Remote Control
This section includes:
•
Simple Instruction Set Control
•
Product Configuration Software
The DTP T EU and DTP T MK switchers can be remotely controlled via their Remote
RS-232 ports and their Configuration (USB) ports. The remote host device (such as a
computer or control system) sends Extron Simple Instruction Set commands.
Simple Instruction Set Control
The switching transmitter can be remotely controlled using SIS commands from a host
device such as a computer or control system via its Configuration (USB) port (see
item
B
on page 7) or Remote RS-232 port (see
item
E
on page 8).
The default serial port protocol of the Remote RS-232 serial port is as follows:
•
9600 baud
•
No parity
•
8-bit
•
No flow control
•
1 stop bit
Host-to-Switcher Communications
SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command character sequence. When a command is valid, the
switcher executes the command and sends a response to the host device. All responses
from the switcher to the host end 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 occurs, such as a front panel operation, loss or restoration of an input
signal, or an error condition, the switcher responds by sending a message to the host. The
switcher-initiated messages are listed below:
