Rs-232 Ports; Usb Port (Front Panel); Ethernet (Lan) Port - Extron electronics DMP 64 User Manual

RS-232 Ports

The DMP 64 has two serial ports that can be connected to a host device such as a
computer running the HyperTerminal utility or DataViewer. The ports make serial control
of the switcher possible. Use the protocol information listed to make the connection.
For SIS programming details once the connection is made, see
Communications

USB Port (Front Panel)

The DMP 64 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. For SIS programming details once the connection is
made, see

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 via a 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 59).

T568A T568B
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.

assignments are swapped.
