PakBus Overview

(p. 133).

The CR200(X) communicates with Campbell Scientific support software,

telecommunication peripherals, and other dataloggers via PakBus, a proprietary

network communications protocol. PakBus is a protocol similar in concept to IP

(Internet protocol). By using signatured data packets, PakBus increases the

number of communications and networking options available to the CR200(X).

Communication can occur via RS-232 or RF.
