RICH BIT 860 will periodically update the configuration to improve performance. So far, we have updated two versions of the meter.

The wiring ports of the early configuration were all black and had 7 jacks.

The updated wiring port is green and has 5 jacks.

If you purchased the wrong version, you cannot use it. For your correct purchase, please check which version of the meter on your electric bike belongs to before buying, and then choose the appropriate purchase. grateful!
