Silex technology SX-500-1402 manual RS-232 connector pinouts and cabling

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:

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).

When power is applied all three LEDs will be lit. 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 green and yellow LEDs will turn off and then will show the device status as shown in Table 2 in the next section. The orange LED should remain solidly illuminated.

∙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.

NOTE: Pin 9 is normally configured for supplying +5V from an external power source in lieu of using the AC power supply adapter.

6.Connect the Serial Device Server to your network through a switch or hub using a category 5 (CAT5) Ethernet cable. Then cycle power on the device to switch the server into wired mode and switch off the wireless networking functionality as long as the cable is plugged in.

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. Device Keys (unit private key and WPA2-PSK) must be entered via an isolated wired connection
