Checking the Communications with the Support Tool/Host
Execute a NT600S-to-support tool/Host communication check by the menu op-
eration from the System Menu as mentioned below.
This check can be executed only for RS-232C communications.
In direct connection other than the C200H communications, the same connector is
used for the connection of a support tool and the Host. To execute communication
check with the support tool, if the Host is connected to the NT600S, first discon-
nect the cable that connects the Host and connect the support tool to the same
connector. Execute the check after that.
