the
addition of a foot switch port.
