Troubleshooting
If you have experience problems with the Serial Device Server, please check the following
troubleshooting steps:
1. Make sure that you are getting power to the Serial Device Server. The orange LED should be on
solid if the proper power is being received. If it is not on, check the power supply connections,
and if possible, try a different Silex Serial Device Server power supply.
2. Make sure that you have a valid network connection.
a. Make sure that your network is operating properly (that is, other devices should be able
to communicate using the same hub, switch, or access point that the Serial Device
Server is connected to).
b. If you are using hardwired Ethernet, either the yellow LED (for 10Base-T) or the green
LED (for 100Base-T) should be lit or blinking. If they are not, make sure that the cable is
properly connected, and if possible, try a different Ethernet cable.
c. If you are using a wireless connection, both the yellow LED and green LED should be lit
or blinking. If they are not, double check your wireless settings. The SSID and security
parameters must exactly match the requirements of the access point in order for the
Serial Device Server to communicate on an infrastructure wireless network. If you are
using Ad-Hoc mode, the Serial Device Server must have exactly the same SSID, security
parameters, and RF channel as the other wireless device(s) on the network.
d. Make sure that you have a valid IP address, subnet mask and router address (check with
your network administrator to make sure that you have the correct information). You can
check to see if the IP address information is correctly set by using the ExtendView utility,
by printing a test page (press the RESET pushbutton to send a test page to a printer or
terminal connected to the serial port) or by using the PING command from a computer
system connected to the network.
3. If you have a valid network connection and IP address, but you cannot communicate with your
serial device, then:
a. Make sure that the settings of the serial port on your device exactly match the settings of
the serial port of the Serial Device Server. For example, if your device is set for 9600bps,
8-bit characters, no parity, and RTS/CTS flow control, the Serial Device Server must also
have these exact same settings.
