Rs-232 And Rs-422 Remote Connections - Extron electronics DXP DVI Pro User Manual

The cable used depends on your network speed. The switcher supports both
10 Mbps (10Base-T — Ethernet) and 100 Mbps (100Base-T — Fast Ethernet), half-duplex
and full-duplex, Ethernet connections.
• 10Base-T Ethernet requires CAT 3 UTP or STP cable at minimum.
• 100Base-T Fast Ethernet requires CAT 5e UTP or STP cable at minimum.
The Ethernet cable must be properly terminated for your application as either a crossover or
a straight-through cable.
• Crossover cable — Direct connection between the computer and the DXP switcher
Patch (straight-through) cable — Connection of the DXP to a network via a router,
•
hub, or switch
NOTES:
• Do not use standard telephone cables. Telephone cables do not support Ethernet
or Fast Ethernet.
• Do not stretch or bend the cables; this can cause transmission errors.

RS-232 and RS-422 Remote Connections

The DXP switchers have two serial ports through which the DXPs can be configured via SIS
commands (serial commands that control the switcher through this connector).

and use the control software.
NOTES:
• The switcher can support either the RS-232 or RS-422 serial communication
protocol, and operate at 9600, 19200, 38400, or 115200 baud rate.
• See
on page 44 to configure this port using the front panel buttons.
If desired, you can connect an MKP 2000 or MKP 3000 remote control panel to this port.
See the user guide of either product for details.
