Instruction Manual – HDMI-UTPRO-0808
Control Port (DB-9)
The Control (DB-9 port) on the HDMI UTPro is reserved for firmware upgrades to the CPU. If needed, this port can also
attach to a PC for using EDID Programmer or XNConnect software or for other traditional serial port functions
(e.g., BCS commands or third-party control*).
The Control port can be used for matrix switching control functionality as an alternative to Native NetLinx control
(which is accessed through the LAN 10/100 port and includes additional NetLinx functionality). We recommend using
only one at a time, with native NetLinx as the preferred method and the RS-232 port as a backup because commands on
the Native NetLinx connection will be accepted on a first come/first served basis (which may conflict with the BCS
commands).
* If using a third-party controller, see the controller documentation for operating instructions.
Note:
Attaching an external serial controller is an optional installation procedure.
Attaching Control Port to an External Serial Controller (Optional)
An external serial controller is any device that can send and receive ASCII code over an RS-232 (null modem) serial
cable attached to the Control port on the rear of the enclosure. PCs are common serial controllers. PC requirements for
BCS (Basic Control Structure) commands are provided below; for the EDID Programmer, see page 103; and for
XNConnect, see page 111.
PC Requirements for BCS
Windows XP
Professional

Terminal emulation program (e.g., TeraTerm, PuTTY, or HyperTerminal)
Serial port
To establish external serial control over a null modem serial cable:
1.
Use a null modem cable that matches the pin diagram in FIG. 28 for RS-232 without hardware flow control. The
AMX equipment requires pins 2, 3, and 5 only.
