Using a GPIB USB HS converter to control a turn table (Sunol system controller Model SC99V)

[Leaf]

This is my first time trying to control devices over GPIB, so it may be a simple solution. 

For context, I am trying to use a GPIB USB HS converter to remotely control a turn table. The goal would be to have a button that when pressed, a section of code would scan the current angle of the turn table, and depending on if its greater than 350 degrees or lower than 10 degrees, it would rotate the table in the opposite direction (So one press of the button would guarantee a 360 degree rotation). The turn table has a list of valid GPIB commands, which I will link. It also has some relevant information in other parts, so I have linked them as well. (see the 3 docs labeled turntable operations manual)

Where I am getting stuck is trying to send these codes to the device from my computer. I have tried GPID interactive control, NI-488.2 Communicator, and the VISA Test Panel. I wanted to do a simple proof of concept, and just move the turn table to 100 degrees. This would be the command "CP 100". The command "CP" should return the current angle, which I was also trying to use. I attached photos of the results. I had tried many different types of syntax to match the examples under the operations manual in the interactive control, but I could still have this wrong. (see photos named Command) In the VISA interactive control, Im getting more progress. When I input "CP 100" then press write, it converts it to "CP/s100". The turn table did not move though. So I tried "CP" and clicking read, which gave me a time out error. (see photo named VISA). Next I tried the NI-488.2 communicator, which seemed to be similar to to the VISA. (see photo named NI488.2) 

Without getting any progress, I tried the NI I/O trace capturer. I Tried to get a decent photo, but let me know if there's better information in this tool. (image NI I/O cap)

My question to the group is do you see anything I am obviously doing wrong? This is my first time working with GPIB commands, so any advice would be apricated. I did my best to include as many details, but if theres more information you'd want to see please let me know. Thank you for your expertise.
