Pin Name Function
2 TXAUX Transmitted data of auxiliary RS232
3 RXAUX Received data of auxiliary RS232
5 GND Reference GND of auxiliary RS232
1,4,6,7,8,9 N.C. Not connected
CAUTION
Avoid simultaneous connection to 25-pin and 9-pin signals of the auxiliary
RS232 interface.
CAUTION
When connected to a C-BOX 3x0/4x0, Matrix-1000™ can only
communicate through its Auxiliary Interface. The Matrix-1000™ 9-pin
Auxiliary port connector cannot be used for communication (i.e.
configuration through VisiSet™). To configure Matrix-1000™ through the
9-pin connector inside the C-BOX 3x0/4x0, the C-BOX 3x0/4x0 must first
be configured. See the relative C-BOX Installation Manual for details.
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;
