Description

DESCRIPTION

Stimulate different sites with 1ms switching times
The D188 Remote Electrode Selector allows you to direct an electrical stimulus of up to 1A (at 400V) from a single stimulator to one of up to eight pairs of electrodes. The D188 is supplied with “virtual front panel” software compatible with WindowsTM 7 and higher, which permits manual switching between stimulation sites via a key-press or mouse click. However, the D188 was predominantly designed for situations where stimulation delivery needs to be rapidly switched between sites under remote, digital control.  With switching times of 1ms, the D188 Electrode Selector can be used for demanding stimulation applications involving multi-location stimulation in studies of pain, cognitive behaviour or sensory perception.  An example of a typical stimulation system incorporating the D188 is given in the diagram below.

Multiple control methods
Precisely timed remote control is possible through the use of TTL compatible digital lines from your data acquisition system. One to one control requires eight digital inputs, however, the D188 Remote Electrode Selector can also operate in a multiplexed mode where only four digital inputs are required. Alternatively, a USB connection to the host computer allows software control of the D188 via a DLL-based API, which can be accessed using your preferred software (C, C++, Visual Basic, C# etc). The D188 is recognized and controllable as a serial device within LINUX operating systems, although our virtual front panel software is not LINUX compatible.

Designed for human research applications

The D188 is silent in operation and the software control panel allows the operator to toggle the LED indicator lights on and off. As a result, the subject of stimulation is not provided with any audible or visual cues of stimulus delivery. The D188 Electrode Selector is not a medical device and use is restricted to human research applications, however, it has been designed to meet certain aspects of IEC 60601-1 relating to safety.

The D188 Remote Electrode Selector not supplied with any stimulator input or electrode connection cables, however, it is possible to purchase additional plugs and cables to suit your requirements.  These either allow direct connection of the D188 to our complete range of isolated stimulators. We also offer output extension cables for the D188 in order to increase the distance between the stimulating electrode and the D188 output sockets.

Multiple Stimulator Connection Options

Recommended Connection via D185-HB4 Output Adaptor Cable
For direct connection to a D185-HB4 Output Extension Cable, the D188-09 (200cm) or D188-10 (50cm) 1.5mm cables can be connected between the D188 Electrode Selector and the D185-HB4.

Direct Connection to Digitimer DS5, DS7A/AH or DS8R Stimulator Outputs (4mm)
For direct connection to the stimulator 4mm output sockets, we offer the 50cm long D188-12.

Direct Connection to Digitimer DS2A, DS3 or DS4 Stimulator Outputs (2mm)
For direct connection to the stimulator 2mm output sockets, we offer the 50cm long D188-11.

Electrode Connection Extension Cables

In situations where the electrode lead length is not adequate to connect between the subject and the front panel of the D188, we offer pairs of D188-13 (100cm) or D188-14 (200cm) Output Extension Cables.  These cables are fitted with male and female 1.5mm DIN 42802 connectors at each end and are supplied in red and black pairs with sleeving placed at regular intervals to prevent tangling.
