J4 Output connector
The J4 Output connector provides the conditioned sensor outputs that can be
connected to a data acquisition or test control system.
J2A Shunt A
J2B Shunt B
connectors
The J2 connectors are used for the shunt cables. The shunt cables are connected
to the two 6-pin shunt cal connectors on the front of the transducer.
Comm In
Comm In is an 8-pin modular phone jack connector (RJ-45) that provides a
connection to an RS-232/RS-485 remote host, or to another Low-Profile TI in an
RS-485 multidrop communications chain. The cable connected to Comm In
selects an RS-232 or RS-485 interface. The RS-232/RS-485 interfaces on Comm
In are electrically isolated from the Low-Profile TI power. This connection is
only needed when you are downloading new settings to the Low-Profile TI
module.
Under normal operating conditions, no host connection is required. The Comm
In and Comm Out connectors allow you to daisy-chain multiple boxes without
Y cables or multiple connections to the host computer.
Comm Out
Comm Out is an 8-pin modular phone jack connector (RJ-45) that provides a
connection to another Low-Profile TI chassis in an RS-485 multidrop
communication chain.
J3 Power connector
Connect a power cable from an external 12 V DC source.
Ground Terminals
The ground terminals enable you to ground the Low-Profile TI, and chain several
Low-Profile TI boxes together.
Slip ring daughter
board
A slip ring daughter board must be installed in the Low-Profile TI when a
SWIFT transducer with a slip ring will be mounted on the vehicle
Transducer connector
Connect the data cable from the transducer slip ring to the Transducer Connector.
