C1221 - AC Power to Ethernet Hub/switch
An Ethernet Hub or switch is required if you need to use more
than one General Purpose Transceiver (GPT), or if you wish to
connect the echo sounder system to an existing network. Any
commercial 100 MHz Hub/switch may be used.

C1222 - Battery
This cable is used to connect a battery to the GPT.
The +12 Vdc input/output connectors can be used in the
following ways:
• Operate the transceiver from a +12 Vdc power supply.
• Operate the transceiver from mains power, but leave a battery
connected to the DC connectors. The battery will then
provide you with an uninterruptable power supply facility. It
will automatically be charged when the mains power is
present.
• Use the +12 Vdc power from the transceiver to power
external units.
