NAV:
DB9 female connector that is used to input
navigation data from a navigation device using the
navigation cable pigtail.
1PPS:
BNC connector that is used to input a 1PPS time
reference signal from a navigation device or time
reference unit.
120/240VAC:
3-pin bulkhead connector that connects to a
120 or 240 VAC, 50–60Hz power source using the
AC power cord.
24VDC:
2-pin bulkhead connector that connects to a 24 VDC
power source.
For the connector pinouts and pin orientations for each of the connectors on the
TIU side panels, refer to Table 3-2 through Table 3-6 on page 3-8.
To connect the system components:
1.
Connect the deck cable to the T/F connector on the TIU and to the jumper
cable on the Sonar Head Unit.
2.
If connecting a navigation system to the TIU, connect the navigation cable pigtail
to the NAV connector of the TIU, and then connect the pigtail wires to the
navigation system’s RS-232 serial port as follows:
• Connect the wire labeled "GPS Tx" to "Tx."
• Connect the wire labeled "GPS Rx" to "Rx."
• Connect the wire labeled "GND" to ground.
3.
If desired, connect a 1PPS time reference unit to the 1PPS connector using a BNC
cable.
4.
Connect the LAN cable to the LAN connector of the TIU and to the Ethernet
port of the PC.
5.
Connect the AC power cord to the 120/240VAC connector of the TIU and to a
120 or 240 VAC, 50–60Hz power source, or connect the DC power cord to the
24VDC connector and to a 24 VDC power source.
WARNING
Before connecting the deck cable, verify that the TIU AC
power cord is disconnected from the power source. Failure to follow this
practice may result in personal injury or damage to the Sonar Head Unit or
the TIU electronics, or to both.
NOTE
If connecting a navigation system to the TIU, it must have an
RS-232 interface that outputs a NMEA 0183 message string and be
configured for GGA&VTG, GLL&VTG or RMC at 4800 baud.
