RFC 2217 Remote Modem Control Support RFC 2217 allows you to access your device’s modem control signals over the network. It is especially useful for migrating applications that use modem controls from a direct serial connection to a serial device server network connection. You can utilize RFC 2217 from the Silex Serial Port Emulator software (see below), or by connecting to TCP port 9200 (for Serial Port 1) or port 9201 (for Serial Port 2) from your application program.
PAGE 41
Print Server Mode You can use the SX-560 as a standard TCP/IP print server, which is very useful if you are connecting the SX-560 to a serial printer. The SX-560 supports the following standards:  lpr/lpd. This is one of the most popular ways to print on a TCP/IP network. Check your computer’s documentation to determine how to set up an lpr print queue. Usually this simply involves specifying the IP address of the SX-560 as the printer’s address or host name.
PAGE 42
and data mode by sending the appropriate commands. This capability is similar to the console mode switching described in the previous section, but has the following advantages;   Your device can initiate a network connection Operation is compatible with software that uses the AT command set The drawback, however, is that there is a slight delay when switching from data mode to AT command mode.
PAGE 43
Chapter 5 Interfacing the SX-560 to the OEM Device In order to connect the SX-560 module to your device, you will need to provide either a custom daughtercard or a special cable. Both of these solutions will require a 40-pin female connector on one side, with the appropriate connector(s) for connecting to your device’s circuitry on the other side. The custom daughtercard is generally a superior solution because it provides better mechanical connections for greater overall system reliability.

Appendix A Advanced Security Configuration There are numerous possible security settings. It is therefore important that you verify the appropriate settings with your network administrator. If you enter the settings incorrectly, the SX-560 will not be able to communicate on your network. The following table summarizes the wireless settings required for each encryption mode and authentication type: Authentication Type En cry pti on Mo de Disable 64-Bit WEP 128-Bit WEP WPA WPA2 WPA2WPA Dynamic WEP 802.
PAGE 77
    Dynamic WEP. Dynamic WEP uses WEP encryption with an 802.1X EAP authentication method. It is not necessary to set keys with this method, because they are automatically assigned. WPA2. WPA2 is the latest and strongest wireless security standard. It uses CCMP encryption. Like WPA, it can be used either with a pre-shared key or with 802.1X authentication. Wi-Fi Protected Access (WPA). WPA uses TKIP encryption, and can be used with either a preshared key (PSK) or with 802.1X authentication. WPA2-WPA.
