6.1.3 External Connections
The external connections to the Splashproof TPU are made on the connector panel
which is shown in Figure 6-4. The connector panel is also shown inside the case
cover in Figure 6-5. Most of the connectors on this panel are wired to internal
connectors which connect to the Demultiplexer and CPU boards as shown in
Figure 6-6 on page 6-6. The external connections are the following:
TOWFISH: 8-pin bulkhead connector that connects to the
towfish using the towfish cable.
This connector is internally wired to a BNC
connector that connects to the 200 VDC power
supply. The power supply’s data output connector
connects to the CABLE connector of the
Demultiplexer board using a BNC cable.
LAN: RJ-45 connector that connects to the Ethernet port of
a computer.
This connector is internally wired to an RJ-45
connector that connects directly to the LAN
connector of the CPU board or to the optional
wireless router if installed. This router is shown in
Figure 6-5.
TRIG: 3-pin bulkhead connector that provides a trigger
output for keying external equipment.
This connector is internally wired to a BNC
connector that connects to the TRIG 1 connector of
the Demultiplexer board.
MAG OUT: 6-pin bulkhead connector that connects to a
magnetometer.
This connector is internally wired to a 9-pin DSUB
connector that connects to the COM2 connector of
the Demultiplexer board.
DEBUG: 3-pin bulkhead connector that connects to the serial
port of a computer and can be used to view and save
the boot sequence data using HyperTerminal.
This connector is internally wired to an RJ-45
connector that connects to the DBUG connector of
the CPU board.
