Establishing A Connection; Verbose Modes - Extron electronics DMP 128 Plus User Manual

Default IP Address
To access the DMP 128 Plus via the LAN port, the IP address, subnet mask, and the gateway address for the
devices are needed. If the addresses have not been changed, the factory-specified defaults are:
LAN 1 defaults:
IP Address
192.168.254.254
LAN 2 (V models only) defaults:
IP Address
192.168.1.254

Establishing a 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
•
Crossover cable — Direct connection between the computer and the device.
• Patch (straight) cable — Connection of the device to an Ethernet LAN.
To establish a network connection to the device:
1. Open a TCP socket to port 23 using the DMP 128 Plus IP address.
NOTE: If the local system administrators have not changed the value, the factory specified default,
192.168.254.254, is the correct value for this field.
2. The device responds with a copyright message including the date, the name of the product, firmware version,
part number, and the current date/time.
3. If the device is password protected, enter the appropriate administrator or user password.
a. If the password is accepted, the device responds with Login User or Login Administrator.
4. If the password is not accepted, the Password prompt reappears.
NOTE: The factory configured password for this device has been set to the device serial number. Passwords
are case sensitive.
Connection Timeouts
The Ethernet link times out after a designated period of time with no communication. By default, this timeout value
is 5 minutes, but the value can be changed (see
NOTE: Extron recommends leaving the default timeout at 5 minutes and periodically issuing the Query (Q)
command to keep the connection active. If there are long idle periods, disconnect the socket and reopen
the connection when another command must be sent.

Verbose Modes

Telnet connections can be used to monitor for changes that occur, such as SIS commands from other Telnet
sockets or serial port changes. For a Telnet session to receive change notices, the Telnet session must be in
verbose mode 1 or 3. In verbose mode 1 or 3, the Telnet socket reports changes in messages that resemble SIS
command responses (see
