Multiconnector M3

A passive interconnect board (type 3 / M3) that sits between the main XPOW/XDAC system and a device under test. It consists of 40 channel outputs suitable for applications using banana connectors, breaking out to 4 mm banana female sockets as well as 2.54 mm pin headers, with dedicated CONF reconfiguration pins and per-channel/GND checkpoints, so the same board can be wired to suit different DUT connector types without modifying the main system.

Key Features

●     40 channels broken out to 4 mm banana female sockets (point A, X1–X40)

●     Dual output options per channel: banana socket (point A) or 2.54 mm pin header (points B and C)

●     Dedicated CONF reconfiguration pin headers (points D and E) to remap channel/GND assignments

●     Ground checkpoints (2 pins, points I/J) and per-channel output checkpoints (point H, 1–40) for multimeter verification without disconnecting cabling

●     Direct pass-through connectors (points K/L) to the main XPOW/XDAC system — factory pre-wired

●     Compact, passive PCB — no external power required beyond what passes through from the main system

●     Supports both banana-connector and pin-header DUT connections from a single board

Callouts A–L correspond to the physical points on the M3 board used to configure connections to the DUT. Point A is the DUT-facing banana socket; points B and C mirror the X and Y channel outputs in pin-header form; points D and E are the CONF reconfiguration pins; points F and G carry the GND/channel mapping; point H is the channel checkpoint; points I and J are the GND checkpoints; points K and L connect to the main system.

Wiring Logic

●     Callout B (X1–X40 pin header) is wired to callout D (CONF X1–X40); callout C (Y1–Y40 pin header) is wired to callout E (CONF Y1–Y40), following the same X/Y grouping used across the multi-connector family.

●     Points K and L connect to the main system and are pre-wired at the factory (GND and corresponding channel outputs already mapped).

●     Points F and G directly correspond to points K and L, where the top row is GND and the bottom row (C1–C40) is channel outputs.

Example 1 — Banana-input DUT

For a DUT with banana-plug inputs (e.g. 2 channels), connect directly to any available banana socket on the board (CH1–CH40), since the banana sockets at point A are already wired through to the main system via points K/L. Select the matching channel (CH1–CH40) in the control GUI.

Example 2 — Pin-header DUT

For a DUT with an 8-channel 2.54 mm pin-header input, in factory-default configuration, channels 1–8 can be wired directly from point B or C. Outputs are available at X1–X40 (point B) or Y1–Y40 (point C); GND is provided via the corresponding CONF/checkpoint pins.
