I am using a null modem cable between an XD1230 and NEC E424. I have gone into my presentation settings and set the baud to 9,600 bps, stop bit 1, and ASCII protocol, per the manual for the E424. My XD1230 has firmware 4.8.114, autorun version 6.8.41, and I'm using BrightAuthor 22.214.171.124
The command string for power on is 01 30 41 30 41 30 43 02 43 32 30 33 44 36 30 30 30 31 03 73 0D this doesn't work when sending as "Serial bytes (comma separated)" as the D at the end is not allowed.
I tried sending it as "Serial String (EOL)" and "Serial String (no EOL)" I also tried those with the numbers in the command string as comma separated with no luck.
I then tried those broken up into pairs of 8 numbers e.g. "01 30 41 30 41 30 43 02" with multiple send commands, again with and without commas.
I tried using this converter: https://www.branah.com/ascii-converter to convert to decimal and use "Serial bytes (comma separated)" The output of the converter gives groups of 4 numbers, which BrightAuthor won't take. So I broke them up into groups of 2 number e.g. "48,49,51,48,52,49,51,48" as well as the entire string at once.
I even tried BrightControl "Send Ascii string" although I think that is for CEC commands.
All of this was done over Port 0. The NEC manual doesn't specify a port. Is there some way, from what appears to be limited information in the manual, to convert these ascii command strings into a format that works from BrightAuthor or a certain way I'm supposed to send them? Will the XD1230 even be able to turn this screen on, since it wants these ascii strings?
My test presentation is setup with a series of images, with the entry command for each image set with the different permutations listed above, to turn the screen on, then display the image for 15 seconds. My thinking is that whatever image shows on the screen when it's on contains the correct setup. None of the above works though. If anyone has a sample presentation that works with this particular model, that would be great! I've attached the NEC code reference for this model of screen.
