INTRODUCTION
About
The DXB-8 is a low cost 8 button single gang button panel. Designed to work with just about any RS-232 device on the
market, the DXB-8 allows any RS-232 string to be assigned to the press and release of each button. Advanced
functionality is available like repeat on hold. Toggle, macro (delay between multiple commands), and interlocking buttons
for transport controls, power on/off, etc.
The buttons can individually be lit red, green, or blue so in dimly lit areas it can be seen. There are over 60 different laser
etched button types available as well as custom laser etching. Available in Decora®white or black, the DXB-8 is designed
to match.
Low cost, low power, simplicity, and compatibility with just about any device on the market makes the DXB-8 the simple
sweet solution of choice.
Features
8 Backlit Buttons (Red, Green, Blue)
Fits in Standard 1 Gang Decora®Style Outlet
2 RS-232 Ports
Buttons Individually Programmable for RS-232 Command
Programmable on Press, Release, Toggle, and Hold
Macro Functions and Interlocking Buttons
9600 –115k Baud Rate Selectable
Designed to Work seamlessly with DXW-2 Series
Customizable Laser Etched Buttons
Daisy Chain up to 8 Units for Multi-Gang Button Panels
Low Power
5v DC Powered

DXB-8 Front
Front
Buttons: There are 8 backlit buttons, ON, OFF, VGA, HDMI, Up Arrow, Down Arrow, Speaker Mute, and Mic Mute.
These laser etched buttons come as a default with the DXB-8. Other customizable buttons are available. The LED
backlighting can be set to light red, green, or blue.
The default scheme is to match the DXW-2 wall plate series to remotely select the inputs and to also control the display.

DXB-8 Rear
Rear Connections
RS-232 1: Connect RS-232 device up to 115k baud. Note there is a 5v line as it is designed to power the DXB-8 from
the DXW-2 wall plate or an option 5v supply for stand-alone operation with any RS-232 device.
RS-232 2: Connect RS-232 device up to 115k baud.
Units can be linked together to create larger button arrays by feeding port 2 of first unit into port 1 of next unit in line. By
repeating this process from unit to unit, the commands can pass through from one the next. Make certain to “null” the TX
and RX. In other words TX should go to RX and RX should go to TX from unit to unit. The RS-232 protocol is designed to
communicate to the address of a specific unit so it is important to make certain each unit has a unique address and the
same baud rate.

APPLICATION
DXB-8 Controlling DXW-2EU and Projector
The example below demonstrates the DXB controlling a DXW-2 series wall plate which in turn passes the RS-232 to the
DXE-CAT series receiver. The DXE-CAT receiver RS-232 port is connected to the projector.

BUTTON SETUP FUNCTIONS
Button Setup
Buttons are referenced 1-8 starting in upper left to lower left for 1-4 and upper right to lower right for 5-8.
Unit Address: Holding buttons 1 and 4 down for 5 seconds will allow user to press button 1 through 8 to set address
accordingly. When the 5 seconds is reached, current address will show by blinking button relative to address blue.
Next user will press any of the 8 buttons to set new address. Once button is pressed, a confirmation will happen by
flashing new address buttons LED RED, then green then off as it exits the mode of operation.
Factory Test: Holding buttons 5 and 8 down for 5 seconds will do factory test. Factory test is light all buttons Red for
2 seconds, Blue for 2 seconds, and Green for 2 seconds. Next, it will blink a red LED starting at button 1. When
pressed, next button in order will blink red and prior button will turn off until all 8 buttons are pressed. After button 8 is
pressed, unit will finish with RS-232 loop test from port 1 to port 2 to verify back and forth communications. LED 1 and
2 will light blue and pressing button 1 will send string from port 1 to 2 and pressing button 2 will send string from port 2
to 1. During both, it checks for proper response. Send string !test<cr> to be responded with ~test<cr>. If it checks
okay, LED 4 will light Green for okay or Red for bad for port 1. Use LED 5 for port 2 indicator. Once Port 2 test is
done, light blue LED 8 and when pressed End factory test mode by turning on all 8 LEDs blue for 1 sec then off.
Factory Reset: Holding buttons 3 and 4 down for 10 seconds will do a factory reset. Factory reset will set RS-232
ports 1 and 2 to 96008N1, Unit address to 1, and assign strings on push for !1B1<cr> for button 1 and increment
accordingly for all 8 button. The release will be set to !1R1<cr> for button 1 and increment accordingly for all 8
buttons. Hold will have nothing. All LED will be defaulted to blue for press and release.
Update Mode Port 1: Holding buttons 1 & 8 > 5 seconds will force unit into firmware update mode via port 1.
Update Mode Port 2: Holding buttons 4 and 5 > 5 seconds will force unit into firmware update mode via port 2.
Daisy Chain Mode: Holding buttons 4 and 8 for 2 seconds will enable daisy chain mode. After 2 seconds, all button
LEDs will go off for 1 second then LEDs 1, 4, 5 and 8 will light for 1 second, Red for daisy chain mode or Green for
normal mode then all LEDs return to their normal color.

DXB-8 Daisy Chain Mode
The DXB-8 units can be combined (up to 8 total), allowing multiple units to function as a single control interface. All
commands when operated in this mode pass through to com1 of unit1. The last unit in the chain must always be address
8 in order to connect a device to communicate with port 2. The !8PD,z<cr> (z = string) command must be used to target a
command out this port (see RS-232 command section for proper usage). If you are not using the last port in the chain
then it will not be necessary.
Daisy Chain Mode
Holding buttons 4 and 8 for 2 seconds will enable daisy chain mode. After 2 seconds, all button LEDs will go off for 1
second then LEDs 1, 4, 5,and 8 will light for 1 second, Red for daisy chain mode or Green for normal mode then all LEDs
return to their normal color.

PROGRAMMING SOFTWARE
DX Interface
DX Interface is a free utility for programming the buttons with the various functions. It allows a user to assign RS-232
strings and LED color selection to the different button states. These assignments can be applied to the push, release, and
holding of the buttons. Refer to Appendix 2 for cable connection to a PC. DX Interface is designed to run on a Windows®
PC. The latest versions of DX Interface can be downloaded from www.auroramm.com.

BUTTON CAP SELECTION
Button Caps
The DXB-8 buttons are removable and can be replaced with a variety of buttons listed on the chart below in white or
black. For caps not listed on the chart custom laser etched button caps are available for a one time processing fee to
accommodate any install. Check with [e-mail] for more information.
DXB-8 Button Cap Selection Chart
Buttons can be reversed 180o.
*Note: Part Number = DXB-C[Row#][Column Letter]-B/W (B = Black / W = White)

APPENDIX 1
Troubleshooting
Problem
Solution
1. LED is not lit on any buttons
a. Check 5v power supply is plugged in locally or if connected to DXW-2 make
certain the DXW-2 has power.
b. Check to see if Wall supply is plugged into wall outlet.
c. Make certain wall outlet has power.
d. Make certain RS-232 command for LED state is not set to none for the
buttons.
2. RS-232 does not work
a. Check connection on RS-232 port. Make certain TX goes to RX and RX
goes to TX of the device to be connected. Do not forget about ground.
b. Check baud rate.
c. Verify commands being sent are correct protocol.
d. Each unit must have a unique address.
3. Some functions do not work
a. Make certain unit has latest firmware.

Firmware Update
DXB-8 Update Utility
DXB-8 Update Software requires a serial cable connected in a null (RX to TX, TX to RX, GND to GND) configuration to a
PC. The firmware can be updated directly at either of the DXB-8 rear serial ports. To force update mode holding buttons 1
and 8 for 5 seconds will force unit into firmware update mode for port 1 and holding buttons 4 and 5 for 5 seconds will
force unit into firmware update mode for port 2. LED 1 will light blue when in the mode for port 1 update and LED 2 will
light blue when in mode for port 2 update. A way to force update if necessary is to hold buttons 7 and 8 while applying
power to the DXB-8. Next, use utility to transfer file which can be found at www.auroramm.com.
