User Interface
All DMX 6-PORT MERGER models are equipped with a user interface located on the front
panel of the enclosure. The user interface provides access to all programming and conguration
settings. System status is easily visible on the LCD display and LED indicators.
LCD Display Programming Switches Status LED Indicators
All of the programming is accomplished using four (4) switches. Within a few minutes, most users
will nd the menu structure very intuitive and easy to navigate. All conguration settings are
automatically stored into an on-board EEPROM.
LCD Display
The LCD display is capable of displaying 2 lines of 8 Characters. A backlight automatically comes
on when activity is sensed on the switches. The LCD contrast can be easily adjusted for optimum
viewing. Refer to menu item “LCD VIEW” on page 18 for further details.
Programming Switches
The MENU UP/DOWN ( ) switches are used for navigating through the various system
conguration menu items. They also allow for programming of other specic parameters within
a selected menu. Pressing and holding either switch will speed up the scroll rate, which can be
helpful to speed up the conguration time.
The EXECUTE ( ) switch is normally used to select/enter a menu item, advance forward within
a selected menu item, or toggle between parameters within a selected menu item.
The ESCAPE ( ) switch is normally used to back up within a selected menu item one step at a
time or exit the menu completely.
14
NOTE: The programming switches can be locked out to prevent inadvertent conguration
changes. To toggle between “LOCKED!!” and “UNLOCKED” press and hold down the
EXECUTE and then ESCAPE switches at the same time for 4-5 seconds.
The RESET switch has two purposes. First, it allows for quick exit from a menu item after a
programming change and automatically puts the system into normal run mode. Second, it
provides a soft reboot for the systems microcontroller.
The programming switches are backlit with blue LED’s. The LED’s automatically turn on when
activity is sensed.
NOTE: A detailed procedure for programming all system conguration menu items can be found
on pages 16 to 18.

USB Tech Port Operation
The Tech Port is used to connect to a PC via USB. Emulation software
such as PowerTerm® may be used to monitor/view the DMX channel levels
received on each of the DMX input ports, as well as the DMX channel levels
transmitted on the DMX output port. Other diagnostics such as status, packet
size, packet rate can also be viewed.
PowerTerm® Lite is the PC emulation software recommended by the factory.
Other software that emulates VT52 may be used, but is not advised or
supported in this manual.
PowerTerm® Lite Specications: http://www.ericom.com/specs/Lite_Plus.pdf
Buy PowerTerm® Lite Online: https://www.ericom.com/BuyNow/default.asp
Once PowerTerm® Lite has been downloaded and installed on a PC,
it is very important to set it up correctly to communicate with the host
DMX 6-PORT MERGER.

USB Driver Information
When the USB Tech Port is rst connected to a PC, the PC will automatically try to
nd a driver. It is unlikely to nd a driver automatically, so the applicable USB driver
will need to be downloaded and installed.
The USB interface chip (FT245R USB FIFO) on the DMX-6PM controller board is
manufactured by FTDI (Future Technology Devices International) and requires an
FTDI driver loaded on the same PC as the PowerTerm® Lite software.
The driver type required is VCP (Virtual COM Port). The VCP driver makes the USB
device appear as though it is connected to a COM port.
1. Select the applicable driver to download from the following link:
http://www.ftdichip.com/Drivers/VCP.htm
The driver download is a ZIP archive folder named: CDM 2.08.28 WHQL
Certied. Save it in a convenient location.
2. Create a folder in a convenient location (recommend C:\FTDI Driver), and
extract the ZIP archive folder contents to the newly created folder.
3. Connect the USB Tech Port to the PC. The “Found New Hardware Wizard”
automatically pops up. Select the “Install from a list or specic location
(Advanced)” option and click “Next” to continue.
