    Manual revision 019 Section 2: Description of MicroCAT SBE 37-SMP RS-232 External Power The MicroCAT can be powered from an external source that supplies 0.25 Amps at 9-24 VDC. The internal lithium pack is diode-OR’d with the external source, so power is drawn from whichever voltage source is higher. The MicroCAT can also be operated from the external supply without having the lithium batteries installed.
