Serial Data Transfer and IR Flow Control

The illustration in FIG. 19 shows the bidirectional serial data transfer and IR flow control when DXLink Fiber units are
used in Endpoint Mode with an Enova Digital Media Switcher. The switcher has an integrated NetLinx Central Control
Processor which provides native AMX control at each remote location fed by a DXLink Fiber Transmitter / Receiver.
Control is sent over fiber optic cable (via the fiber optic transceivers).

Wiring for Serial Data Transfer
The RS-232 (serial) ports are the 3-position screw terminal blocks on the rear of the units to the right of the
ICS LAN 10/100 connector. The RS-232 ports can be bound and controlled via the integrated NetLinx Central
Controller in the Enova DGX or via another network connected NetLinx Central Controller. For an illustration of serial
data transfer, see FIG. 19.
Note: On both DXLink Fiber units, the RS-232 connector pinout is "TX - RX - Ground."
To wire the RS-232 (serial) connectors on the RX/TX for data transfer:
1.
Wire the RS-232 connectors on the units according to the pinout directly above the connector.

2.
Use the command RXON to enable this port on the Transmitter and the Receiver. (For complete Serial
SEND_COMMAND programming information, see page 80.)
