Direct Port Access (Ports 2001 Through 2002)
Direct access allows a direct, one-to-one connection to any of the serial ports using a
reserved IP port number:
COM1: direct access port #2001
COM2: direct access port #2002
When a TCP session is initiated to port 2001 through port 2002, all data sent and received
passes directly to and from that port without any processing. Serial port parameters
should be set via Telnet connection prior to using direct access.
Using direct access
1. Access the unit via Telnet and configure the COM port parameters as desired using SIS
commands (see the
Command/response table ).
2. Close the initial Telnet session.
3. Open a direct access Telnet session to the selected port by entering the IP address
followed by a space then the port number (for example, 192.168.244.244 2001).
4. Send serial commands directly through the selected COM port to the attached A/V
device.
5. Close the Telnet session to end the direct access session.
NOTE: You can force the direct access session closed by logging on as
Administrator and entering ”Esc
X!
* 0CD } ”, where
X! is the selected
COM port.
Port redirect
Using port redirect, either serial port can be configured as a pass-through connection,
allowing data to be sent and received directly to and from the serial port back to the client
(PC) without any processing. In figure 55, a MediaLink
® controller connected to serial
port 1 (COM1) is controlling a projector and input devices connected to serial
port 2 (COM2). Port redirect is enabled with an SIS command (see the
Command/
response table ).
