8. YAV modules overview
The use of YAV modules provides a real technical, economical and logistic advantage against
all other classic instrumentation solutions. YAV modules are the solution for typical practical
problems that occur while designing test platforms. They provide a considerably test system
performance increase. The minimal amount of connections and wiring length reduction main-
tains the best quality and integrity of the signals and provides a short assembly and wiring time.
Being a combination of hardware modules and software drivers, the implementation of the YAV
modules in your test system is very fast. When connected, the modules are immediately
operative. YAV modules make your test system very flexible, re-configurable, easy to expand
and maintain. Each modules can work independently form the tester so you can just plug each
of them directly into the ITA frame of a fixture to start debugging the software without the need
of using the test platform. While the tester is being used to test PCBAs you have the advantage
to debug or build any new configuration in a few minutes.
Can bus control has a big advantage; it provides all the control and power supply signals to
power the YAV modules with just 4 wires. Therefore the modules can be mounted in any part of
the test system or test fixture. The Can bus transmission speed might be lower than the one
available in parallel buses, but it is at least 100 times faster than the speed needed to control all
the available functions in each of our YAV modules.
8.1 YAV modules common information
8.1.1 SW1 DIP switch functionality
The eight switches contained in SW1 are covering the following functionalities:
Set CAN bus speed
Set module address
ON
1 2 3 4 5 6 7 8
ON=1
OFF=0
8.1.2 CAN bus communication speed.
Switches 1 and 2 set the CAN communication speed:
Select 50Kb/s to communicate with Phi6 and all 6TL modules. All devices communicating
through the CAN network must have the same speed configured in order to communicate
properly.
