3.2 Setting Up and Connecting the STG
Note: You can use a USB hub for connecting the STG to the computer, for example, if you have
no free USB port or if you need to extend the USB cable.
Do not use a hub in Streaming mode! Please note that if you want to use the STG in
Streaming
mode, you cannot connect a second device that sends or receives continuous data streams, for
example a web cam or USB speakers, to the same USB port, because the STG needs a broad
bandwidth for the data transmission.
This does not matter if you want to use the
Download mode (via MC_Stimulus II or custom
program) only.
Provide a power supply and a computer with USB port in the immediate vicinity of the
installation site. Make sure the STG is switched off before you connect it to the power supply.
1. Place the STG on a stable surface, where the air can circulate freely and the STG is not exposed
to direct sunlight.
2. Connect the external power supply to the STG.
3. Connect the external power supply to the power outlet.
4. Connect the USB connector to the USB port of the computer. The computer connection
is necessary for programming the STG, but not for operating it (except in Batch mode).
5. Connect the + and - plugs of the required output channels with 2 mm plug cables to the
stimulating electrodes. Connect the appropriate ground to the ground input of the stimulation
setup, for example, to the ground input of the MEA1060 amplifier. Current and voltage driven
stimulation is generated from the same outputs.
6. (Optional) Connect the required Trigger In inputs with BNC cables to instruments that produce
TTL signals for triggering the STG.
7. (Optional) Connect the required Sync Out outputs with BNC cables to following instruments
that you want to be triggered by TTL signals from the STG, for example to one of the 16 digital
inputs of the MC_Card.
8. Switch the STG on by pressing the toggle switch on the rear panel.
Note: It is recommended to start the STG ten minutes before use to allow warming up!
