RS-232 CONTROL

The NMP200 has an RS-232 Serial Port, which allows it to be controlled by a computer (see Front & Rear Panel Features on pg. 2). In

addition to the BiampWin software, the NMP200 offers two other methods of computer control.

Control Button Emulation: This method allows the computer to imitate the operation of an infrared transmitter or wall-mount control

panel. Although the NMP200 does not accept infrared or wall-mount remote controls itself, it can still receive ASCII characters (via RS-

232) which emulate the buttons on these types of remote controls. From the factory, remote control buttons have equivalent ASCII

characters permanently assigned to them (see table below). Therefore, actions can be assigned to remote control buttons in the same

way they are assigned to Logic Inputs. Then, using this method, the computer can output ASCII characters which are equivalent to the

commands generated by those standard remote control buttons. Control Button Emulation allows the computer to utilize up to forty button

definitions (unlike standard remote controls, which have only twenty-eight buttons). When using up

to four devices in a system, Control

Button Emulation also allows the computer to designate which device or devices should react to each control button command.

Advanced Computer Control: This method provides advanced commands, which allow the computer to retrieve or edit various NMP200

settings. The computer may also emulate control buttons. Using this method, the computer may designate up

to sixty-four devices, and

may also provide ‘real-time’ display of various settings.

This manual only describes the Control Button Emulation method of computer control. For complete details about using the NMP200 with

a computer, including Advanced Computer Control, contact Biamp Systems for manual "Computer

Control of ADVANTAGE

NMP200 ".

Each control button on an infrared transmitter or wall-mount control panel corresponds to one character in the standard ASCII character

set. The character equivalents are summarized in the following table. This table includes all forty possible buttons, their button numbers,

their ASCII code equivalents, and their factory default button definitions (no operation assigned).

The computer can initiate any functions or actions that a standard control can, by simply transmitting the equivalent control button ASCII

character. When interfacing the NMP200 to a computer, the computer must be aware that the NMP200 will ‘echo’ all characters it receives

(both from computer and Logic Inputs) via the Serial Port Transmit Data (TXD) output signal. However, from the factory, the NMP200

Logic inputs are programmed with no ‘echo character’ assigned to them.
