the PC’s administrator to install Crossmax.
Installation from DC-ROM drive:
·
Insert the CD into CD-ROM drive
·
Run the setup program ( “xmax_300.exe” )
·
Follow the setup notes
3. Connection PC <-> Unit
Generally, the editor software runs without the need of a DSP 244 being
connected. For remote controlling a DSP 244 via PC please observe the following
steps when establishing the connection:
RS-232-Communication:
·
Examine which of your computer's COM-ports is
accessible and not assigned to another application or external device. Crossmax
allows to select COM1 to COM8.
·
Use the supplied serial cable to connect the chosen
COM-port and the RS-232 port on the DSP 244. In case the COM-port of your
computer is not carried out as a 9-pole D-sub connector, please consult your
local supplier for computer accessories to get a fitting adapter.
·
If you have not COM port on your computer, it is
possible to use USB to RS-232 converter to communicate with the device. In that
case, you need to examine on which COM-port is converter installed and select
that port for communication. Use the serial cable to connect the device and
converter, and another cable to connect the converter and PC.
RS-485-Communication:
·
Make sure your units have installed a
firmware version 2.01 or higher. If not, you have to update the firmware using
RS-232, first !
·
Make sure that you have installed the RS-485 board in
your DSP 244 unit(s).
·
Examine which of your computer's USB- or COM-ports is
accessible and not assigned to another application or external device. Crossmax
allows to select COM1 to COM8.
·
If you use a USB / RS-485 Converter connect it to the
USB-port. In Crossmax choose RS-485-Setup in the Remote-Menu and select
the COM-port assigned to the USB / RS-485 Converter. (Read more about USB / RS-485 Converters in chapter 6)
·
If you use a RS-232 / RS-485 Converter connect it to
the COM-port. In Crossmax choose RS-485-Setup in the Remote-Menu and
configure the COM-port due to the converter’s manual.
·
Connect the RS-485 converter with the RS-485 port of
the unit(s). If you have the DCN 485 you can use a standard twisted-pair
Microphone-Cable. The DCN 485 is powered from a PC’s standard PS/2 port.
Connect the converter’s PS/2 plug to a free PS/2 socket of your PC. If all your
PS/2 ports are in use already (e.g. for the keyboard or mouse) you can then
plug the keyboard or mouse to the DCN 485.
·
Make sure, that the units’ RS-485 IDs matches with the
software’s RS-485 IDs. Otherwise the communication won’t work.
MIDI-Communication:
·
Connect the PC's MIDI-Out port with the unit's MIDI-In
port and vice versa. Be aware that both cables have to be connected, otherwise
you'll get a "Communication Error".
·
Make sure, that the unit’s MIDI Rx channel matches
with the software’s MIDI Tx channel. Otherwise the
communication won’t work.
4. Sending a new firmware to the unit
Crossmax comes with the latest firmware. After installation, the
firmware can be found in the folder “Crossmax\OS”. Generally, it is strongly
recommended, always to use the latest version of the firmware. This chapter
describes, how to send a firmware to the unit. Your User Presets will not be
erased !
·
Check out our homepage for the latest firmware and store
it in the "OS"-directory that has been created, when the Editor was
installed.
·
Unzip that file, also into that
"OS"-directory.
·
Connect your PC with a single unit via RS-232 or to
several units via RS-485 as described in chapter 3.
·
Start Crossmax
·
In the "Remote"-Menu, select "Send
firmware to unit" and choose "RS-232" or “RS-485” in the
additional menu, that will pop up.
·
Choose the appropriate firmware-file by
double-clicking it and follow the messages that will appear on the screen, now.
The display of the unit keeps clear while data-transfer.
When sending a new firmware to the unit and this process fails or has
been interrupted, the unit may not work anymore. In that condition, the unit
starts up in a so called Bootload-Mode. The Display
stays clear in that mode! Please check all connections to be done. Then turn
the unit off and on again and try again to send the firmware. If even that
doesn't help, please contact EVI Audio.

6. Important Notes
6.1 USB-Interface to Serial Port Converter’s
There are two serial ports available for the
units – a RS-232 port as standard interface and a RS-485 port as optional
interface. The RS-232 interface should be used when controlling just one unit
and for short cable runs. The RS-485 interface should be used when controlling
more units (up to 31) and for long cable runs as it is a balanced interface.
To accommodate the possibilities on current
computers, we support both USB-to-RS-232 and USB-to-RS485 interfaces. For
USB-to-RS485 converters a PC software version V2.10 or higher is needed.
A) USB to Serial RS-232 Interface
This interface provides a RS-232 port from a USB
laptop. The following converters have been tested successfully with PC software
versions V2.06 and higher:
VISION SYSTEMS Vscom USB-COM, USB Serial Adapter
VISION SYSTEMS Vscom USB-2COM, USB Dual Serial Adapter
VISION SYSTEMS Vscom 232 PCMCIA, PCMCIA Card with 2 RS232 ports

B) USB to Serial RS-485 Interface
This interfaces provide a RS-485 port from a USB
laptop. The following converters have been tested successfully with PC software
versions V2.10 and higher:
ICPCON I-7561 USB to RS-232/485 Converter
This is a converter for transferring serial data
over USB. It allows you to connect your serial devices to a PC USB interface
and it provides a RS-232 port and a RS-485 port within one converter. The
output ports are provided on barrier strip terminals on the box. The wiring diagram
below shows the pin assignments for RS-485 and for RS-232 interface cables.

More ICPCON information can be found at:
http://www.icpdas.com/products/7000/i-7561.htm
VISION SYSTEMS USB-COMi-SI USB to RS-485 Converter
This is a converter for transferring serial data
over USB with optical isolation. Connecting to a USB port on your computer it
provides a serial RS-485 port on a DB9 male connector. The following drawing
shows the interface cable from DB9 to XLR.

More USB-COMi-SI
information can be found at:
http://www.visionsystems.de/produkte/623.html
The solutions outlined above have been tested
with PC software version V2.10 on Windows 98, 2000 and XP. Other interfaces may
work also, but these are the ones we have tested and would recommend. If you
wish to use a different interface, or are a manufacturer who would like to
supply a unit for evaluation, please contact us.
6.2 Disabling the
FIFO-Buffer ( when using DCN 485 Converter ):
For the RS-485 communication to work proper with the DCN 485 Converter
it is necessary to disable the COM-Port’s FIFO-Buffer
Win 95/98/Me:
Win NT:
Win 2000:
Win XP:
6.3 Encoder Type
In some cases, a problem due to the encoder may occur when upgrading the
firmware to a version newer than 1.02. If the encoder behaves wrong and needs
two steps for one value increment or decrement, you can get rid of that problem
by stepping through the service procedure as described in the following:
·
Press the right SELECT button and the EDIT button
simultaneously while switching power on. The unit will start in the SERVICE
MODE.
·
Step through the test menu using the SELECT button
until you get to "ENCODER TYPE".
·
Push RECALL, the unit will show "STEPS/DETENT
1" or STEPS/DETENT 2".
·
Change with encoder to the different selection
"STEPS/DETENT 1" or STEPS/DETENT 2", respectively.
·
Press RECALL again and turn off the unit.
When turning the unit on again, the encoder should work the way it is
supposed to.
6.4 Appearance
If Crossmax does not look the way it is supposed to, you may have old
windows system files in your PC. Please launch the "40comupd.exe"
file located in your Windows-System-Directory.
7. Crossmax Revision History
Version 3.00
·
In order to protect equipment , synchronization
between PC and Device is now under the following rules :
1. Remote control of an existing PA system:
Open Crossmax and select “RS-232 Remote”
or “RS-485 Remote from the File menu. When going online with RS-232 or RS-485,
data will always be sent FROM DEVICE(s) to PC.
2. Configure a PA system with existing project data from
PC:
Start Crossmax and open an existing
project file in the File menu. When going online the first time, data will be
sent FROM PC to DEVICE(s) and stored in User Memory 30 by default. The User can
select another memory location in the online dialogue. After that, if the user
goes offline and then online again, data will be sent from DEVICE(s) to PC. If
user wants to send data one more time to device(s), the opened project must be
saved and closed, then opened again. Then, by going online, user can send data
to unit(s) again.
3. Create a new project file:
If the User creates a new project, then is
not possible to go online immediately. The new project must be saved, and then
it will be treated as existing project. In this case, synchronization is like
in previous case, of course.
·
