Installing the Serial Device Server
Silex

Part Number 140-00188-180
5. Plug the Serial Device Server power supply adapter into a suitable AC receptacle, and then plug the
power supply cable into the Serial Device Server. Alternatively, you can use pin 9 on the 9-pin
connector to provide power to the Serial Device Server (1 amp @ +5V is required). The Serial Device
Server will run through a sequence of power-up diagnostics for a few seconds.
 If the Serial Device Server is operating properly, the LEDs will blink momentarily and then go out,
the yellow and green LEDs will illuminate if the wireless network is active, and the orange LED
will illuminate, indicating the device is receiving power.
 The unit powers up in the Normal mode, which provides for connection from the network to
device(s) connected to the serial port of the Serial Device Server.
 If the orange LED blinks continuously in a regular pattern, a problem exists. If this is the case, try
powering the unit OFF and then ON again.
.
6. Connect the Serial Device Server to your network through a switch or hub using a category 5 (CAT5)
Ethernet cable. Serial Device Server wireless models automatically detect the presence of this cable,
and will switch off the wireless networking functionality as long as the cable is plugged in.
7. The Serial Device Server’s IP address must be configured before a network connection is available.
If your network offers DHCP (Dynamic Host Configuration Protocol), the Serial Device Server will
automatically search for a DCHP server upon power up and obtain an IP address. If your network
does not offer DHCP, a static (fixed) IP address must be assigned (see your system administrator for
assistance). If you use DHCP, make sure that the length of the DHCP lease is adequate so that the
IP address of the Serial Device Server does not change.
Monitoring Serial Device Server Status
You can monitor the Serial Device Server status using the yellow, green and orange LED status
indicators on the monitor. Table 2 defines the default functions of the LED status indicators.

NOTE: Pin 9 is normally configured for supplying +5V from an external power source in lieu of using the AC power
supply adapter. If you wish to use this pin as the Ring Indicator (RI) modem signal on the SX-500 (not available on the
SX-510), open the enclosure and move the jumper on connector JP1 onto pins 2 and 3 of this connector.
NOTE: SILEX RECOMMENDS USING A HARDWIRED ETHERNET CONNECTION FOR CONFIGURING WIRELESS SERIAL
DEVICE SERVERS. If you have a wireless Serial Device Server model and cannot use an Ethernet connection, refer to
step 4 in the First Time IP Address Configuration section of this chapter for instructions on how to set up the Serial
Device Server using a completely wireless Ad Hoc environment.
