Chapter 2 Jumper Description

This chapter shows the jumpers layout and explains how to setup the jumpers.

Jumper Layout and Configuration

Figure below, shows the jumper layout of the SpacePC 1232 module.

In the below figure, the jumpers are indicated as JP followed by the jumper's number, while pin 1

of every jumper is indicated by a red square pad.

Figure 2. Jumpers and solder jumpers on the SpacePC 1232 module

12

The following jumpers are located on the module:

One 3-pin jumper (JP5) for which there are only two possibilities:

¾ Connecting pin 1 to pin 2 (which will be indicated as 1-2)

¾ Connecting pin 2 to pin 3 (which will be indicated as 2-3)

Three 2-pin jumpers (JP1, JP7, JP8), which can be set as follows:

¾ Pin 1 connected to pin 2 (which will be indicated as ‘Closed’)

¾ Pin 1 and pin 2 not connected (which will be indicated as ‘Open’)

The following table provides a quick cross-reference for the SpacePC 1232 module’s jumpers.

J1 and J2 for the ISA Bus

The ISA BUS

Connectors J1 and J2 carry the signals for the ISA Bus. These signals match definitions of the

IEEE P996 standard. Below is shown a picture of the ISA BUS

Figure 4. ISA BUS layout

According to PC/104 specifications, KEYs are filled holes in the upper side and missing pins in

the lower side of the bus connector. This is made to avoid the wrong insertion in/of another

module.

For further info about ISA (PC/104) bus, please refer to the PC/104 Consortium Web

site at www.pc104.org

.

How to connect to the CPU other PC/104 & PC/104 devices: the stack

assembly

The ISA Bus connectors of the module are designed to allow the connection onto a stack of other

PC/104 and/or PC/104Plus devices. We recommend you to follow the procedure below ensuring

that stacking of the modules does not damage connectors or electronics parts.

1. Turn off power to the PC/104 system or stack.

2. Select and install standoffs to properly position the module on the PC/104 stack.

3. Touch a grounded metal part of the rack to discharge any accumulation of static electricity.

4. Remove the module from its anti-static bag.

5. Check that keying pins in the bus connector are properly positioned.

6. Check the stacking order; make sure an XT bus card will not be placed between two AT bus

cards or it will interrupt the AT bus signals.

7. Hold the module by its edges and orient it so that the bus connector pins line up with the

matching connector on the stack.

16

8. Press evenly the module onto the PC/104 stack.

The picture below shows a typical module stack with 2 PC/104 modules, 1 PC/104 16-BIT

module, and 1 PC/104 8-BIT module.

The maximum configuration for the PCI bus of PC/104 modules is 4 plus the Host Board.

If standard PC/104 modules are used in the stack, they must be the top module(s) because they

will normally not include the PCI bus.

Figure 5. The Module Stack

Do not force the module onto the stack! Wiggling the module or applying too much

pressure may damage it. If the module does not readily press into place, remove it,

check for bent pins or out-of-place keying pins, and try again.

J3 for Multifunction & J14 for Mouse

J3 is a double row 5 x 2 pin with 2.54-mm step connector and allows the connection of a speaker,

a keyboard, and a battery to the SpacePC 1232 module.

J14 is a 4 pin with 2-mm step connector and allows the connection of a PS/2 compatible mouse.

Later on there is a brief description about the Parvus Multifunction Adapter and the VGA and the

Ethernet.

 System reset

Connecting the pin 3 of the multifunction connector to ground performs a hardware reset

of the module. It is possible to use an external push-button, normally open. J3 provides a

connection for an external normally-open pushbutton to manually reset the system.

Connect the other side of the switch to ground. The reset signal is “de-bounced” on the

board.

 External Battery

Pin 9 of the multifunction connector allows the connection of an external backup battery

(typically from 3 to 3.9 V). This battery is used at power down to preserve the date-time in

the Real Time Clock.

The typical battery consumption with the module off is 7 uA.

 Speaker

A transistor to supply 0.1 watt of power to an external speaker controls these outputs. A

transistor amplifier buffers the speaker signal. Use a small general purpose 2 or 3-inch

permanent magnet speaker with an 8-ohm voice coil.

19

The audio output is based on two signals: one come from the output of Timer 2, and the

other come from I/O port 61h compliant with the AT Standard.

 Power button

If the soft power management is enabled, a low signal in the pin10 turns the system on or

off.

J14 Mouse Connector

A PS/2 compatible mouse can be connected to the J14 connector (4pins, 2-mm step).
