A.3.3 Jumpers

connectors

The jumpers and connectors numbered below refer to the CPU board schematics (available
from your local ST representative).

Sheet 4

●

Connector J3 is a standard 20-pin 2.54 mm connector used for JTAG connections.

●

Jumper J5 enables the power supply to the Real Time Clock block.

If jumper J5 is closed, the RTC is powered (standard).

●

Connector J10 is a 2 vie 1.25 mm pitch connector for battery back-up with cable.

Sheet 5

●

Connector J11 is a standard power connector for the ADC power supply with a 2.1-mm
central pitch.

Sheet 6

●

Jumpers J6, J7, J8 and J9 are serial jumpers for the SPEAr power rail.

All jumpers MUST be closed. This configuration is used for power measurements.

Sheet 7

●

Jumper J22 is a 4-pin symmetric IDC (or strip) connector that switches RX and TX
signals for different types of RS-232 cables

(a)

–

Two pins are connected to the ST3232 Receive/Transmit side.

–

Two pins are connected to the RS-232 Receive/Transmit connector side.

●

Connector J17 is a connector for standard IDC-to-DSUB converters.

●

Jumper J20 switches between RS-232 transmit signals or GPIO2:

–

If jumper is on pins 1 and 2, pin PL_GPIO2 is connected to U12 (ST3232) and the
COM0 is available on J17.

–

If jumper is on pins 2 and 3, pin PL_GPIO2 is connected to the expansion
connector J12 pin 9. In this case

the COM0 is available on CN13.

●

Jumper J21 switches between RS-232 receive signals or GPIO3:

–

If jumper is on pins 1 and 2, pin PL_GPIO3 is connected to U12 (ST3232) and the
COM0 is available on J17.

–

If jumper is on pins 2 and 3, pin PL_GPIO3 is connected to the expansion
connector J12 pin 11. In this case the COM0 is available on CN13.

a. With 2 jumpers (inserted) the user can switch between two cases; two jumper inserted "vertically" or two

jumpers inserted "horizontally". This enables the user to adapt the serial cable (null modem cable) to the CPU
board. See
