2. Asynchronous Interface
2.1. Data Format and Protocol Frames
The Reader ID ISC.MR/PR/PRH101 can be configured by an asynchronous interface and data may be
written on Transponders or read from Transponders. The communication between Reader and con-
nected host (terminal, PC, etc.) is executed by means of fixed protocols. The used protocol is intended
for data bus use and is equipped with a bus address.
During data transfer via the asynchronous interface the Reader supplies the required data or a status
byte. The reply contain the transmitted control byte.
There is no reply from the Reader if there is a protocol frame failure.
