5.
Set the TP mode switch
(
D
) to HDBT (up) or DTP (down) as follows:
•
If the receiving device is an Extron DTP device, set the switch to
DTP
.
•
If the receiving device is HDBaseT enabled, set the switch to
HDBT
.
When the output is configured for DTP mode, remote power is available. When the output is configured for HDBT mode,
remote power is disabled and the switcher and receiver each require its own 12 VDC power supply.
ATTENTION:
•
Position this switch
before
connecting the appropriate device to the TP connector. Failure to comply can damage
the endpoint.
•
Positionnez le sélecteur
avant
de connecter l’appareil approprié au connecteur TP. Ne pas respecter cette
procédure pourrait endommager le point de connexion.
•
Do not connect these devices to a computer data or telecommunications network.
•
Ne connectez pas cet appareil à un réseau de télécommunications ou de données informatiques.
6.
Connect Over TP RS-232 and IR control.
Connect a serial RS-232 signal,
a modulated IR signal, or both into this 3.5 mm, 5-pole captive screw connector
(see
, on the previous page) for bidirectional RS-232 and IR
communication (see the image on the right to wire the RS-232 and IR connector).
7.
Connect control devices
.
Connect your computer to one of the following
DTP2 T 204 communication ports to configure and control
the switcher via SIS commands or PCS:
•
RS-232 port
— Connect the unterminated transmit,
receive, and ground wires of the RS-232 cable to the
three pins on the provided 3-pole captive screw plug,
as shown in the image at right. Connect the plug to the
rear panel Remote RS-232 connector (
other end of the cable to your computer serial port.
Protocol for the RS-232 port is
9600 baud
,
8 data
bits
,
1 stop bit
, and
no parity
.
•
Config port
— Connect a USB mini-B cable to the
front panel USB connector (see
,
, on the
next page) for USB control.
•
LAN port
— To control the DTP2 T 204 through Ethernet, connect a LAN to the RJ-45 LAN connector (see
,
). The default IP address of the scaler is 192.168.254.254, the default subnet mask is 255.255.255.0, and the default
gateway address is 0.0.0.0. (See the
in step 4 on the previous page to wire this connector.)
8.
(Optional) Connect contact closure and tally indicator devices.
The Contact/Tally
section of the rear panel (
, on the previous page) contains four captive screw
connectors, each containing two pairs of pins labeled
C
and
T
(see
1
,
3
,
5
, and
6
in the image at right). Each
C-T
pin
pair
is labeled with its contact input number (1
through 6), and each individual pin is labeled with its function:
•
C
= Contact closure input
•
T
= Tally output
•
G
= Ground (for example,
4
)
•
+V
= +V connector for the tally output power wire (for example,
2
)
To enable input switching via contact closure, connect a contact closure device to a
contact-tally port as follows:
a.
Connect a push-button contact closure device to a
C
pin of one of the contact-tally connectors.
b.
Connect the ground wire of the contact device to one of the G pins.
c.
If desired, to identify the currently selected input when the front panel LEDs are not visible, connect an indicator device,
such as an LED, to tally output pin (
T
) to the right of the connected
C
pin. When the input you are using is selected, the
corresponding tally out pin shorts to ground, which activates the connected indicator.
d.
Insert the LED+ wire of the indicator device into a +V connector.
e.
Press the button on the contact closure device to switch the connected input to the output.
