VP-440X – Connecting VP-440X
Connecting to VP-440X via RS-232
You can connect to the VP-440X via an RS-232 connection using, for example, a PC.
VP-440X features two RS-232 3-pin terminal block connectors:
• CONTROL – to control VP-440X (for example, via a connected PC) or for VP-440X
to control an external device (for example, the projector on the HDMI output).
• DATA – RS-232 on this port is passed via HDBT to/from the RS-232 port on the
HDBT receiver.
For VP-440X to control an external device at the HDBT receiver (for example, the projector
on the HDBT receiver’s output), connect the CONTROL port to the DATA port (Rx to Tx and
Tx to Rx) and connect the external device to the HDBT receiver’s RS-232 port.
Connect the RS-232 terminal block on the rear panel of the VP-440X to a PC/controller, as
follows:
From the RS-232 9-pin D-sub serial port connect:
• Pin 2 to the TX pin on the VP-440X RS-232 terminal
block.
• Pin 3 to the RX pin on the VP-440X RS-232 terminal
block.
• Pin 5 to the G pin on the VP-440X RS-232 terminal
block.
Wiring RJ-45 Connectors
This section defines the TP pinout, using a straight pin-to-pin cable with RJ-45 connectors.
It is recommended that the cable ground shielding be connected/soldered to the connector
shield.
