Pin Name Function
2 TXAUX Transmitted data of RS232 Auxiliary Interface
3 RXAUX Received data of RS232 Auxiliary Interface
5 GND Reference GND of RS232 Auxiliary Interface
1,4,6,7,8,9 N.C. Not connected
CAUTION
Do not connect GND and SGND to different (external) ground
references. GND and SGND are internally connected through
filtering circuitry which can be permanently damaged if subjected
to voltage drops over 0.8 Vdc.
In order to meet EMC requirements:
•
connect the reader chassis to the plant earth ground by means of a flat copper
braid shorter than 100 mm;
•
connect the main interface cable shield to pin 1 of the 25-pin connector;
•
use two clip-on ferrite sleeves (type Stewart 28A2029-0A0 or equivalent) on the
main interface cable near the reader 25-pin connector.
