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 4-33, a MediaLink
®
controller
connected to serial port 1 (COM1) is controlling a projector and
input devices connected to serial port 2 (COM2).
Figure 4-33 — Pass-through mode
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 SF interface. Port
redirect is enabled with an SIS command (see the “Command/
response table” earlier in this chapter).
Troubleshooting
Turn on output device(s) (plasma screens, monitors, projectors),
the IPL T SF control interface and the control devices (PC,
laptop, etc.).
