The largest area of difficulty in getting crWebBB up and running relates to serial communications problems - the application is getting no information from the host DCS or Maestro system.
Serial Trouble Shooting Steps
Here are some basic troubleshooting steps you can take to correct the problem:
| 1. | Check to be sure that you have a working cable connected between the crWebBB machine and the DCS or Maestro unit. This cable must be configured as a null-modem cable. See the section on serial interface for details on wiring pin-outs for the serial cable. |
| 2. | Ensure that you have selected a valid, working serial port on the PC on which crWebBB is running. There should be no other devices using the same port. A common example would be an internal modem using the same port number as a serial port that appears on the exterior of the PC, but is not enabled. You may also have inadvertently chosen the modem port instead of the available serial port on two-port machines. Use the [Select COM Port] button in the crWebBB preferences display to select a port. This dialog interrogates the PC and returns only valid ports. |
| 3. | Ensure that the serial port you've selected on the DCS or Maestro unit is a valid, working port. |
| 4. | Check the host DCS or Maestro configuration to be sure you've set up the machine properly for serial communications. See the section on Setting Up DCS for more information, or consult your DCS manual. For Maestro, see the section on Setting Up Maestro or consult your Maestro manual. |
| 5. | If you have performed all of the above steps and communications are still not happening, it's time to experiment. Perform these steps one at a time, then test, then the next, etc., to isolate the problem. |
| a) | Try changing which serial port is used, if possible, on the PC that's running crWebBB. |
| b) | Try changing which serial port is used on the host audio system machine. |
| c) | Try to locate a known-to-be working serial cable configured as a null modem cable and substitute it for the cable you have been using. |
