Maximum Devices Per Port
CoreStation has 5 RS-485 ports and in total CoreStation supports maximum of 64 slave devices but each port supports up to 31 slave devices with daisy chain.
- Connecting 50 devices to RS-485 port 0 with daisy chain = one port only supports up to 31 slave devices
- Connecting 31 devices to RS-485 port 0 with daisy chain
- Connecting 15 devices to RS-485 port 1 with daisy chain
- Connecting 18 devices to RS-485 port 2 with daisy chain
= 64 slave devices are supported
Maximum Biometric Devices
Although the maximum of 31 slave devices is supported with other master devices, we normally recommend having less than 8 biometric devices as slave device for performance reasons.
However CoreStation has a impressive processing power of 400,000 genuine matching / 1 sec and 80,000 imposter matching / 1sec.
You can make calculations of performance based on this statistic based on the number of users you have at your site to consider if having multiple biometric devices as slave devices would be acceptable.
1:n matching where the user's fingerprint template is in the device
1:n matching where the user's fingerprint template is not in the device
