General Description
8-pin bulkhead connector for receiving navigation
data.
This connector is internally wired to a 9-pin DSUB
connector that connects to the COM1 connector of
the Demultiplexer board and to the output of the
12 VDC power supply.
3-pin bulkhead connector that connects to either a
115 or 230 VAC, 50–60 Hz power source.
6-pin bulkhead connector that connects to a
12 VDC, 1.5 A power source
Green indicator that is illuminated when either AC
or DC power is on.
3-position switch that when switched to VAC,
selects AC power to power the TPU, and when
switched to 12 VDC, selects DC power to power the
TPU. Power is applied in accordance with the
RUN/STAND BY switch position. With the switch
in the center position, the power is off.
2-position switch that when switched to STAND BY,
powers the wireless router so it can establish
communications with the computer after switching
the VAC/12 VDC switch from off to VAC or
12 VDC. When switched to RUN, after
communications have been established, applies
power to the rest of the components in the TPU. This
switch should be in the STAND BY position when
the VAC/12 VDC switch is switched from off to
VAC or 12 VDC.
Slide switch which selects 115 or 230 VAC
operation. This switch is located inside the TPU and
is shown in Figure 6-6. (See CAUTIONS on
page 6-10 regarding the use of this switch.) The
switch positions are 115V and 230V for 115 VAC
and 230 VAC operation. The displayed number is
the selected voltage.
