Using the SX-560
Part Number 140-00192-100
where ipaddress is the IP address of the SX-560 and portnumber is the SX-560 TCP port number. For
example:
telnet 192.168.5.53 9100
In this example, if you have a serial printer or other device capable of displaying ASCII characters
connected to the SX-560 Serial Port 1, then every character you type should be printed on that serial
device (buffered serial devices may need you to type a control character such as a formfeed (CONTROL-
L) before the characters are printed).
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.
ECable Mode
Normally, it is up the computer to initiate a connection to the SX-560. For some applications, it is
desirable for the SX-560 to initiate the connection to the computer. The SX-560 supports this capability
through its ECable feature.
To set E-Cable mode, use a web browser to access the SX-560 internal web pages (see chapter 3 for
instructions on using the internal web pages). After you have logged in, click I/O port on the left side of
the screen.
You can now enable ECable mode and set the required parameters.
1. Select the desired port (S1 for Serial Port 1 or S2 for Serial Port 2)
2. Enable ECable mode by clicking the radio button.
3. Enter the address (Destination Address) of the computer or other device that will be
communicating with the SX-500)
4. Enter the TCP port number (Destination Port) used by the destination device for communicating
with the SX-560 (must be greater 1023).
5. If desired, change the ECable Connection Attempt Time. This specifies the time interval between
connection attempts. For example, by default the SX-560 will try once every 30 seconds to make
a connection to the destination device; if it fails to make this connection, it will wait 30 seconds
before attempting again. Changing this interval will reduce or increase the amount of network
traffic.
