2) The S2 switch is factory set as shown below.
The OEN and OSS_SEL switch are set
HIGH
and will enable the DS90UB926Q outputs to toggle upon
power up.
3) The S3 and S4 switches are factory set as shown below.
All switches are set
HIGH
except 58 on S4. This sets IDx address to 58. Note only one switch is allowed
LOW
at a time.
4) The S5 switch is factory set as shown below.
All switches are set
HIGH
except 1. This sets MODE_SEL address to 1. Note only one switch is allowed
LOW
at a time.
5) On JP2, a 2-pin jumper is factory placed as shown below.
The jumper sets VDDIO to 3.3V. Note 3.3V does not need to be applied externally.

2.4. LVCMOS Output Connector Description
J10 – R[7:0], G[7:0], B[7:0], HS, VS, DE, PCLK
is the output connector for the DS90UB926Q data outputs.
These are the LVCMOS outputs of the DS90UB926Q, which are the odd numbered pins (left side pins on the
board). The even numbered pins (right side pins on the board) go to pin 2 (labeled “STRAP”) of JP12. The
factory configuration has a jumper resistor R145 that ties the even numbered pins (STRAP) to ground.
