Extron electronics DMP 128 User Manual

RS-232 Port
The DMP128 has a serial port that can be connected to a host device such as a
computer running the HyperTerminal utility, or the DataViewer utility. The port makes serial
control of the switcher possible. Use the protocol information listed above to make the
connection (see Host-to-device Communications on page132).
USB Port (Front Panel)
The DMP128 has a front panel USB port that can be connected to a host device
such as a computer running the HyperTerminal utility, or the DataViewer utility. The port
makes serial control of the switcher possible. Once the connection is established, SIS
programming can begin (see Host-to-device Communications on page132)
Ethernet (LAN) Port
The rear panel LAN connector on the device can be connected to an Ethernet LAN or
WAN. Communication between the device and the controlling device is via Telnet (a
TCP socket using port 23). The Telnet port can be changed, if necessary, via SIS. This
connection makes SIS control of the device possible using a computer connected to the
same LAN or WAN. The SIS commands and behavior of the product are identical to the
commands and behavior the product exhibits when communicating by serial port or USB.
Ethernet Connection
The Ethernet cable can be terminated as a straight-through cable or a crossover cable
and must be properly terminated for your application (see figure 82).
• Crossover cable — Direct connection between the computer and the DMP128.
• Patch (straight) cable — Connection of the DMP128 to an Ethernet LAN.

Pair Wires
Pins:
A cable that is wired as TIA/EIA T568A at one
end and T568B at the other (Tx and Rx pairs
reversed) is a "crossover" cable.
A cable wired the same at both ends is called
a "straight-through" cable because no pin/pair
assignments are swapped.
