Optical Systems Design 139AF Modem Asynchronous Fibre Optic Multi Mode RS232 - Transmitter and Receiver

Modem Asynchronous Fibre Optic Multi Mode RS232 with 25 pin Female D-subminiature Connector and 2 Optical connectors - Transmitter and Receiver, 15 (H) x 44(W) x 80(D)mm (excluding connectors)

Features:
• The OSD139A is a small, high performance fiber optic modem capable of linking asynchronous RS232 ports (eg: computers, terminals, test equipment etc:) over distances of several kilometres at speeds ranging from DC to 60Kbps.
• The OSD139A is available with either a male (OSD139AM) or a female (OSD139AF) 25 Pin D connector.
• The unit is switchable between DTE/DCE mode (ie: Pin 2 or Pin 3 connects to the optical transmit section of the unit). This is selectable by a toggle switch mounted between the optical connectors.
• All units excluding the option L will operate from the data line plus two control lines with standard RS232 line drivers (eg: MC1488 or equivalent) operating from at least ±9VDC are employed in the host equipment.
• Power in the range of +6VDC to +12VDC may be fed to the unit via Pin 9 of the 25 Pin D connector.
