2. Write down the 12-digit MAC (Media Access Code) address printed on the label located on the
bottom of the Serial Device Server (for example: 004017023F96). You may need this number in
order to configure the Serial Device Server.
3. If you have a wireless model, connect the antenna to the unit.
4. Connect the Serial Device Server to your serial device. If you are using RS-232, you may use
standard PC cabling (you should normally use a null modem crossover cable). The 9-pin connector
pinouts and cabling are as follows:
RS-232 connector pinouts and cabling
If you are using RS-422 or RS-485 in full-duplex or half-duplex modes, you will need a special cable.
In addition, if the Silex Serial device Server is the last one in a chain, then a 120-ohm resistor should
be placed between pins 2 and 6 (for full-duplex mode) or pins 4 and 5 (for half-duplex mode).
IMPORTANT: IF YOU ARE USING RS-422, RS-485, OR RS-485 HALF-DUPLEX, YOU MUST SET
THE SERIAL PORT LINE MODE AS DESCRIBED IN CHAPTER 3 OF THIS MANUAL.
The RS-422 and RS-485 pinouts and cabling are shown in the following diagrams:
RS-422/485 full-duplex connector pinouts and cabling
RS-485 half-duplex connector pinouts and cabling
IMPORTANT NOTE: THE SX-510 RS-422/RS-485 INTERFACE HAS NOT BEEN TESTED FOR
COMPLIANCE WITH IEC 60601-1-2:2001/EN60601-1-2 MEDICAL EMC OR ANSI/IEEE Std. C95.1-
1999, RSS-102 SAR STANDARDS. THEREFORE RS-422/485 SHOULD NOT BE ENABLED IF YOU
REQUIRE COMPLIANCE WITH ANY OF THESE STANDARDS.
