The settings of JP1, JP5 and JP6 must not be changed.

NAME

FUNCTION

SETTING

DESCRIPTION

JP2

bootstrap loader mode

not set

bootstrap loader mode disabled (default)

set

for firmware update via RS232

JP3

start-up mode

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

JP4

baud rate

not set

serial communication interface baud rate at 57.6 kbaud (default)

set

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

"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".
