The MTA-100 connectors provide a simple way to create custom interconnect cables without need for expensive tooling.
All Clockworks products use a standard connector arrangement to carry power, control, and status. Details of the pinout can be found in the SignalBlox System Configuration guide. The 8 pin connector carries the analog +/-15V and +/-5V supplies, along with the on/off control.
The 12 pin connector carries 3.3V standby, and primary 3.3 and 5V supplies, along with on/off control (for the primary 3.3 and 5) and power fail status.
Carrier boards also have a 6 pin MTA-156 connector for user defined power, a cable for that is not included in the set.
