CHAPTER 6 Optional Interface Boards
Initial Setting
Be sure to turn OFF the power of the LS controller, then set these switches.
Since the GP-IB allows up to 15 devices to be interconnected, an address
must be assigned to each device. To assign the address, use the DIP
switches on the back panel of the LS controller. (See the figure below). The
talk only mode or delimiter can also be set using these switches.
