The RCU includes programming software for assignment of specific functions to the external controls. [. . . ] The icon and device number indicate which device the pot is programmed to control. When the mouse pointer is positioned over the fader, a pop-up `hint' appears which provides a detailed description of the function which the pot is programmed to perform. Connecting Pots to the RCU: The RCU is designed to be used with linear taper pots. The resistance value of the pots can be as low as 5K ohms or as high as 50K ohms. Pins 1 through 23 of the "Remote Control" connector on the RCU are for pot inputs. Pin 24 is a reference voltage output (which is approximately +5 volts DC), and pin 25 is ground. The `high' (clockwise) side of all pots should be connected to the reference voltage output on pin 24 of the remote control connector. The `low' (counter-clockwise) side of all pots should be connected to ground on pin 25 of the remote control connector. The wiper of each pot should be connected to the pin corresponding to the pot number (1 through 23). In some cases, the wiper could be connected to more than one pin if you want to control more than one volume level with the same pot (to simulate a `ganged' pot). 6 SETUP LOGIC INPUT DEFINITION SCREEN Up to 24 contact-closures may be connected to the Logic Inputs port of the RCU. Contact-closures may be switches, relays, or logic outputs from other devices. Each logic input may be programmed to perform a specific control function for a specific product. This programming process is performed using the "Advantage Device Control Function" section of the Logic Input Definition Screen. Each product that is linked to the RCU must have a unique device number. When creating a logic input definition, you must specify the device number of the product which that logic input will be controlling. Once you have specified the model, a list of available operations appears in the "Operation" list box. The list of operations changes depending upon which model is selected. When a definition has been established for a particular logic input, an icon and device number will appear above the `LED' indicator on the Main Screen. The icon and device number indicate which device the logic input is programmed to control. When the mouse pointer is positioned over the LED indicator, a pop-up `hint' appears which provides a detailed description of the function which the logic input is programmed to perform. In addition to specifying which actions occur when a contact closes, you also may specify which actions occur when a contact opens. Normally, each of the 24 logic inputs acts independently of the others. [. . . ] For best performance, the PC ground and the chassis ground of the RCU should be at the same potential, and the PC should get AC power from the same source as the RCU (and any other audio equipment which is connected to the RCU). Since most lap-top computers are isolated from earth ground, this should rarely pose a problem. Serial Port Data Communications Parameters: The RCU communicates through the Serial Port at the factory selected rate of 9600 bits per second, with 8 data bits, 1 stop bit, and no parity. The eighth data bit of each character (the most significant bit) should always be 0. [. . . ]
