We would expect that you should be able to type the command directly in HyperTerminal, or create a simple *.txt file with the three commands and send it to the sensor. However, if the sensor is already sending all the navigation data, you might have trouble find the response.
We have contacted the manufacturer to ask them help in more detail with getting their software to work properly for you. Unfortunately we are not very familiar with the StarGazer Monitor, so this problem is exceeding the first level support that RobotShop usually provides. We will let you know when we get a response.
The Hagisonic has a serial output - you need a serial to USB adapter. The adapter you linked to is for Dynamixel (brand) servo motors. The output looks like a VGA connector, but in fact it’s DB9 (two rows instead of three).
"Please make sure if the customer’s StarGazer works fine with usb-to-serial cable. If not, please guide the customer to send the StarGazer to us. (Invoice indicating ‘Sample’). We don’t have experience in UartSBee and droid. So, if possible, please guide the customer to send us the whole above items as well. We will test it and fix it if it is needed. Thanks.

RB-See-105 is in stock in our main North American warehouse but not on the European one. If you order it from Europe, there will be a delay of around a week.
It does not matter which end of the cable you plug in first. What matters is that you only plug the proper hardware to your computer with secure connections in order to prevent possible issues.
