Rs-232 Port; Lan Port - Extron electronics DMP 128 Plus User Manual

RS-232 Port

The DMP 128 Plus has a serial port that can be connected to a host device such as a
computer running either the DataViewer or HyperTerminal utilities. The port makes serial
control of the DMP 128 Plus possible.
The DMP 128 Plus uses the following RS-232 protocols:
• 38400 baud
• 8 data bits
NOTES:
• The rear panel configuration port requires 38400 baud communication. This
speed is higher than most other Extron products. The DMP 128 Plus control
software automatically sets the connection for the appropriate speed. When using
DataViewer or similar application, make sure the host PC or control system is set
for 38400 baud.

connecting to the RS-232 port.

LAN Port

The DMP 128 Plus 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 are identical to the commands and behavior the product exhibits when
communicating by serial port or USB.
The DMP 128 Plus LAN port defaults are as follows:
IP Address
192.168.254.254
The Ethernet cable can be terminated as a straight-through cable or a crossover cable and
must be properly terminated for your application.
Crossover cable — Direct connection between the computer and the DMP 128 Plus.
•
• Straight-through (Patch) cable — Connection of the DMP 128 Plus to an Ethernet
LAN.
