| Reading the ADR BTR LEDs |
If you have the ADR BTRI connected right, you will be able to send and receive data. Should something be wrong, a lot of information can be derived by observing the four LEDs on the BTR.
| DS# | Color | Function |
|---|---|---|
| 1 | Green | ON when BTR has +5V power |
| 2 | Red | Blinks when BTR is sending data to PC or when BTR outputs data to CNC Forward Direction. |
| 3 | Red | Blinks when BTR outputs data to CNC - either direction. |
| 4 | Red | Blinks when BTR receives data - goes solid when file data is in BTR memory. |
Conditions to look for:
| Power ON Reset | |
|    | All LEDs flash ON, then DS2,3,4 go out |
| CNC Forward Reading | |
|    | DS2,3 pulse on when CNC reads data |
| CNC Reverse Reading | |
|    | DS2 pulses on then CNC reads reverse |
| CNC Punching | |
|    | DS2 pulses while CNC punches |
| RS422 Multi-drop protocol mode | |
|    | DS4 blinks each time the BTR is polled |
