General Information

D188 Intended Usage & Description

The D188 Remote Electrode Selector can be used to direct electrical stimuli from a single stimulator to

one of up to eight pairs of stimulation electrodes. It is particularly useful in applications where a stimulus

needs to be presented to several stimulation sites, one site at a time, but only one stimulator is available.

Channel selection is controlled by TTL compatible digital inputs applied to the rear panel socket on the

D188 or manually via Windows compatible software (supplied). A pair of stimulus inputs is provided for

connection to a compatible electrical stimulator and there are eight pairs of stimulus outputs (channels),

numbered from 1 to 8, each associated with a green LED to show when they are active. These LED's can

be turned off for situations where it is important that the subject does not know which channel is active.

Although the D188 has been designed with human applications in mind, the D188 is not a medical device,

so its use is limited to research applications. It should not be used for patient treatment or diagnostic

purposes.
