6) USB Port Connection
The TR400/OC400 terminal has a mini USB
data port to enable upgrading of the rmware,
advanced conguration, and data connection.
7) Connecting Power to the Terminal
The TR400/OC400 terminal can be powered from
the supplied AC Plug pack, or connect to an
external 10-32V DC power source.
ISD950 AC Plug Pack Installation
For installation using ISD950 110-240 AC plug pack,
connect the 4-way Microt connector from the plug
pack to the 4-way power connector on the rear of
the TR400/OC400 terminal. In this conguration the
ignition/accessory status is always ON.
DC Power Source Installation
The DC power cable has three wires, RED, BLACK
and YELLOW. The RED and BLACK wires are used
for the power connection while the YELLOW
wire can be connected to a vessel accessories,
ignition sense or other similar circuits to control
the ON/OFF status of the TR400/OC400 terminal in
synchronization with a vessel operation.
By default, the TR400/OC400 terminal will stay on for
20 minutes after this input (YELLOW wire) is switched
o. If a call is in progress while this occurs, the TR400/
OC400 terminal will stay on for 20 minutes after the
call is terminated. Please follow the steps below to
connect the DC power cable to the battery power
and the TR400/OC400 terminal.
1. Route the wire end of the DC power cable to
the connection point.
2. Connect the BLACK wire to the negative
terminal of the battery (10A fuse
recommended) or the vessel chassis (if
negatively grounded chassis).
3. Connect the RED wire to the positive
terminal of the battery. It is recommended to
add the 5A fuse (supplied) between them.
4. Connect the YELLOW wire to the vessel
accessory power. If the accessory power is
unavailable, this may be connected to a vessel
ignition voltage. It is recommended to add
a 1A fuse between them. The accessory wire
enables the TR400/OC400 to turn on and o
as the vessel key is enabled or disabled. If this
function is not required, the YELLOW wire
MUST be connected to the RED wire.
5. Connect the 4-way Microt connector on
the DC power cable to the 4-way power
connector on the rear of the TR400/OC400.
