Instruction Manual – Enova DGX 8/16/32 Digital Media Switchers
Serial Connection via Control (DB-9) Port
RS-232 Pin Diagram
A serial connection via the Control port requires a null modem cable that matches the pin diagram in
FIG. 31 for RS-232 without hardware flow control. Enova DGX Switchers require pins 2, 3, and 5 only.
Serial Port Settings
To establish external serial control via the Control (DB-9 serial) port:
1.
Plug one end of the null modem serial cable into the Control port on the enclosure.
2. Plug the other end of the serial cable into the serial port on the serial controller.
3. If not already on, apply power first to the Enova DGX Switcher and then to the source and
destination devices (see “Applying Power and Startup” on page 35).
Caution: To avoid system damage, follow the power-up sequence on page 36. We recommend
attaching all power cords to a surge protector and/or AC line conditioner.
4. Setup and run the desired method of control:
AMX Controller – For control programming information, see the instruction manual for the
specific interface.
Terminal emulation* – Open the program, set the
COM port settings to match the default ones in the
“Enova DGX Serial Port Settings” table to the right.
5. Execute a test switch to make sure the system is working
properly (see page 49).
* For terminal emulation via the serial port, use the Terminal view in DGX Configuration Software
(see page 173) or another terminal emulation program.
