| Summary | 0000246: Investigate using RS485 instead of RS232 |
| Description | RS485 allows daisy-chaining, and the NBX modules and many of our devices can talk RS485. If we use RS485 we won't need as many NBX modules. |
| Steps To Reproduce | |
| Additional Information | One concerns is if the devices lose their RS485 addresses when power cycles. If so we'd have to reprogram them every time they get turned off or if the power cycles. The latter may not be often since we plan to have UPS power on most devices. |
