2.2.8.2 TRIGGER OUT
A synchronization cable is provided (4450BA0079) for Trigger In, Trigger_Out1 and /Trigger_Out1.
See Figure 2-10. The TRIGGER out consists of a positive going TTL pulse on one BNC and a nega-
tive going TTL pulse on another. By using both positive and negative signals, a differential TTL-
compatible pulse, occurring at the time of interrogation for a transponder or a responder, is availa-
ble. This TRIGGER out pulse is present simultaneously with the leading edge of each interrogation
pulse. The output can be configured as differential or positive / negative single ended when used
with the COMMON line. See Figure 2-13. The Trigger_Out4 and /Trigger_Out4 can be programmed
within the Peripheral Interface Card to either output a trigger or connect it to GND. The Gnd con-
nection can then be used to reference any of the pos or neg triggers for single ended operation.
Jumper JP15 from 1-2 for Trigger_Out4 or 2-3 for GND. Jumper JP18 from 1-2 to output
/Trigger_Out4 or 2-3 for GND.
2.2.9 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. An interface cable is provided,
4410BA0123, for inputting analog pitch and roll sensors to the BATS. See Figure 2-15 for
connections and 2-16 for the 4410AB0123 cable Assembly. The mating connector is a MS3106B-
24-5S from Amphenol. The 4760B MRU uses this interface to provide +12VDC to the unit while the
RS232 connects to COM #3.
