The field housing contains the signal processing system (Figure B-23). The
housing contains all signal processing boards, the battery supply, and avail-
able options – a modem for telemetry, solid state memory for stand alone
operation, and IS zener diode barriers. An RS-422 and 232 serial interface
is standard, as is a 4 line by 16 character LCD for quick determination of
the system's status. The field housing is compliant with IP 67 (equivalent
to NEMA 6P) and is suitable for mounting in a manhole.
