The MDC-300 communication cable can be used to connect a spectrometer directly to both a computer and a power source. Note that some cables (labelled MDC-300) are equipped with an under- and overvoltage protection circuit. This circuit protects the hardware against voltages which are too high (up to 60V) and against reverse polarity issues. The MDC-301 cable does not have any voltage protection. Aside from the label, the MDC-300 and MDC-301 cables have identical appearance.
Includes electronics which protect the spectrometer against voltages which are too low (including negative voltages caused by reversed polarity) and voltages which are too high.
|MDC-301||Does not include any voltage protection.|
The connection scheme for the MDC-300 cable is shown below. The MDC-301 cable has the same connection scheme, but is lacking the voltage protection circuit. The voltage protection circuit in the cable prevents the power lines from being inspected using a multimeter.
Note: Pin numbering as seen from the solder side.
