General Description:
The Model F422CT is a bi-directional fiber-optic to RS422/RS485 (4-wire/2-wire)
converter. The F422CT uses ST connectors for Tx and Rx Data, using Duplex 62.5
micron Multimode Fiber Cable. Data rate is specified to 115.2K bits/second (call
factory for operation up to 1.0Mbps.) and Fiber Distance Up to 1.0Km. The RS422/RS485
interface is opto/transformer isolated to 3.0KV for 1 second. An automatic TX
enable circuit, allows for any baud rate / data bits in multi-drop or point-to-point
RS422/RS485 systems (full or half-duplex). Led indicators provide data activity
information, and a removable screw terminal strip allows easy connection to
field wiring. Unit can be powered from an external power source from 9-35VDC,
with an operating temperature range for 0-65C (32-149F), and 10%-90% relative
humidity (non-condensing). Circuit board size is 3.50" x 3.00" x 1.0"
with onboard standoffs that will accomodate #6 hardware.
