I am writing a C++ program in Visual Studio to interact with URMC32 32 Channel USB Relay Module. I am able to successfully send seemingly every command except for relay writeall XXXXXXXX. I have seen posts on the web from other developers who experience this same problem (including in other languages), but I cannot find a solution! This command works fine via Hyper Terminal or PuTTY, but fails via WriteFile() in C++. From what I can see, a command cannot be sent which exceeds a certain character length (20?). What am I missing? (Firmware version: 00000006)
Hi Jonathan, This is a known issue that was present in older firmware versions. This is fixed in the later version (latest version as of today is V8). Please feel free to get in touch with us any time for free update to the latest firmware version. Thanks, Tom
