Extron electronics DMP 128 FlexPlus User Manual

DMP 128 FlexPlus • Remote Control and Configuration 125
Establishing a Network Connection via LAN
1. Open a TCP socket to port 23 using the DMP 128 FlexPlus 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 128 FlexPlus 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
.
b. If the password is not accepted, the Password prompt reappears.
NOTES:
• The Ethernet link times out after a designated period of time of no communications.
By default, the timeout value is set to 5 minutes and can be changed (see Set
global IP port timeout on page129).
• 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.
USB Config Port
The DMP 128 FlexPlus has a front panel USB port that can be connected to a computer
as a host device running either the HyperTerminal or DataViewer utilities for control of the
device. Once a connection is established, SIS programming can begin (see Host-to-
Device Communications on the next page).
Verbose Modes
Telnet connections are used to monitor changes that occur, such as 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 (Set verbose mode on page132). In verbose
mode 1 or 3, the Telnet socket reports changes in messages that resemble SIS command
responses.
Tagged and Untagged Responses
When a query command is sent in verbose mode 0 or 1, only the “untagged” value is
returned. When a query command is sent in other verbose modes, the response is “tagged”
and resembles the response to a set command.
Examle: The gain query command EG40000AU} is sent. The following responses
appear depending on the verbose mode:
• Untagged (verbose 0 or 1):
626], just the gain value with no other information.
• Tagged (verbose 2 or 3):
DsG40000*626], the type of query sent, the OID queried,
and the gain value.
NOTE: All query responses listed in this guide are untagged.
