User Guide Manual

To establish a network connection to the DMP64:

1. Open a TCP socket to port 23 using the mixer 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 DMP64 responds with a copyright message including the date, the name of the

product, firmware version, part number, and the current date and time.

a. If the DMP64 is not password-protected, the device is ready to accept SIS

commands immediately after it sends the copyright message.

b. If the DMP64 is password-protected, a password prompt appears below the

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.

b. If the password is not accepted, the Password prompt reappears. Repeat step 3.

Connection Timeouts

The Ethernet link times out after a designated period of time of no communications. By

default, this timeout value is set to 5 minutes but the value can be changed. See the

Configure Port Timeout commands in the “Command and Response Table for

Basic SIS Commands” beginning on page98.

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 Mode

Telnet connections can be used to monitor for changes that occur, such as SIS

commands from other Telnet sockets or a serial port. 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.
