Technical Description

The COM220 has a CS I/O port, power terminals, screw terminals, and an RJ-11C jack. The datalogger connects with the CS I/O port via an SC12 or SC12R-6 cable. The RJ-11C jack is for attaching a surge-protected telephone line. Alternatively, the screw terminals (GND, RING, TIP) can be used to connect the COM220 with a phone line via a surge protector.
