Extron DTP T UWP 4K D Series • Remote Control 13
Remote Control
This section includes:
• Contact Closure Control
• Simple Instruction Set Control
The DTP T UWP 4K D series of transmitters can be remotely controlled via their front panel
configuration (USB) port, rear panel Remote RS-232 port, and rear panel Remote Contact
port.
Contact Closure Control
The rear panel Remote port provides a way to select an input to the extender using a
remote contact closure device. For contact closure pin assignments, see “Contact” in item
C
, page 7.
To select a different input number using a contact closure device, momentarily short the pin
for the desired input number to ground. To force one of the inputs to be always selected,
leave the short to ground in place.
Simple Instruction Set Control
The DTP T UWP 4K D series of extenders can be remotely controlled using SIS commands
from a host device such as a computer or control system via its rear panel Remote RS-232
port (see item
C
on page 7) or front panel Configuration (USB) port (see item
D
on
page 6).
The default serial port protocol of the RS-232 port is as follows:
• 9600 baud • No parity • 8 data bits
• No flow control • 1 stop bit
Host-to-Extender 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
extender executes the command and sends a response to the host device. All responses
from the extender 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.
Extender-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 extender responds by sending a message to the host.
Examples of the extender-initiated messages are listed below:
