3.14 JS-901-xx and JS-902-xx Jump Seat Station with Expansion Port
3.15 JS-901W-xx and JS-902W-xx Weatherproof Jump Seat Station with Expansion Port
3.16 JSDB-902-10-30 Jump Seat Distribution Box with Tailboard Expansion Port
The JS-901-xx Jump Seat Station with Expansion Port is similar to
the JS-900-xx with the addition of an expansion port. This allows
additional remote stations to be daisy-chained together. The standard
JS-900-xx, another JS-901-xx, or a JS-902-xx for adding a tailboard
or tiller position can be plugged into the JS-901. No additional ports
are required at the master station and up to a total of eight headset
positions can be added in this manner. There are a variety of lengths
for the JS-900-xx, with xx denoting the length. The JS-902-xx Jump
Seat Station with Tailboard Expansion Port is identical in appearance
to the JS-901-xx, but it allows a TS-900 Tailboard Station to be
plugged in. If a series of stations are being daisy-chained to the
"REMOTE" port of the IM-900, the JS-902-xx is always the second-to-
last station in a chain of stations, with a tailboard becoming the last
station.
The JS-901W-xx Weatherproof Jump Seat Station with Expansion
Port is similar to the JS-900W-xx but adds an expansion port. This
allows additional remote stations to be daisy-chained together. The
standard JS-900W-xx, another JS-901W-xx, or a JS-902W-xx for
adding a tailboard or tiller position can be plugged into the JS-
901W-xx. No additional ports are required at the master station
and up to a total of eight headset positions can be added in this
manner. It is also possible to mix the JS-900-xx and the JS-900W-
xx variants. There are a variety of lengths for the JS-900-xx, with
xx denoting the length. The JS-902W-xx Jump Seat Station with
Tailboard Expansion Port is identical in appearance to the JS-
901W-xx. However, it allows a TS-900-xx Tailboard Station to be
plugged in. If a series of stations are being daisy-chained to the
"REMOTE" port of the IM-900, the JS-902-xx is always the second-
to-last station in a chain of stations, with a tailboard becoming the
last station.
The JSDB-902-10-30 is a single enclosure that provides
four jumpseat intercom-access/radio-listen headset
positions and a connection point for a TS-900 Tailboard
Station. The enclosure has four 20ft. unterminated
cables and one 20ft. cable terminated into a four-
conductor twist-lock connector that plugs into the
“REMOTES” port of the IM-900 or the “INTERCOM”
port of the IM-900E. Four Tip-Ring-Sleeve (TRS) panel
mount jacks are provided with this component and allow
the installer to mount the box in a remote or hidden
location and run the cabling to individual jumpseat
locations.
Note: Panel Mount Jacks must be isolated from chassis
ground
