3.7 Power Connection and Wiring
There is no ON/OFF switch on the Lynx. As soon as power
is applied, the equipment will be operational. This means
that there can be up to 1W of RF power present at the
antenna port. The antenna port should be terminated
before power is applied.
Power is connected using the DC power plug contained in the Accessory Kit. Use Table 3-A or 3-B
along with the associated diagram of Figure 3-7 or 3-8 to connect the DC power cables. For
example, for a negative DC power input, use Table 3-A and Figure 3-7.

Pins 1 and 6 are connected together on the motherboard. Either
pin may be used to apply (-DC) DC power input. Similarly, pins 3
and 4 are connected together on the motherboard and may be
used to apply (+DC) DC power input.
For DC power return connection, connect to the opposite voltage
(either the -DC or the +DC Pin) and connect the return to ground
at the DC power plug on pins 2 and/or 5.
