4.4.1 Operating multiple MEA Amplifiers with one STG
It is possible to operate more than one MEA amplifier independently with a single stimulus
generator of the 4000 series. To do this, activate the Independent Channel Download feature
in the Settings menu of MC_Stimulus II.
This feature will allow to download new stimulation paradigms to individual channels without
interrupting the ongoing stimulation on other channels. See chapter “Downloading Stimulus
Files” for more information.
It is mandatory that all stimulation and Sync Out channels that are associated with one amplifier
are assigned to the same trigger in the Trigger Settings menu. For example, if four MEA1060-
BC amplifiers are connected to one STG4008, usually two stimulation channels and one Sync Out
are associated to each amplifier. In that case, the trigger settings should be as shown:
Amplifier A is connected to stimulation channels 1 and 2 and Sync Out 1, Amplifier B
is connected to stimulation channels 3 and 4 and Sync Out 2, and so on. All channels
connected to one amplifier are assigned to the same trigger.
To download a stimulation paradigm to individual channels assigned to one amplifier only, select
all channels connected to this amplifier in the “Download Channel” check box (1 and 2 in this
example) and Sync Out 1 in “Download Sync” check box, whether you changed them all or not!
Only these channels will be downloaded, ongoing stimulation on other channels will not be
interrupted.
