nominal power supply.
 33MHz CPU with Ethernet: Supports +12Vdc nominal or +24Vdc
nominal power supply.
Alternatively, you can power low powered versions of the ControlWave
Express using a solar panel connected to a user-supplied rechargeable
7AH (6V/12V) lead acid battery at connections TB1-1 and TB1-2.
TB1 connections are:
 TB1-1: (Solar Power IN+): Power from a 1W – 6V, 5W – 6V or
5W – 12V solar panel (internally wired to recharge a user-supplied
battery). Not available on units with Ethernet.
 TB1-2 = Ground (GND)
 TB1-3 = Primary Power: Power from a user-supplied nominal
+6Vdc , +12Vdc or +24Vdc power supply, depending upon the
CPU type.
 TB1-4 = Ground (GND)
 TB1-5 = Auxiliary Power Out+: for an external radio or modem (if
supported). Not available on units with Ethernet.
 TB1-6 = Ground (GND) for Aux power out.
