Tyskern Posted March 27, 2017 Report Posted March 27, 2017 Hi. I'm having some trouble with controlling my projector with serial commands. I have a setup with a new pc with an ATEN UC232-A usb->rs232 converter. its set up as COM1. COM baudrate is set to 38400. Projector is a NEC px7000w, baud rate of the same. On production computer I made a string output , serial port, right baudrate. the NEC manual wants me to send this string 02H 00H 00H 00H 00H 02H (for power on) I guess thats $02$00$00$00$00$02 as the 'data to send'.. Now I've tried different syntaxes, adding carriage return on end etc.. But I get zero response. If anyone has any ideas as to what I'm missing I'd be very grateful. It might be simple, I dont have too much experience with serial stuff. T 0 Quote

Dataton Partner RBeddig Posted April 28, 2017 Dataton Partner Report Posted April 28, 2017 Whenever you run into such problems, the best way is to use a Telnet client on the same computer to send out the string. This usually also shows you possible answers from the controlled device. If it then works with a Telnet software you can try to port the result to WATCHOUT. Always add $0D at the end. 0 Quote
