4.3 Coding Solder Bridges
The board has four coding solder bridges to assign a permanent
state to the corresponding input bits of the microcontroller. The four
positions for coding solder bridges (ID 0 - 3) are each assigned to
one port of the microcontroller LPC2194/01 (
μ C). A bit is set (1) if the
corresponding solder field is open.
A concrete application is the identification of a PCAN-Router on the
CAN bus during a firmware upload, especially if several routers are
connected and in operation.
Do the following to activate the coding solder bridges:
Danger of short circuit! Take great care when soldering to
avoid short circuits.
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the card. Take precautions to avoid ESD.
1. Unscrew the housing on both sides.
2. For D-Sub version only:
Remove the screws next to one of the two D-Sub
connectors.
3. Pull out the board.
4. Solder the solder bridge(s) on the board according to the
desired setting.
Figure 3 on page 11 shows the positions of the solder fields
on the PCB. The tables below contain the possible settings.
5. Carefully put the board back into the housing.
6. For D-Sub version only:
Reinsert the two screws at the D-Sub connector.
7. Screw the two sides of the housing back together.
