System requirement

1. PC AT

2. Windows 95

3. Two serial connection cables RS232(M/F)

Equipment

1. Interface board(3122 785 90200)

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.

Flashing the MACE

1. Connection

• 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.

• 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.

• Connect the interface board with the mainboard via connector 1818 and the mains

powersupply of the set. Via the connection 1818 to connector 1000 the interface has
been powered by +5V.

• The connection between connector 1015 and the 5 solder islands (in line) on the

mainboard (bottomside) can be soldered.

• Connect 1015-1 to F451,

• Connect 1015-2 to F450,

• Connect 1015-3 to F453,

• Connect 1015-4 to F452,

• Connect 1015-5 to F454.

Note: the measuring points F451, F450, F453, F452 and F454 are the 5 islands in row
located at the left side of the mainboard, seen from front (tray-opening) side of the
module. F454 is mass connection.
