Welcome to the LTP-Director

Software Settings
Start up to four instances of LTP-Director, and configure the settings independent of each other.
Click Hardware tab in main menu "Settings".
You can select all hardware settings in the hardware dialog for each instance separately.
The serial number defines which device is controlled by which LTP-Director instance.
The LTP-Director software assigns the settings of the different instances to the connected device.
Thus, you can run completely independent experiments with up to four USB-MEA32-STIM4
amplifiers.
In the Control Window of the Test Mode the hardware configuration and the number of the
current instance are displayed. Select the correct MEA layout from the drop down menus. When
working with USB-MEA32-STIM4-Systems, the drop down menus for the selection of the STG and
the MEA-BC Port have no function and are disabled because of the internal amplifier and the
internal stimulus generator.
The LTP-Director software supports typically voltage driven stimulation. With USB-MEA32-
STIM4-System the current driven stimulation of the integrated four-channel current stimulator
is supported as well.
Important: After setting up the complete system with multiple instances of LTP-Director,
please check the gain settings of each single instance! May be the gain setting (1000)
is correct for the first instance, but incorrect for the following instances, when starting
the system for the first time.
