NAME
FUNCTION
JP2
bootstrap loader mode
JP3
start-up mode
JP4
baud rate
SETTING
DESCRIPTION
not set bootstrap loader mode disabled (default)
set
for firmware update via RS232
not set
PC mode (default); the reader starts up expecting commands from
the host
set
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
not set serial communication interface baud rate at 57.6 kbaud (default)
set
serial communication interface baud rate at 115.2 kbaud
The settings of JP1, JP5 and JP6 must not be changed.
11.2 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
"SLRM900; I-CODE Long Range Reader Module,
protocol Reader-Host"
• Antenna is mounted in metal environment; the remedy is
to place a non-metal space keeper between the antenna
and the metal
• Antenna is not designed according to application note
"I-CODE, Design of Read/Write antennas".
