- Component: Serial Communication
- Control System: Venus 1500 v3 or v4
Cause
- The controllers multiplier is set to 128 but should be set to 1.
Resolution
- Note: Issue can cause full communication failure but power cycle will correct. If the sign looses communication, shut the display power off for 20 seconds and then back on to bring communication back.
Step 2: Set the multiplier on the controller to 1 using M2Config utility software.
- Under the Configuration tab, click the Communications folder.
- Change the Multiplier from "128" to "1".
- Click File -> Set Configuration (blue down arrow). -> Sign should reset.
- Repeat steps 1 & 2 to verify that the change has occurred after the sign has finished booting. If the multiplier is still at 128 Call Daktronics technical support.
- Tech support will need remote access to a computer controlling the display to help remedy this issue.
