The SX199 Optical Interface Controller is a communications bridge to connect up to any four analog lock-in amplifiers (SR124 or SR2124), current sources (CS580), or DC voltage sources (DC205) with a serial optical interface to a computer's' remote interface via GPIB, Ethernet, or RS-232.
The front panel of the SX199 provides simple monitoring of the status of the remote interface and optical port connections. There are three LED sections available for Power, Ports, and Interface activities.
The rear panel of the SX199 provides all external interface connections and the power switch. The optical ports are in the upper block of the rear panel. Remote connection to the SX199 is supported with GPIB, RS-232 and Ethernet computer interfaces. These interfaces can be configured by the rear-panel DIP switches.
