Review on Sena SD1000 Bluetooth Serial Adapter by Tom Motko

This works fairly well depending on the application. Batteries are sold separately, but they're inexpensive, around $8 each, and all you need is one. I've been using them for 6 years on ROC 809L and 827L, they work great from 9600 to 115000 kbaud. I have several 6dbi antennas, about $5 a set, and I can hit them about 100 yards, a few yards further than a football field. I need to toggle dip switches. Every time you make a program change or reboot the system, you need to change the baud rate. ABB does not allow the starting speed and starting speed to be the same. Works best with Emerson's "remotes" Some PLCs, such as B. the compactlogix 1769 series, also work.
