4. A100 Null Modem Adapter
The A100 has two 9-pin CS I/O ports with a null modem between them. The
ports are used to connect two 9-pin devices that would normally be connected
to the CS I/O port on a Campbell datalogger. The charger supplies 12 volts
and 5 volts to the appropriate pins on the connector for powering the connected
devices.
This cannot be used as a null modem between two RS-
232 devices.
