(RP Series System) Poor Infrared Reception of the Remote Control

Publication Date:  2015-08-11 Views:  256 Downloads:  0
Issue Description
The remote control of an RP series system is not responsive.
Handling Process
Step 1 Make sure the infrared transmission area is facing the telepresence system.

Stay within 6 meters of the RP series system, and point the infrared transmission area (shown in Figure 6-7) of the remote control to the infrared receiver (shown in Figure 6-8) in the RP series system. Test some keys on the remote to see if it is responsive.

If the remote control is still not responsive, go to step 2.

Step 2 Turn off the tubes in the conference room. Use the method described in step 1 to operate the remote control.

 If the remote control becomes responsive, the tubes are interfering with the infrared reception. In this case, replace the tubes.

 If the remote control is still not responsive, go to step 3.

Step 3 Verify that the infrared cables are connected according to Figure 6-9.

Ensure that the RJ45 port is connected to the COM1 port on the RP series system.

If the remote control is still not responsive, go to step 4.

Step 4 Remove the infrared cables from the RP series system, as shown in Figure 6-10. Use the method described in step 1 to operate the remote control within 6 meters of the RP series system.

 If the remote control becomes responsive, the infrared receiver delivered with the RP series system may be incorrectly installed. If this is the case, install the infrared receiver according to Figure 6-11.

 If the remote control is still not responsive, go to step 5.

Step 5 Take photos of the conference room. Send them to the R&D department in Huawei HQ.

NOTE:
Sources of interference include ambient lights and plasma displays.
Root Cause
Possible Cause:

 The infrared transmission area of the remote is not pointing at the telepresence system.

 Ambient lights are interfering with the remote control signals.

 The plasma display is interfering with the remote control signals.

 Infrared cables are not correctly connected.

 Infrared cables are faulty.
