2-Series Integrated Dual Bus Control System Troubleshooting

TROUBLE

Unexpected response from control system.

PWR LED does not illuminate.

ERR LED illuminates.

POSSIBLE

CAUSE(S)

Network devices are not communicating to the control system.

CORRECTIVE ACTION

From the Viewport, poll the network (F4) to verify communication.

Control system is not receiving power.

Hardware or software failure, hardware incompatibility with software definitions, or programming error.

Poor analog versus serial signal definition in the

SIMPL Windows program.

Verify that supplied power cord is properly attached to control system and the other end is securely plugged into an outlet.

Verify that hardware configuration matches software configuration (i.e., card is in proper slot as defined by program). If using PRO2, depress MSG button on front panel for specific error. Use Viewport to display the error log.

Confirm proper signal definition in the program. Compilation error

RLCMCVT166 &

RLCMCVT177.

System locks up.

Various.

A/V system device does not respond.

IRP2 or serial port not placed properly.

Hold down SW-R button on control system front panel to bypass program and communicate directly with processor. Refer to

"Troubleshooting Communications" for more details. Refer also to the "Troubleshooting Non-

Functioning Units" procedures following this table.

Verify placement of IRP2 (hold phosphor card under IRP2 while pressing button) and tighten serial cables.

Used wrong IR/serial port. Verify that proper IR or serial port is defined.

Serial cable miswired.

Verify that serial cable is wired correctly for RS-

232, 422, 485.

Troubleshooting Non-Functioning Units

Perform the following procedures to correct system lock-up problems that are not

resolved via the procedures in “Troubleshooting Communications” on page 21.

1. Connect a DB9 straight-through RS232 cable between the AV/PRO2 and a

PC. Refer to “Establishing Communication with the AV2/PRO2” on page

19 for more information.

2. Open Viewport and select Setup | Communication Settings to open the

“Port Settings” window.

3. In the window, select RS-232 (Connection Type), 57600 (Baud Rate), N

(Parity), 8 (Data Bits) and 1 (Stop Bits) and click OK.

4. Power down the AV2/PRO2.

5. While powering up the AV2/PRO2, press and hold ALT and K on the keyboard until the following text (or similar) appears in Viewport:

System Monitor [v1.001 (0001)]

12-19-01 16:25:23 32 MB RAM, 4MB FLASH

CS>

NOTE: After this, you can increase the baud rate to 115200 (for faster communication) by pressing F8 on the keyboard and then selecting 115200 from the

“Set Baud Rate” window.
