Pairing AC900 with R2c
Effective immediately, AC900 devices can now be paired with R2c readers. However, this is only possible for AC900 devices with a core board that is version FEM565. When purchasing a brand new AC900 terminal, remember to notify the sales person that the terminal is to be paired with R2c as the slave reader.
If you are already using a AC900 device at your place, please check the core board's version (either FEM500 or FEM565) before pairing it with an R2c reader. You can check this info by using the FingerTec Device Info tool (Click HERE to download).
To Enable AC900 to pair with R2c, Press Menu > Option > Access Option > 485 Reader Fun. > Y or N > Set to Y > Save > Restart both the AC900 and R2c.
For your reference, below is an installation diagram for the AC900 and R2c devices with the new AdapTec Plus.
