Extron electronic DVS 510 SA Using SIS Commands

DVS 510 Series • Remote Configuration and Control 48

To access the DVS 510 or DVS 510 SA via the Ethernet port, obtain the IP address of the

scaler from your network administrator. If the IP address has been changed to an address

comprised of words and characters, you can determine the actual numeric IP address using

the ping (ICMP) utility (see “IP Addressing” on page 116 for more details). If the IP address

has not been changed, the factory-specified default is 192.168.254.254.

Establish a network connection to a DVS as follows:

1. Open a TCP connection to port 23, using the IP address of the scaler.

The scaler responds with a copyright message that includes the date, the name of

the product, firmware version, part number, and the current date and time (see

“Scaler-initiated Messages” on the next page).

NOTE: If the scaler is not password-protected, the device is ready to accept SIS

commands immediately after it sends the copyright message.

If the scaler is password-protected, a password prompt appears below the

2. If the scaler is password protected, enter the appropriate administrator or user

password.

3. If the password is accepted, the scaler responds with Login User or Login

Administrator.

4. If the password is not accepted, the Password prompt reappears.

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

this timeout value is set to 5 minutes, but the value can be changed (see the Set current

connection port timeout command on page 71, in the Command and Response Table for

IP-specific SIS Commands).

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, Extron recommends disconnecting and reopening the connection

when another command must be sent.

Using SIS Commands

SIS commands consist of one or more characters per command field. They do not require

any special characters to begin or end the command character sequence. When the DVS

determines that a command is valid, it executes the command and sends a response to the

host device. Each scaler response to an SIS command ends with a carriage return and a line

feed (CR/LF = ]), which signals the end of the response character string. A string is one or

more characters.
