Setting up the Hardware
Recording and stimulation hardware connected to your computer will be detected automatically.
If you have more than one stimulator, you can select one of them with the drop down menus.
Here you also find the menus to specify the layout of the MEA chip and control the blanking.
From the drop down menu "Layout", please choose the correct layout for your MEA chip inside
the MEA amplifier. The data display will change accordingly. While working with only one STG,
there is no need to set the drop down menu in "STG", but you always have to set the COM port
for the MEA amplifier in "MEA-BC-Port" drop down menu. If you are working with multiple
devices parallel, you have to specify the COM ports to which the actual STG and MEA amplifier
are connected. The "MEA-BC-Port" drop down menu shows all available COM ports of the data
acquisition computer. Please choose the port, to which the MEA amplifier is connected.
The "STG” drop down menu shows all available STGs, please select the actual used device.
The window beneath will display the status. Now you can activate or deactivate the blanking.
A stimulus generator is one of the requirements for applying the software, because the
LTP-Director cannot display spontaneous data, but only triggered sweeps of 100 ms length.
That is, why "STG" has to be correctly connected, too. There is an error message, if STG or
MEA amplifiers are not accessible from data acquisition computer.
For common experiments using a MEA1060-BC amplifier with blanking circuit, the function
"Blanking" may be selected or not. Using a MEA1060 amplifier without blanking circuit,
the "Blanking" option is disabled.
Important: It is possible to switch the blanking mode while the data acquisition is running!
