System Maintenance
Checking the Communications with PC
106
Execute a NT30/30C-to-PC communication check by the menu operation from
the System Menu shown below.
The NT30/30C uses the same connector for connection to the NT-series Support
Tool and RS-232C connection to the PC. To establish an RS-232C connection
with the PC, disconnect the cable from the NT-series Support Tool and connect it
to the PC: the communication check can then be performed.
