BATS AND PORTABLE BATS INSTALLATION

2.3.7.1 INPUT TRIGGER
The Transceiver can be externally triggered via the “SYNC” connector located on the side panel of
the Portable unit. A synchronization cable is provided (4450BA0165) for Trigger In and
/Trigger_Out1. See Figure 2-22. This can be connected between an external key source (trigger
source can range from TTL to +15V) and the BATS Transceiver. Connect the external trigger be-
tween the TRIG-IN1-LO and the TRIG-IN1-HI
3
. The external trigger for Target #1 becomes the
master for all other targets when in this mode. All other targets switch to external mode, (via
Trackman Software) synching from the trigger #1’s source. Set the Trigger edge that you want to
trigger the unit with in the Trackman Software. See section 3.
2.3.7.2 TRIGGER OUT (NEG)
A synchronization cable is provided (4450BA0165) for Trigger In and /Trigger_Out1. See Figure 2-
22. The TRIGGER out is a negative going TTL pulse occurring at the time of interrogation for a
transponder or a responder. This TRIGGER out pulse is present simultaneously with the leading
edge of each interrogation pulse.
2.3.8 PORTABLE BATS - ANALOG SENSOR INTERFACE
The ANALOG input connector allows input of an analog signal from a compass, dynamic motion
sensing system, (analog pitch and roll signals from an external sensor such as the EdgeTech Model
4414B), and also the depth signal from an underwater vehicle. For the Analog Input connections
see Figure 2-23. An interface cable is provided, see Figure 2-24, 4450BA0166, for inputting analog
pitch and roll sensors to the BATS. The 4760B MRU uses this interface to provide +12VDC to the
unit while the RS232 connects to COM #3.
2.3.8.1 DEPTH INPUTS
The analog output voltage from a depth sensor (typically located on a vehicle being tracked) con-
nects to the ANALOG input connector located on the rear panel of the Transceiver. See Figure 2-19.
The BATS converts this analog voltage (0 - 6 VDC maximum) to a target depth.
2.3.8.2 ANALOG COMPASS INPUT
The analog output voltage from a compass (0 - 6 VDC maximum) connects to the COMPASS input
of the ANALOG connector. See Figure 2-23. The BATS converts this analog voltage to a vessel
heading in degrees.

NOTE: The REMOTE-IN trigger is optically coupled.
