IN1806 and IN1808 Series Scaling Presentation Switchers • Operation 49
Changing the starting point
By default the UART start point is 2000. You can change the starting port number by any of
the following methods:
• Using the Product Configuration Software (see IN1806 and IN1808 Series PCS Help file)
• Using SIS commands (see the Set UART start point SIS command on page 80)
RS-232 protocol
You also may need to set the RS-232 protocol of the addressed port to match the connected
device. You can do this using any of the following methods:
• Using PCS (see the IN1806 and IN1808 Series PCS Help file).
• Using SIS commands (see the Serial Port Configuration SIS commands on
page 80).
Captive Screw IR Signal Insertion
Figure 31 shows an example of a typical captive screw Ethernet insertion, in which an
Extron control system provides IR control of a display via the scaler. Configure this type of
insertion as follows:
