Controller

The RFID System allows a selection of either the long-distance mode (automatic
selection of amplification factor) or stable-communications mode (no change in
amplification factor).
Pin 6
ON
OFF
Note Environmental noise can be easily checked with the Programming Console by
executing the NOISE CHECK command when the Controller is in long-distance
mode. Then if the value of noise reads more than 30, it is recommended that the
Controller be used in stable communications mode.
Pin 7: Not used
Do not use this pin. Always set this pin to OFF.
Pin 8: Termination Resistance
If two or more Controllers with Antennas are located closely together, the Con-
trollers must be in synchronous operation in order to prevent Antenna mutual
interference. In that case, the Controllers must be connected to one another in
series through a synchronous cable and the termination resistance of the Con-
troller at each end must be set to ON for stable communications.
Use this pin to set the termination resistance to ON or OFF.
Pin 8
ON
OFF
Note 1. Be sure to set only the termination resistance of the Controller at each end to
ON and that of any other Controller to OFF, otherwise the Controllers will not
be in stable operations.
2. Always set pins 1 and 7 of SW3 to OFF, otherwise the Controller may not
operate properly.
