COM220 modem & RS232 port


Spyros Apr 5, 2018 06:11 AM

I am trying to use a COM220 modem with a CR300 D/L (or RS232 port of a CR1000),but until now i have no success.

Has anyone else try this?

Sorry Spyros, the COM220 does not work with the CR300. On the CR1000, you will need to connect the COM220 to the datalogger using the CR1000's CS I/O port instead of the RS232 port.

See section 3 of the COM220 manual for details (https://s.campbellsci.com/documents/us/manuals/com220.pdf).

Dear Gary,

i know i can connect it to CS I/O port of Dataloggers.

I was meaning to connect COM220 with RS232 port using an interface e.g. SC105.

Is this possible?

Thanks in advance

No. It is not possible.
