The SW-DR-2 evaluation kit is comprised of a driver board, a switching mounting board, software, a power supply, and a computer interface cable. It is designed to drive and control Photonwares CrystaLatch™ (CL), LightBend™ (LB), Fiber-Fiber™ , and MEMS optical switches up to 15 switching points. The switch driving board integrates both standard USB and TTL interfaces, allowing the user to easily create flexible and customized control logic configurations. It features real-time control and supports all port configurations of Photonwares CL and LB series switches. A user-friendly GUI Windows™ program is included for switching testing.  A RS232 interface also includes that require jumping.  We also provide Labview control software.

The standard driver controls one individual switch. Drivers that control multiple switches also are available, please contact sales.
