II, digital display
The current mode of operation set, press any number key 0-9, showing the corresponding figures, the number of consecutive input sequence shown, but only display the last 5 digits, according to the number 0 next to the Cancel button, equivalent to BS (back delete) function, remove the lowest, according to the other any key to display clear. Digital display that prompts the current operation is only the number of streams.

III, voice prompts
Press any key (keyboard or control analog amplifier) will have voice prompts.

IV, amplifier control
Volume. Tone. Mixing and Mike Class IV control parameters, which built a nine pitch control code (B4-B1, $, # 1 - # 4) and single-I, b, and # of features, you can achieve very comprehensive control. Volume and mix Mike the reset button and retain the standard key functions, the need for specific expertise to do the adjustment amplifier can be achieved, because of their hair the same key control parameters for adjusting the speed amplifier is not I like.
Control panel of the EEPROM memory, of which several X bytes is set for the power amplifier control, storage of the power amplifier device code (devicecode) and I keys for each command code (commandcode), details see the company's Universal infrared control technology.

V, keyboard code table
Control panel of the EEPROM memory, which I more than 100 bytes is flexible and change the code table and set the keyboard, including the most downstream of the alphabet can also be flexible to change, for example, a defined ctrl-a.

VI, interface description
From the control panel on the back to see (corresponding to the positive circuit board, that is, surface components).
On the left most bottom corner is DCIN, DC power input terminals, voltage range 11v-15v, current is not less than 500ma, the board has two independent regulator modules, respectively, to adjust into a luminous +9 v DC power supply module, into the +5 v regulator to other circuitry.

On the left of the middle two PS / 2 socket KB1 and KB2 can add two PS / 2 keyboard type input device, such as the general keyboard. Small keyboard. Remote control keyboard and so on.
Left on top of two RJ45 Network Block NETC1 and NETC2 other control functions for future expansion while setting the current to retain function.
The right most bottom corner is KB, direct into the computer's PS / 2 keyboard port, because the use of the external power supply, no need to take power from the computer keyboard port, so the keyboard port of the power cord and control the other circuit board power cord is disconnected , because the luminous driver module needs to +9 v v DC reverse into hundreds of alternating current, current consumption is large easy access from the computer keyboard port power directly.

If you do not glow driver module, you can directly use the computer keyboard port of the power supply, the PS / 2 interface, I left next to a 2pin to link the short-line interface, you can take power from the computer keyboard port.

The right side of the middle coordinate for the DB9 COM, that is designed for the computer serial communication, which means that the control panel can also be customized into a com interface, but the ps / 2 keyboard interface and com interfaces can only choose the I, order time is not specified is ps / 2 keyboard interface. Com control panel interface and the computer's com interface definitions are identical, making cable III when only the root line RXD \ TXD \ GND, Note transceiver line RXD \ TXD to cross. PIN2 to RXD.PIN3 to TXD.PIN5 to GND, which is PC-type serial port DB9 standard definition.

Block RJ45 network port on top of a small power supply for external power control devices designed, for example, call control services, equipment, etc., if the definition line by order from top to bottom, then 1 to +5,2 to GND for the circuit board to the external device power supply terminal, 7 and 8 for the relay normally open terminal, the other idle. Now to preserve function.

Block the top right of RJ45 network cable for the IR output control designed, if defined by lines from top to bottom order, then 2/4/6/8 ground infrared emission is the negative control, 1 and 3 is the infrared output terminals connected infrared emission cathode tubes, but only 3 valid, that is, then I just fired infrared tube.
