Lamps
Trigger Activity Lamps
The L2 and L4 Lamps indicate the trigger activity on the LAN cable. L2 shows the activity on the received trigger signals; L4 shows the activity on the transmitted trigger signals.
Lamp State | Indication |
---|---|
Off | The LAN cable is unplugged or the adapter is not powered. |
Green | No trigger activity. No trigger events in the past 10 milliseconds. |
Yellow | Trigger activity. One or more trigger events in the past 10 milliseconds. |
Ready Status Lamps
The L1 and L3 Lamps indicate the state of the ready signal on the LAN cable. L1 shows the state of the transmitted ready signal; L3 shows the state of the received ready signal.
Lamp State | Indication |
---|---|
Off | The adapter is not powered. |
Green |
Ready true. For L1: all the C2C-Link devices attached to this adapter and the downwards adapters (if any) are ready. For L3: all the C2C-Link devices attached to the downwards adapters (if any) are ready. |
Yellow |
Ready false. For L1: one or more C2C-Link devices attached to this adapter and the downwards adapters (if any) are not ready. For L3: one or more C2C-Link devices attached to the downwards adapters (if any) are not ready. |
Adapters Array Lamp States – Normal Situations
The above drawings show the lamps states of 3 daisy-chained adapters for 3 normal situations.
In the OK 1 situation, all adapters are ready to accept triggers but no triggers are sent by the master.
In the OK 2 situation, the master adapter sends triggers and the ready signal of all adapters is permanently high. The yellow/green toggling L2 and L4 lamps indicate the trigger activity. The steady green L1 and L3 lamps indicate that all adapters are permanently ready to receive triggers.
In the OK 3 situation, the master adapter sends triggers and the ready signal of all adapters is cycling. The yellow/green toggling L2 and L4 lamps indicate the trigger activity. The yellow/green toggling L1 and L3 lamps indicate that all adapters are not ready to receive triggers for a significant duration.
Adapters Array Lamp States – Abnormal Situations
The above drawings show the lamps states of 3 daisy-chained adapters for 3 abnormal situations.
In the NOK 1 situation, no adapters are powered. All lamps are Off.
In the NOK 2 situation, all adapters are powered but all connections are missing or incorrect.
In the NOK 3 situation, all adapters are powered and all connections are OK, but the second adapter is not ready preventing the master to send new triggers. This situation is considered as abnormal when it persists.
Troubleshooting Guide
Lamps state | Indication and possible causes | Action |
---|---|---|
All lamps Off | The adapter is not powered. | Apply power to the adapter |
L2 Off L1 Green |
The external connection to the IN connector is missing or incorrect. |
For the master adapter, this is OK: nothing to do! For the other adapters: check and correct the connection to the OUT connector of the previous adapter in the daisy-chain. |
L4 Off L3 Green |
The external connection to the OUT connector is missing or incorrect. |
For the last slave adapter of the daisy-chain, this is OK: nothing to do! For the other adapters: check and correct the connection to the IN connector of the next adapter in the daisy-chain. |
