[RS-485 network only]: RS-485 supports distances up to 4,000 feet (1,200
meters) and/or 31 readers. To extend these limitations, contact Bioscrypt
Technical Support. Typically no end-of-line termination is required unless
the total run exceeds 2,000 feet.

[RS-485 network only]: Set up network using 9600 baud rate. Only
increase this data rate after the system is operating properly at 9600.
