Complete lack | a) Three to five seconds after being powered up, | |
of operation | if no LEDs (on front and rear panel) indicate | |
after | activity, verify that the AC power cord is | |
installation | ||
connected, and the AC power source is | ||
| ||
| energized. | |
| b) If some of the LEDs are active, refer to the | |
| LED INDICATORS Section below for | |
| additional information. | |
| c) The Interface Unit has been inadvertently set | |
| to Group ID 900 for more than 5 seconds. | |
| Set the Group ID to the correct setting and | |
| power off/on the Interface Unit to return it to | |
| its normal operating mode. | |
No PTZ or | a) If the Channel LED does not indicate Bilinx | |
menu access | communication, verify that the camera is | |

| INFORMATION Section. The Video Input | |
| Channel LEDs can indicate whether the | |
| LTC 8016 is using Bilinx communication. Refer | |
| to the LED INDICATORS Section below for | |
| additional information. | |
| b) Verify that the Interface Unit is connected to | |
| the correct block of system video inputs | |
| based on the Group ID switch settings. | |
| c) The camera is located at a distance that | |
| exceeds Bilinx communication limits. Refer | |
| to the CAMERA VIDEO CONNECTIONS | |
| Section for maximum distance details. | |
| d) Up to 20 seconds may be required when a | |
| ||
| the Interface Unit before control is possible. | |
| No response before this time has elapsed | |
| should be considered normal. | |
