Prototype of Power Supply Control of Transport Lines in BEPCⅡ

In order to effectively utilize the existing CAMAC devices in BEPCⅡ and realize the remote control of the magnet power supplies in the transport lines, VME modules are used as CAMAC serial driver, which can be connected with CAMAC crates to compose serial highway, and control CAMAC I/O modules via a CAMAC crate controller. The paper describes the procedure including development of CAMAC I/O modules and the application software. This prototype system solves some important problems on the construction of PEPCⅡ.
