If I want to connect more than 1pc CR1000(for example 2 pcs) to PC, and use Loggernet, could I connect as follow
PC(Com1)<---RS232--->CR1000(Pakbus address=1)<-----CSI/O Line--->CR1000(Pakbus address=2), please advise...
Using CS I/O to CS I/O connections can be done but requires external interfaces and null modem cables, primarily to generate the ring signals that the CSI/O port needs.
A simpler solution is to connect the dataloggers via the control port serial ports (effectively a 3-wire connection between loggers; TX to RX X 2 plus G to G). The serial ports will need their baud rate set in the logger settings and the first logger to be set as a router.
The official, more flexible solution is to set up an MD485 network which amongst other things allows much longer cable lengths.
