Batch Script to turn on/off via serial com port epson projector EB982W
Hi Everyone! I have been working on a script to turn on or off a epson projector EB982W, with no luck. They say in there documentation that they support esc/VP21 commands and the command to power on/off are PWR ON or PWR OFF. more info can be found at this link: https://files.support.epson.com/pdf/pltw1_/pltw1_cm.pdf I found a blog on stackoverflow: https://stackoverflow.com/questions/29259471/how-can-i-turn-my-projector-off-using-command-prompt-or-powershell that specifies how to open a port and send commands with powershell as so: $port = new-Object System.IO.Ports.SerialPort COM4,19200,None,8,one $port.open() $port.WriteLine("<command>") I have also tried $port.Write("<command>") the port opens successfully but the commands are not received by the projector. I would like to note that I have successfully sent commands with mobaxterm, proving that there is no hardware problem etc. Does anyone have any experience with this, direction, solution or advice. I have already taken advice from numerous people without any success
Reading data from a scale via serial port
Hello all I am trying to find some way to write data coming from a scale, device that reads weights, into a data field for an already created form. The scale would be connected to a computer via a serial port. User open up the form with fields filled in by the user, the form references a unique id (that was inserted by the user), that unique id is used to pull the correct weight data from the scale and populate onto the form. I have read that I need to create an application via VBA using MSCom but I dont see them connecting VBA application with Access form. Any help would be appreciated.
