not set
bootstrap loader mode disabled (default)
for firmware update via RS232
PC mode (default); the reader starts up expecting commands from
the host
stand-alone EAS mode; the reader is transmitting EAS commands
continuously after start-up; if a label with EAS bits set is detected,
the EAS Out port will change to HIGH level
serial communication interface baud rate at 57.6 kbaud (default)
serial communication interface baud rate at 115.2 kbaud

Hints for system integration
The following list should be checked if any problem (e.g.
reduced read and write distances) occurs:
Power supply cable is not correctly plugged into the
power supply
Power supply is out of specification (see Table1)
Serial interface not properly connected
Serial interface cable, power supply cable or antenna
cable are too close to the antenna
Interference received by the antenna because of an
external noise source; the remedy is the removal of the
antenna from the interfering area and execute the
command CRM_config(CFG_INIT,0). See data sheet
