I bought this wireless remote control from China that is used for a crane setup and I am planning using on a piece of equipment that has the same functions as a crane does (UP,Down,Left,Right,etc) Here is a link to the item lihttp://www.aliexpress.com/item/F21-12S-industrial-wireless-remote-control/1849738925.html After I got it I realized I needed a way to program the buttons to be momentary, lock on, etc. I was able to download the program to set all the parameters, so I am good on that. I just need to make a cable to connect to the 6 pin data port on the controller which looks like this
Here is what I found they sell in China, but they will only sell to companys that make these remotes. Its not for just anyone to buy. So I have to make my own.
I was able to get the place in chine I bought the remote from to send me a schematic of the USB writer and here is what they sent me.
I bought this USB to TTL thinking it would do what I needed but I didn't realize it was lacking the RTS signal. And I am sure there is more that I am missing. http://www.ebay.com/itm/FT232RL-USB-to-TTL-Not-Counterfeit-NEW-SHIP-FROM-USA-/261455019076?pt=LH_DefaultDomain_0&hash=item3cdfeefc44
I also have one of these left over from another project. USB to Serial RS232 with DB9 connector. I checked the pinout and I thought it may work, but there is no VCC/3.3 out put to connect to Pin 2 (one the schematic above the"WRI" connector) The IC's on this pcb are the FT232RL (which is the same one on the USB to TTL I bought) and the ZT213LEEA.
Looking at the schematic and a little research I did, it looks like the FT232RL is the same as the PL2303HX in the schematic but just a more reliable IC. The outputs from this FT IC go into the 74HC14D ( Data sheet http://exploringarduino.com/wp-content/uploads/2013/06/74HC14-datasheet.pdf ) and out to the writer port on the controller. I don't understand what this 74H ic does and if its needed. I read some info that it could be substituted with SOT-23 transistors. But the picture above of the cable they sell in China doesn't have this 74C14D. So I don't know what to make of it. That picture I found in a search and has no relation to the schematic I got from the company I got the remote controller from.
I also see in the schematic on the PL2303 pins 27 and 28 they have an OSC/Crystal? The data sheet ( http://www.prolific.com.tw/UserFiles/files/ds_pl2303HXD_v1_4_4.pdf ) says for pin 27 and 28 reserved pin and No Connection. So I don't quite get that either.
So what do I need to do to get this to work? I thought about using the USB to TTL board and cutting the trace from CTS and putting a jumper to the RTS and cutting the 5v trace and doing the same and connecting to the 3.3 instead. This would match the schematic pinout less the 74HC14D. I may be way off, but I just do not know enough about this stuff and how it communicates so I figured I needed to ask for help.
Sorry if my post is long and has useless info, I just like to give all the info I have when asking a question. I appreciate any info and direction/suggestions you have. Thanks
