DLP NIRscan Evaluation Module Overview
– Terminal 2 = NC
– Terminal 3 = NC
– Terminal 4 = UART_RX
– Terminal 5 = UART_TX
– Terminal 6 = NC
• J10 – Trigger In 1
– Terminals 1 and 2 = External connector triggers the DLPC350
– Terminals 2 and 3 = Sitara triggers the DLPC350 (default)
• J12 – Trigger In 2
– Terminals 1 and 2 = External connector triggers the DLPC350
– Terminals 2 and 3 = Sitara triggers the DLPC350 (default)
• J14 – Trigger out 1
– Terminals 1 and 2 = DLPC350 generated trigger out 1 (default)
– Terminals 2 and 3 = Sitara generated trigger out 1
• J16 – Trigger out 2
– Terminals 1 and 2 = DLPC350 generated trigger out 2 (default)
– Terminals 2 and 3 = Sitara generated trigger out 2
• J13 – Power selector for trigger out voltage levels
– Jumper installed = Trigger outputs on J15 use internal 3.3-VDC levels (default)
– Jumper open = Trigger outputs on J15 use voltage levels supplied J15 terminal-1
– Note: Externally supplied voltage levels need to be 1.8, 3.3, or 5 V
• J18 – DLPC350 hold bootloader
– Jumper open = Normal operation (default)
– Jump across this header to hold the DLPC350 in bootloader mode. This hold is required only if
the DLPC350 firmware becomes corrupted and requires reprogramming through the JTAG
boundary scan or USB (atypical).
• J19 – DLPC350 I
