20.1.1 Connecting Troubleshooting Checklist

Programming and debugging can use MJ2 if it is set as the default programming port.
2.

3.
Assure that the correct COM port is selected in Cscape.

4.
Check that a Loaded Protocol or ladder is not actively using MJ1/MJ2. Taking the
controller out of run mode from the System Menu on the controller will make MJ1/MJ2
available to Cscape.
5.
Make sure the COM port of the PC is functioning. An RS-232 serial loopback and
Microsoft HyperTerminal can determine positively if the COM port is working. Or connect
to an alternate device to determine if the port is working.
6.
Successful communications with USB-to-serial adapters vary. If in doubt, Horner APG
offers a USB to serial adapter. Part number: HE-XCK.
7.
XLE/XLT units with built-in Ethernet or installed HE-XEC module can be programmed
and debugged via the Ethernet port. If the HE-XEC is installed, it can be selected as the
programming port. The selection is made in the controller's System Menu under the
Serial Port settings. If there are difficulties connecting, make sure that the default
programming port is set correctly with the connection method being attempted.
