Troubleshooting
Status indicators
The green and yellow indicators built into the link connectors on each module 
provide useful feedback regarding the connection and power status:
During startup (of the local module)
•  One very short yellow flash: no valid DDC information available from 
a locally connected video monitor, no changes made to stored DDC 
information.
•  Single yellow flash: DDC information being read from a locally connected 
video monitor, but no changes made to stored DDC information.
•  Rapid yellow flash for 2 to 3 seconds, followed by single flash: New DDC 
information being read and stored from a locally connected video monitor.   
•  Two yellow flashes - Checksum error prior to copying - no information will 
be programmed.
•  Three yellow flashes - Too much data to fit into the module - the module 
can hold a maximum of two pages of DDC information.
•  Rapid yellow flashing followed by four flashes - data was lost during copying 
- the default data was substituted. Repeat the power on process.
•  Rapid yellow flashing followed by five flashes - Checksum error during 
copying - the default data was substituted. Repeat the power on process.
During operation (either module)
•  Continual yellow: Valid CATx link to other module sensed.
•  Continual green: Correct power input sensed. 
•  Green flashes: Power input too low for normal operation. In the case of the 
local module, this may be because the USB connection is unable to provide 
sufficient power. In these cases, an external power supply should be used 
with the local module.
Important
Do not attach a USB hub to the SRX remote, nor plug the SRX local module into 
another USB hub. To do so will reduce the maximum cable length over which 
the system will extend USB; also, some USB hubs may not provide enough 
power to operate the local unit.
