ZHCSA85F August 2012 – February 2019 DLPC410
The DLPC410 will only initialize the second DLPA200 (number 2) when it detects a DLP9500 or DLP9500UV DMD is connected. The DLPC410 output DAD_B_SCPEN (pin AB19) signal will assert indicating that the DLPC410 is ready to communicate with DLPA200 number 2. Signaling should be seen on SCPCLK (pin AB15), SCPDO (pin AA15 - SCP output from the DLPC410) and SCPDI (pin AA15 - SCP input to the DLPC410) traces. Be sure that the direction of the SCP input and output signals are connected correctly.
When DLPA200 Number 2 initialization is complete, check VBIAS, VRESET, and VOFFSET voltage values on the DLPA200 number 2 and compare against the DLPA200 data sheet specifications for the DLP9500 or DLP9500UV DMD.
