Hi,
I've been asked to decode serial data passing between a point of sale system (fancy name for fancy cash register) and a gasoline fuel controller. Data typically consists of commands from the POS to the controller such as "what is your status", "you are auhorized to dispense fuel", "how...
Hi,
My company is pretty good at capturing RS-232 data between devices such as a point-of-sale system (cash register) and a serial printer, as long as we know the baud, parity, data bits, etc.
My boss thinks I can do the same thing with a USB connection and I'm telling him I cannot. He thinks...
Hi,
I needed to make a device to remotely detect whether or not a 120VAC circuit was live. We make a micro-based device that measures 0 to 5 VDC and converts it into a 10 bit number. Being in a rush and not wanting to screw around the best idea I could come up with was an open frame power...
My company makes a level sensing device that consists of a microcontroller board and a pressure transducer. The pressure transducer output ranges from 0.5 to 4.5VDC. The micro samples this line and sends the answer (10 bit number between 100 and 923) and from this and the density we figure out...
I just found this forum, and this is my first post. I am working on a fuel level sensor. The sensors are located in underground fuel tanks, and need to be connected to a panel inside the building. We have the sensor device ready and I need to specify how the wiring is to go from the tank to...
