Setting up and Connecting the Splashproof TPU
Setting up and connecting the Splashproof TPU is similar to that of the rack mount
TPU as described in APPENDIX D: “General Setup, Configuration and
Troubleshooting.” However, the power connections are different. In addition,
because the LAN connector is internally wired through a crossover block to the
LAN connector of the CPU board, a crossover cable (not supplied) is required
instead of the supplied waterproof LAN cable when connecting the TPU to a local
area network using a hub or switch. Therefore, when connecting to a hub or
switch, connect a crossover cable to the LAN connector on the TPU and to the hub
or switch. When connecting directly to a computer, connect the supplied
waterproof LAN cable to the LAN connector on the TPU and to the computer.
6.2.1 Included Accessories
The following accessories are included with the Splashproof TPU:
• AC power cord
• DC power cord
• Towfish jumper cable
• GPS connector
• TRIG connector
• Waterproof LAN cable
6.2.2 Connecting Power
The TPU can be powered from a 115 VAC, 230 VAC or 12 VDC power source.
However, before making any power connections, refer to the CAUTIONS below.
To open the TPU, lay it on a flat surface with the connector panel to your left. The
connector labels will be upside down. Then release the two latches and carefully
open the cover.
CAUTION
When powering the TPU from a 12 VDC power source, be sure
the VOLTAGE SELECT switch inside the TPU is switched to 115V. Failure
to do so will not provide the required 200 VDC to power the towfish. The
VOLTAGE SELECT switch is shown in Figure 6-5 on page 6-5.
CAUTION
Do not power the TPU from a 230 VAC power source if the
VOLTAGE SELECT switch inside the TPU is switched to 115V. This switch
must be switched to 230V before powering the TPU from a 230 VAC power
source. Failure to do so may damage both the TPU and the towfish. The VOLTAGE
SELECT switch is shown in Figure 6-5 on page 6-5.
