miniLAB 1008 User's Guide Functional Details Digital I/O connector and pin out Digital I/O connections are made to the DB37 connector on the top edge of the miniLAB 1008. This connector provides connections for 24 digital lines (Port A0 to Port C7), six ground connections, and +5 V USB power out. Refer to Figure 3-2 and Table 3-2 for the DB37 connector pin out. Digital connections (Port A0 through Port C7) The 24 digital I/O pins (Port A0-A7, Port B0-B7 and Port C0-C7) are TTL-level compatible. Each pin has a 47 kilohm (kΩ) pull-up resistor and is configured as an input by default. If needed, the miniLAB 1008 can be factory configured to provide pull-down resistors. Caution! Port A0 through Port C7 have no overvoltage/short circuit protection. Do not exceed the voltage limits or you may damage the pin or the miniLAB 1008. To protect these pins, you should use a series resistor. 19 37 20 Figure 3-2. DB37 Digital I/O Connector Table 3-2.

Screw terminal wiring The miniLAB 1008 has two rows of screw terminals. Each row has 15 connections. Pin numbers are identified in Figure 3-3. The pins are labeled for eight-channel single-ended mode operations. 3-3 1
