Check item or cause
Is Communication Server 2 set for the
correct communication port
(COM1-COM10)?
Is some other product running that uses the
communication port?
Or is any permanent resident software
running that uses the communication port?
In the communications settings for this
software, is the communication method set
to TCP/IP or USB?
When Communication Server 2 is green (RS-232)
(2)
If Communications Server 2 is displayed green with communications with the robot controller set to RS-232,
check the following.
Check item or cause

The default value for this software is COM1. On some
computers, COM1 is not allocated to RS-232, but to an
infrared port, modem, or the like. Also, when using
RS-232 over USB, the port used for RS-232 may be
other than COM1.
Use the Windows device manager or the like to check
the COM number allocated to RS-232 and change the
"Port" setting in the communication settings to that port.
A computer communication port cannot be opened for
two applications, so either close the other application or
change the port that this software uses.
Change the communication method to RS-232.
The communication settings in this software and on the
robot controller must match.
The default protocol for this software is "Procedural", but
for CRn-500 series robot controllers, the default protocol
is "Non-Procedural"
