Warning: Do not mismatch the polarity of the power supply. False connection may
damage the device
.
Important: Make sure that the reference input is always connected, because signals applied to the reference
input are subtracted from the recording signal input channels. If the reference input is unconnected or
connected to an electrode in an active area (for example, it sees signals of interest), this will either lead to
signal loss or to a very high noise level. Connect the reference input to the ground of the setup when you
are not using a reference. For more information, please see Differential Amplifier and Noise Reduction.
1. Place the PGA on a stable surface, where the air can circulate freely and the PGA is not exposed
to direct sunlight.
2. Connect the input signal source, for example, a SC8x8 or SC2x32 signal collector connected
to miniature preamplifiers, to the
68-pin MCS standard input connector of the PGA.
3. Connect the 68-pin MCS standard output connector to the MC_Card input of the data acquisition
computer by a 68-pin MCS standard cable. Make sure the IPS10W as a power supply source is
properly installed to the data acquisition computer. Check the output power if you are in doubt.
For more information, please see the ME-Systems Manual.
4. If the data acquisition computer has no IPS10W, connect a suitable power supply, for example
a PS40W, to the 4 mm power input sockets. An internal power supply transforms the supply voltage
into the internal supply voltage.
5. Connect the USB connector to a free USB 1.1 port of the computer with a USB cable Type A - B.
The connector on the PGA side is type B; the connector on the computer side is type A.
The computer connection is necessary for programming the PGA, but not for operating it.
6. Switch on the PGA. The LEDs on the rear panel must light up, otherwise the power is insufficient.
7. Install the PGA-Control program provided together with the PGA to the connected computer.
The PGA driver is installed automatically as well.
