I am working a project where I want to connect and control, using Labview,
- TDK-Lambda Power Supply
- Process Vacuum Controller Ion Gauge (MODBUS interface)
They both have rs232/rs485 capabilities, just depends on a switch on the back of the terminal and both connections are with a rj45 jack (I will attach relevant manual). And connect via a RJ45 cable, and I want to connect it to a computer.
Now, I've set up a .vi that should be able to connect to, or at least discover, the devices but to no avail. It might be because I am using a regular Cat5E Patch/Ethernet Cable and it therefore not the right pinout. I've tried to read some post and/or white papers about the subject, but these devices are specific and have different pinouts.
So my question is, how to I go about using an rj45 cable for serial communications? Can I simply connecting a cat5 cable to my laptops ethernet port and to one of the devices serial rj45 jack? Or am I missing something major?
This is my first attempt at anything like this, but I have used Labview to connect to serial DB9 to usb adapters and able to communicate.
I know I am asking for a lot of help here, but I am super lost and any help is much appreciated.
