as heat buildup could occur and viewing the LCD monitor and status indicators could be difficult. The
location should also enable direct communications with the deck crew that is handling the tow vehicle.
Secure the rack mount topside in place, using tie-downs if necessary, near the required AC power source.
If you are mounting the 3200-XS Topside Processor and the Power Amplifier in a 19-inch rack other than
the supplied rack mount enclosure, ensure that there is ample room behind the rack for connecting the
cables. Support the components inside the rack using appropriate mounting brackets and secure the front
panels using standard 19-inch rack front panel mounting hardware.
3.4.1 Rack Mount Controls and Indicators
The Rack Mount includes controls and indicators on the front and back as shown in FIGURE 3-1 and FIGURE
3-2. Several test points are also provided for voltage measurements. The Rack Mount controls and
indicators are the following:
POWER SUPPLY: Rocker switch. Turns on the power supply in the 3200-XS Topside
Processor. This switch can be left in the on position at all times.
SYSTEM POWER: Push button toggle switch. Turns on 3200-XS Topside Processor.
POWER: Blue indicator lights up when amplifier is on.
RESET: Momentary Push-button switch. Resets 3200-XS Topside
Processor.
HARD DISK: Red indicator. Indicates the 3200-XS Topside hard drive is active.
SYSTEM: Green indicator. Illuminates when 3200-XS Topside is on.
READY: Green indicators. Illuminates when system ready to transmit.
Upon power up, wait one to two minutes for indicator to
illuminate.
12 VDC OUT TO PREAMP: Test point. Measures 12 VDC voltage applied to preamplifier on
the tow vehicle.
TOWFISH PREAMP 5 VDC: Test point. Measures 5 VDC voltage preamplifier feedback
voltage from the tow vehicle.
PREAMP COMMON: Test point. Common ground for the preamplifier -5 VDC and 12
VDC test points.
GND: System ground connection.
DATA: Amp Indicator lights up and blinks when data is being transmitted
CH1 & 2: Defunct dials on the amplifier. Turning these will not affect
