A.1.1 Point to Point Protocol (PPP) Communications (optional)
In PPP mode, the modem assigns the datalogger an IP address by means of a
serial connection. This allows access to the datalogger’s IP capabilities without
requiring an Ethernet peripheral. The modem’s COM1/Data port must be used
for a PPP connection. In order for the PPP to function properly, both the
modem and datalogger need to be configured. The physical connection for PPP
communications requires the use of a null modem cable to connect the
dataloggger’s RS-232 to the modem’s RS-232 port.
