Based on the original CJ Slip Ring Adapter Boards from 2007.

• Two matching adapter boards with high-density 26 pin D-SUB connectors
• Two power buses, V1 & V2, or can be combined (jumper) into one bus for higher amperage/current. This is the default option
• 16 Amps max on the combined V1/V2 bus (15 of the lines of slip ring are dedicated to power)
• 5 Servo Connectors / pass thru (Data Only, No power)
• i2c Bus pass thru (SCL/SDA,GND - not V)
• Serial (RX,TX, GND) pass thru (common ground)
• Servo Connectors can be repurposed for any data lines, e.g. extra serial or i2c
• Second V2 header terminal block can be used for local low amperage secondary device.
• 5V terminal block for servo power input - INPUT ONLY, does not pass thru slip ring - unless you route 5VDC power thru V2 bus.
• Extra holes for wire strain relief / zip ties.
• Small/Compact

* Requires 24 wire Slip Ring (not included. Search Google/eBay for KYC24A)

DSUB Pin Allocation:

Pins 1-9 are data
Pins 10-18 all connected to Ground
Pins 19-26 all connected to Power (typically +24/12VDC)

On a 24 wire slip ring connect them as follows:

9 wires to DSUB pins 1-9 (Data)
7 wires to DSUB pins 10-16 (Ground)
8 wires to DSUB pins 19-26 (Power - Typically +24/12VDC)

If you do not need all the data lines you can use the extra/spare wires for power.
