2. Adapter cable included with 3122 785 90200 for communication with CDR module
3. 5 fold connection cable between interface board connector 1015 and solder islands for
Mace download connection. (not a normal service part)
4. Software package(cdrflash.exe)
Info
With the interface board 3122 785 90200 you can also update the third generation CDRecorder.
Two procedures have to run for updating MACE- and DASP-flash ICs. These procedures are
described in chapter “Flashing the DASP” and chapter “Flashing the MACE”
Setting up the PC
1) COM ports
To get the right settings for the communication ports do the following:
Open with Start → Settings → Control Panel the window Ports. Select a port and
click the Settings button. Change the settings in:
Settings for COM1 and COM2:
Baud Rate : 19200
Data Bits : 8
Parity : None
Stop Bits : 1
Flow Control : None
For the communication with the DASP we are using PC ports COM1 and COM2. In
this case connect COM1 with connector 1010 (also used for Compair communication)
and COM2 with connector 1011 on the interface board 3122 785 90200.
For the MACE communication we are using also COM2. Therefore connect then
COM2 with connector 1014 on the interface board 3122 785 90200.
In case your PC has 3 com ports COM3 can be applied. Settings for COM3 should
then be as COM2.
Does your PC have only 2 (two) com ports then the connection from COM2
has to be changed after the downloading of the DASP and make the connection for
MACE.
