M9B-HFS INTERFACE FEATURES
Release 1.0 (97/10) 1-1
1. FEATURES
1.1 Introduction to the Interface
The M9B-HFS Interface is a microprocessor-controlled option card for the 1200 Watt or 2800 Watt model power
supply. Installed internally, the M9B-HFS gives you remote digital control of simple test systems. It has 16-bit
resolution for programming and readback and uses bit serial protocol for sending data between the computer and
the interface. The fiber optic link provides electrical isolation between the host computer and the power supply.
Electrical isolation reduces the impact of noise on communications to the power supply and improves signal
quality.
The M9B-HFS features an extensive command set and several user-programmable features. In addition to fiber
optic cable and a computer interface, this remote control application requires a computer-based communications
software package such as PROCOMM, XTALK, Windows Terminal Program or equivalent communications
software. You can also use low level or high level language programs to control your system. The M9B-HFS is
an ideal tool for reliable, remote power supply control of research and development applications.
