Page 3: Introduction
Introduction The FM-1600 Fiber Optic Multiplexer is in essence a two-pole, eight position fiber optic switch. It is intended to be used in FTIR spectroscopic applications to select any one of eight optical sampling regions and interpose it in the interferometer optical path. Switching both ends of the optical path eliminates the spurious spectral distribution problems encountered when using fiber optic bundle source distribution to sampling regions. -

Input Power Requirements The FM-1600 is equipped with a universal power supply. It may be operated from any line voltage between 95 and 260 V.A.C. , 50-60 Hz. It is not necessary to change any settings on the instrument to cover this voltage range. -
Page 6: Controls & Their Functions
FM-1600 Front Panel Controls & Their Functions The front panel controls are illustrated above. There are three parameters that may be set. These include the channel that is in use, the device address that is to be used for serial communications, and the baud rate that is to be used for serial communications. -
Page 7: Serial Commands
Serial Interface The FM-1600 is equipped with a “three-wire” full duplex Rs-232c interface. It permits the unit to be remotely controlled via an external controller and will report the unit’s status on request. The unit may be equipped with an Rs-422 or Rs-485 adapter to interface with other systems. -
Page 8: Operational Considerations
To set a unit whose front panel address is set to 15 to channel 07 with Local Lockout send the following string: m;15071CR To request a status report from the unit send the following string: m;15staCR The unit will transmit back its address, current channel setting, Local Lockout condition and baud rate . -
Page 9: Theory Of Operation
Theory of Operation The FM-1600 moves the two armature fibers that are physically connected together. They stop pre- cisely in front of fibers 0 through 7. The microprocessor receives position and command data from the keyboard controls as well as the Rs-232 port. The appropriate information is displayed on the unit’s LED display or sent out over the Rs-232 port. -
