Inline Switch Driver (TTL/CMOS compatible)
Quick and Easy Testing and Prototyping
This switch driver allows our switches to be easily controlled using a common TTL
or CMOS output for testing or prototyping. The electronics for the control are built
inline as part of the 1 meter ribbon cable. One end of the cable is equipped with
an IDC connector, ready to be connected to our optical switches. At the other
end, a bare ribbon leaves the connectorization up to the user.
Full schematics are available from the download section below
for both the latching and non-latching versions of the driver board. These
schematics also serve as example circuits for controlling
Luminos optical switches with TTL outputs.
Note: this driver is not compatible with a "center off" switch.
