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.

You can force the direct access session closed by logging

on as administrator and entering “Esc X1 * 0CD	”,
where X1 is the selected COM port.

Port redirect

Using the port redirector, 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 4-34, a MediaLink controller connected to serial port 1 (COM1) is controlling a projector and input devices connected to serial port 2 (COM2).

Troubleshooting

Turn on output device(s) (plasma screens, monitors, projectors), the IPL T control interface and the control devices (PC, laptop, etc.).

If the output A/V device cannot be remotely controlled, check the following:

Power connections

1.	Ensure that all devices are plugged in.
2.	Make sure that each device is receiving power. The
	interface’s front panel power LEDs light if the device is
	receiving power.
Data connections
1.	Check the cabling connections and make adjustments as
	needed. The Link LEDs on the IPL T control interface and
	the computer should be solid green if a network
	connection is detected. If these LEDs are not lit, either the

cable is faulty or not plugged in, or the wrong type of

Port redirect can also be used in conjunction with Extron’s Serial Link Software (refer to the Serial Link Software User’s Guide) to set up virtual COM ports on a PC or laptop, to monitor COM port data and pass it to the LAN, or to set up a projector or other RS-232 controlled A/V devices via the IPL T interface. Port redirect is enabled with an SIS command (see the Command/ response table earlier in this chapter).

2.Try to ‘ping’ the unit by typing ‘ping 192.168.254.254’ at the DOS command prompt, or use the Web address provided to you by your system administrator. If you get no response:

a.Make sure your unit is using the appropriate Subnet mask (check with your system administrator).

b.Make sure your PC does not have a software firewall program which might block the IP address of the unit.

3.If contact is established with the unit, but the unit’s Web pages cannot be accessed by your Web browser, verify (in the Options or Preferences menu) that your Web browser is configured for direct network connection and not set up to use a proxy server.

If you are still experiencing problems, call the Extron S3 Sales & Technical Support Hotline if needed.
