Appendix B: Connector Pinouts

QCard connectors
PowerDock connectors

The QCard Controller Starter Kit comprises a stack of two boards: the PowerDock Board, and the smaller QCard Single Board Computer (SBC) based on the 68HC11 microcontroller. Pin-outs for all input-output (IO) connectors on the QCard Board and the PowerDock Board are provided here.

QCard connectors

The pinouts of all of the connectors on the QCard Board are presented below. To locate the connectors on the board, consult Figure B–1 and the white silk–screened labels on the visible side of the QCard Board. The arrows in the figure point to the locations of pin 1 on each connector.

QCard Connectors and Switches. Arrows locate pin 1 of each header.

For more complete information about the QCard headers listed on this page, please see Getting to Know Your QCard Controller. Other pages in this QCard Controller Users Guide provide information on how to code C-language instrument control applications using the board.

H1: Power Header

Pin	Signal
1 –	V+RAW (+8 to +26 VDC)
2 –	GND
3 –	+5 VDC
4 –	TDI for JTAG programming
5 –	TMS for JTAG programming
6 –	TCK for JTAG programming
7 –	TDO for JTAG programming
Note: V+RAW is needed only if certain WildCards are used. Pins 4-7 are generally not used.

AN3/PE3	– 21	22 –	PE2/AN2
AN1/PE1	– 23	24 –	PE0/AN0
Note: Signals in parentheses indicate options configured by installing appropriate zero ohm shorts on the board.

H3: Wildcard Port Header

Signal	Pins		Signal
GND	– 1	2 –	+5V
/IRQ	– 3	4 –	V+Raw

H4: Communications Header

Signal	Pins		Signal
/TxD1	– 1	2 –	/RxD1

RS485 XCVR-	– 5	6 –	RS485 XCVR+
/TxD2	– 7	8 –	/RxD2
DGND	– 9	10 –	+VBAT
Note: This pinout matches that of the Docking Panel comm socket, but differs from the comm header (right-angle pins) on the Docking panel. On the docking panel comm header, pin 4 is connected to DGND and pin 10 is connected to +5V.

PowerDock connectors

The pin-outs of all of the connectors on the PowerDock are presented below. To locate the connectors on the board, consult Figure B-2 and the white silk–screened labels on the PowerDock.

Headers on the PowerDock. The small numeral 1 locates pin 1 on each header.

Serial Connectors, Power Jack, and Power Switch on the Back of the PowerDock.

H1: Serial Communications Connector

Signal	Pins		Signal
/TxD1	– 1	2 –	/RxD1

RS485 XCVR-	– 5	6 –	RS485 XCVR+
/TxD2	– 7	8 –	/RxD2
GND	– 9	10 –	+5V
Note: This pinout differs from that of the QCard pinout: on the QCard pin 4 is connected to /MOD1.CS and pin 10 is connected to VBAT.
