Extron electronics DTP CrossPoint 4K Series - Host-To-Switcher Instructions; Switcher-Initiated Messages

DTP CrossPoint 4K Series Matrix Switchers • Programming Guide 66
Host-to-Switcher Instructions
The switcher accepts SIS (Simple Instruction Set) commands through the rear panel
Remote RS-232 port, the front panel Configuration port, and the rear panel Ethernet
(LAN) port. 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.
Each switcher 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.
Switcher-Initiated Messages
When a local event such as a front panel operation occurs, the switcher responds
by sending a message to the host. The switcher-initiated messages are listed below
(underlined).
The switcher does not expect a response from the host, but, for example, the host program
might request a new status.

{day, date, time}
]
The switcher initiates the Copyright message on the Remote RS-232 port when it is first
powered up and on a newly connected Internet protocol (IP) port. DTPCPxx is the model
name, Vx.xx is the firmware version number, and 60-nnnn-nn is the switcher part number.
Password:
]
The switcher initiates the Password message immediately after the copyright message
when the controlling system is connected using TCP/IP or Telnet and the switcher is
password protected. This message means that the switcher requires an administrator or
user level password before it will perform the commands entered via this link. The switcher
repeats the password message response for every entry other than a valid password until a
valid password is entered.

The switcher initiates the Login message when a correct administrator or user password
has been entered. If the user and administrator passwords are the same, the switcher
defaults to administrator privileges.

The switcher initiates the Qik message when a front panel tie creation has occurred.
Rprnn

The switcher initiates the Rpr message when a memory preset has been recalled from the
front panel. “nn” is the preset number.
GrpmDn*y

The switcher initiates the Grpm message when a front panel Volume knob is adjusted. “n” is
the control: 1 (Volume) or 2 (Mic Volume). “y” is the variable.
Exen

The switcher initiates the Exe message when the front panel security lockout (executive
mode) is toggled on or off from the front panel. “n” is the executive mode: 0, 1, or 2. See
Setting the Front Panel Locks (Executive Modes) on page 48 for more information on
the Lock modes.
