Having issues with IP Bus Strobe (J19) on Motorola MVME162P4 VME Embedded Controller? Read our step-by-step SMT maintenance solution below. If you require replacement feeders, nozzles, or sensors, contact SMTBOX for OEM-compatible parts.
Some IP bus implementations make use of the Strobe? signal (pin AA19 on the Petra ASIC) as an input to the IP modules from the Petra IP2 sector.
Other IP interfaces require that the strobe be disconnected.
With a jumper installed between J19 pins 1-2, a programmable frequency source is connected to the Strobe? signal on the IP bus (for details, refer to the Petra/IP2 chip programming model in the Programmer’s Reference Guide).
If the jumper is removed from J19, the strobe line is available for a sideband type of messaging between IP modules. The Strobe? signal is not connected to any active devices on the board, but it may be connected to a pull-up resistor.
