DLP NIRscan Evaluation Module Overview
Table 1-3. DLP NIRscan Connections
Connection Type Description
1 DLPC350 I
2
C bus Do not use while the Sitara processor is controlling the DLPC350.
2 Fan power Power output from the spectro board to power the fan.
3 TEC control cable
Connects the TEC driver board to the detector board to drive the detector TEC and read
the thermistor value from the detector.
4 Micro-SD card slot Used for future DLP NIRscan software upgrades.
5 USB connectors
There are two USB expansion connections in connector 5. These connections can be
used for most USB-compatible applications, such as USB memory storage, USB WLAN,
or Bluetooth applications. The software to support these expansion features is not
included in the DLP NIRscan EVM.
6
Mini-USB interface to
the DLPC350 USB connection allows the DLP LightCrafter4500 GUI to access the DLPC350 or to
control the DLPC350 through an external USB-capable microcontroller.
7 Ethernet RJ45
Alternative to the Ethernet-over-USB connection 14. As of software release v1.0, to use
the ethernet connection requires knowledge of the IP address assigned to the DLP
NIRscan EVM at power-up. If a static IP address cannot be assigned, TI recommends
using connection 14.
8 Power connector
Use a power supply with a 12-V DC output with 3- to 5-A current rating and a plug of
2.5-mm inner diameter × 5.5-mm outer diameter and 9.5-mm female center positive shaft.
9 Lamp power Connector from the lamp driver board to the tungsten-halogen lamp.
10
JTAG interface for the
DLPC350
11
External trigger input
connector
Supports two trigger input signals for DMD pattern synchronization.
12
External trigger output
connector
Supports two trigger output signals. These are jumper configurable:
• With jumper J13 installed, the output triggers are referenced to internal 3.3 V with up
to 100 mA available at the external connector.
• Without J13 installed, the triggers are reference to an externally supplied
1.8- to 5-V input.
13 ADC converter SPI bus Data interface to the ADS1255 ADC
14 Mini-USB to Sitara
Main method of connecting a laptop, desktop, or PC to the DLP NIRscan EVM. The
supported protocol is ethernet-over-USB and requires the RNDIS driver on the host PC.
15 S1 Resets the DLP NIRscan to its power-up condition.
