Installing SYEMB06 Modules In Your SY85 / TG500 / RM50:

STATIC ELECTRICITY PRECAUTIONS
Before handling any type of electronic PCB you must be aware of the dangers of static electricity. Static electricity builds up in your body when you walk around on carpet and other flooring materials. Your clothing generates static when you move about. When you remove certain types of clothing you hear 'clicking' or even see sparks in a darkened room - that's static electricity! Although static is harmless to humans it is VERY BAD for electronic components - if it jumps from you to any electronic PCB you will surely cause damage to the electronic components mounted on it.

To eliminate static electricity problems we recommend you use an anti-static wrist strap. This will look something like the photo below:
Anti-Static Wristband

The cloth loop goes around your wrist and the crocodile clip connects to the nearest earthing point. Earthing points you can use are the outside of your PC's metal case, water pipes, or any other electrical appliance casing that you know is earthed.

If you don't have an anti-static strap you can discharge static from your body by touching any earthed case or water pipe before handing anything electronic. Try not to move around too much and keep touching the earthing point from time to time.


INSTALLING THE MODULE
The module will come supplied in a static shield bag. This bag keeps the module safe from static harm but is vunerable once it leaves the bag. Do not touch any of the components on the board and try to hold the board by the edges only.

Before installing a module in your Yamaha unit please backup the internal memory. After a module is installed you will need to initialize the sample memory and this may initialize the patches. It is highly recommended to backup all your settings and patches before proceeding!

To backup your unit's settings and patches over MIDI please use the C6 Utility availiable for free from Elekton's website HERE.



The installation procedure below is for the SY85
.. but it is pretty much the same for the TG500 and RM50.

Note that the RM50 was only one module connector.


STEP 1: Remove the expansion cover.

SY85 Expansion Cover
Using a Philips or 'starhead' screwdriver remove all 6 screws from the cover.

This will reveal the memory expansion connectors. In the photo below the Non-Volatile connectors are arrowed on the left, and the Volatile SIMM connectors are on the right. In this SY85 there are two 4MB SIMMS already installed thanks to Saul from YamahaForums :-)

SY85 trivia: The internal 6MB waveform ROM lives in the 3 chips to the left of the Non-Volatile connectors, and the onboard 512KB Volatile memory lives in the four chips under the bottom SIMM.

Expansion Connectors



STEP 2: Note orientation of the connectors.

FX2 Connectors

The Non-Volatile connectors on the motherboard are a 'D' shape and this ensures the memory modules will only fit in the correct way round. Note the two arrows pointing to the PCB markings (1) and (2) - if you are installing just one module you must locate it in connector 1 - it will not work in connector 2.



STEP 3: Inserting a module (or two).

Carefully remove the module from the anti-static bag and hold the module like
this..
Module 1


Place the module's connector over motherboard connector (1) and with a finger either side of the module's edge gently push the module fully into the motherboard connector. Module 1 Inserted


If you are installing two modules place the second module over connector (2) and push it gently into the connector.
Module 2 Inserted


When viewed from the other side of the connector panel the modules and SIMMS will look like this:
Installed

Now replace the panel cover and the 6 screws - the installation procedure is finished!
