17.1.1 Connecting Troubleshooting Checklist (Serial Port – MJ1/MJ2 Programming)
1. Programming and debugging must use MJ1/MJ2 or use Mini B USB.
2. Controller must be powered up.
3. Assure that the correct COM port is selected in Cscape.
Tools / Editor Options / Communications Port.
4. Assure that a straight through (non null modem) serial cable is being used between PC and
controller.
5. Check that a Loaded Protocol or ladder is not actively using MJ1. Taking the controller out of run
mode from the System Menu on the controller will make MJ1 available to Cscape.
6. Make sure the COM port of the PC is functioning. An RS-232 serial loop back 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.
7. Successful communications with USB-to-serial adapters vary. If in doubt, Horner APG offers a
USB to serial adapter. Part number HE500USB600.
17.1.2 Connecting Troubleshooting Checklist (USB Port - Mini B Programming)
1. Programming and debugging must use Mini B USB Port or MJ1/MJ2.
2. Controller must be powered up.
3. Assure that the correct COM port is selected in Cscape: Tools/Editor Options/Communications
Port
4. Be sure that the USB cable is connected between the PC and controller and check the Windows
Device Manager to find out if the USB driver is properly installed and which port it set itself up on.
5. Make sure the USB port of the PC is functioning and/or connect to an alternate device to
determine if the port is working.
6. QX351 units without Ethernet must use the Mini B USB Port or MJ1 for programming and
debugging. If Ethernet is installed it can be selected as the programming port. The selection is
made in the controller's System Menu. If there are difficulties connecting, make sure that the
default programming port is set correctly with the connection method being attempted.
17.1.3 Connecting Troubleshooting Checklist (Ethernet port Programming)
1. Programming and debugging must use MJ1 or Ethernet Port.
2. Controller must be powered up.
3. Ensure that correct IP address is given in the Ethernet field and correct Mode is selected, in
Cscape: Tools/Editor Options/Communications Port
4. Ensure that the Ethernet Cable is connected between the controller and the Ethernet Hub.
Make sure the Ethernet cable is functioning properly
