Intan CLAMP System
CONFIG switches: Configuration switches 1-3 are reserved for future use. Switch 4 (CONFIG4) is used to select the
•
voltage level of the digital output ports (see next item). With CONFIG4 in the down position, 3.3V digital signals are
generated. With CONFIG4 in the up position, 5.0V digital signals are generated.
Digital outputs: Two BNC sockets produce either 3.3V or 5.0V digital signals (see previous item) that can be
•
synchronized with software-generated voltage clamp or current clamp waveforms.
USB port: A USB 2.0 port provides two connection to a host computer running the control software.
•
Sample clock out: This port generates a digital square wave proportional to the headstage sampling rate when the
•
headstages are active. While the software acquires data with a sampling rate of 50 kS/s, the headstages are actually
sampled at 200 kS/s to reduce noise, so this port produces a 200 kHz square wave during operation. The voltage level
of this signal is set by the CONFIG4 switch.
Mark out: This port generates digital pulses marking the onset and offset of voltage clamp or current clamp waveforms.
•
The voltage level of this signal is set by the CONFIG4 switch.
I/O GND: This binding post is connected to the controller system ground used by all analog and digital inputs and
•
outputs. This is the preferred ground to use for Faraday cage and other shielding connections.
Chassis GND: This binding post is connected to the controller chassis and to the grounding conductor of the AC power
•
socket.
Power switch and fuse holder: The unit uses two standard 1A 250V 5x20mm slow blow fuses that can be replaced
•
by opening the fuse holder to the right of the power switch. The power cord must be removed to access the fuses.
AC power socket: The controller is powered by 90-260V AC power, and is compatible with international voltage levels.
•
A US-style power cord is supplied with the controller. International customers must use an adapter to accommodate
non-US power sockets. The center grounding conductor must be connected to earth ground to avoid electric shock
hazards.
Mounting
The Intan CLAMP controller can be rack mounted on a standard 19" instrument rack using provided hardware, or it can be used
on a bench top by folding out the feet on the bottom of the case:
