OEM connector
The OEM connector operates in parallel with the USB connector — do not connect to both the USB connector
and the OEM connector.
The OEM connector is a 0.1" box header. Pins 2, 4, 6, 8, and 10 provide a USB connection, as listed in the
connector pinout below:

Modifications are required in order to use the OEM connector
We recommend that you return the device to the factory for this modification.
Should you have the capabilities to perform the modifications, the following change is required: in order to
create a USB connection via the OEM connector, locations R48 and R49 must be populated. We recommend
that you populate with 0603 size 0 Ω resistors or provide solder bridges to close the gaps.
Trigger/Sync connector
The Trigger/Sync connector provides two signals —
the screw terminal (see page 15 for details about these signals).
Use a 0.1" box header when making connections to the Trigger/Sync connector.
The Trigger/Sync connector internally connects its SYNC and TRIG_IN pins to the screw terminal via jumpers
and

Sync jumper (P6)
The Sync jumper internally connects the SYNC pin on the Trigger/Sync connector to the SYNC pin on the
screw terminal. Remove this jumper on boards that will not send/receive the SYNC signal through the
SYNC/TRIG connector. Refer to Figure 2 on page 10 for the location of this jumper.
