Communication
Synchronization
The interface receives and transmits serial asynchronous data at voltage levels compatible with the RS232
specification.
Signal
Logic 1 = -3 volts to –15 volts
Logic 0 = +3 volts to +15 volts
Baud Rate
9600 default (optional: 1200/2400/4800/19200)
Transmission Protocol
The user may select from three different protocols: Protocol 0, 1, and 2.
Upon reset, the reader sends the power-on response “:”, depending upon the configuration setting. The reader then
configures itself to the protocol of the first command from the host. From this point on, the protocol is
unchangeable until a reset occurs.
