Yamaha CS1D Service Manual page 111

• Explanation of PM1DLOAD screen (when Advanced = 1)
* The usage precautions are the same as when ADVANCED=0. Refer to "Installation Directions" in the "PM1D SYSTEM SOFTWARE".
2. Properly set the serial port/ connection point.
However, during Card Direct, the connection point
setting has no relation.
1. Select the connection method.
* If Host I/F•••CS1D or DSP1D serial port is used
* If directly connected to HP connector for each
CardDirect sheet.
• Method for writing firmware using the DSP1D RS232C port
* It is possible to write the CPU firmware from the PC via
the RS232C port. This is the method normally used.
* Refer to "Installation Directions" in the "PM1D SYSTEM
SOFTWARE" for precautions and other such warnings.
1. Install and set PM1DLOAD with the methods above.
2. At the very least, connect as shown in the figure above (when CS1D). If it is not possible to avoid making signal connections
other than these, turn off the power supply for all components other than those relevant to the write object and turn off the
control power supply for the volume of other components such as speakers and amplifiers.
3. Turn on the power for the write object and start PM1DLOAD. (CS1D is shown in this example.)
4. After starting the PM1DLOAD, select the Host I/F with MODE SELECT, then press OK.
Use the setup menu to set the serial port. (Refer to "Installation Directions")
5. Select CS1D from the pull-down menu. (CS1D is shown in this example.)
6. Select the names of all the desired firmware, then press Write. The pieces of firmware can be selected individually if necessary,
but in that case all the firmware must match the version included in the PM1D system software. (For details, refer to the
individual test program specifications.)
* "Boot" is displayed in the name display unit on the INPUT, SELECTED INPUT, SELECTED OUTPUT,
MASTER, and METER panels to indicate the write ready state.
7. When the writing is complete for all the units, switch the power off, then on again.
8. Press the GetVer. button and check that all the units have the appropriate versions.
9. If the writing is to DSP1D/AI8/A08, connect and set in the same way and then repeat from Step 2.
10. Once the write has been completed, end PM1DLOAD.
• Method for writing firmware directly to each sheet
* When there is some kind of problem and the firmware can not be written with the method on the previous page, use
the method below.
CS1D
For INCPU, ISCPU, OSCPU, MSCPU, and MTCPU
The connection port for DSP-CHECK is a 10/12-pin PH connec-
tor, so use a cable with the specifications below.

5. Check the firmware name desired for writing.
All checks them all.
Clear removes all checks.
