RHS Stim SPI Interface Cables and Cable Adapters

RHS Stim SPI Interface Cables

The RHS stim/recording system uses a standard interface cable and connector scheme to transmit serial digital data and power over distances of several meters using the Serial Peripheral Interface (SPI) protocol.

The following RHS Stim SPI cables are available from Intan Technologies:

  • RHS 3-ft (0.9 m) Stim SPI cable (Part #M3203)
  • RHS 6-ft (1.8 m) Stim SPI cable (Part #M3206)

Multiple cables may be daisy chained to span lengths of several meters (see table below).

Intan RHS Stim SPI interface cable
RHS Stim SPI interface cables have self-aligning 16-pin polarized nano connectors on each end. The wiring pattern supports daisy-chaining multiple cables in series to span lengths of several meters.

RHS Stim SPI Cable Adapter Board

The RHS Stim SPI cable adapter board (Part #M4430) connects to a Stim SPI cable and brings out all 16 power and data wires to 0.1" pitch solder holes for easy access. This board may be used to interface RHS Stim SPI cables with prototype devices. It may also be used to connect RHS Stim SPI signals to a commutator, as described in the application note, Adapting RHS Stim SPI cables to a commutator (see below).

Technical details on the Stim SPI cables and connectors may be found in the RHS Stim SPI cable/connector specification (see below).
