Data Sheet

FEATURES

› Meets EIA RS232C/D and RS422/RS485 (2 or 4-wire)

specifications

› Designed to meet full compliance with the environmental

requirements (ambient operating temperature, mechanical

shock, vibration, humidity with condensation, high-line/low-

line voltage conditions and transient voltage protection) of

NEMA TS-1/TS-2 and the Caltrans Specification for Traffic

Signal Control Equipment.

› Robust design assures extremely high reliability in

unconditioned out-of-plant/roadside environments

› NTCIP compatible

› Remote Fault Indication allows the user to determine when a

fiber break or loss of prime operating power has occurred, or

a transceiver in the field has failed

› Voltage transient protection on all power and signal input/

output lines provides protection from power surges and other

voltage transient events.

› Wide optical dynamic range: optical attenuators are never

required

› Bi-color (Red/Green) LED status indicators provide rapid

indication of critical operating parameters

› Hot-swappable rack modules

› Interchangeable between stand-alone or rack mount use –

ComFit

› May be DIN-rail mounted with the ComNet model DINBKT1

or DINBKT4 adaptors (sold separately)

› Lifetime Warranty

APPLICATIONS

› Access Control Systems

› Building Automation and Environmental Control Systems

› Computer/Data Equipment

› Fire and Alarm Systems

The ComNet™ FDX70 data transceivers provide point-to-point transmission of

simplex or duplex EIA RS232/RS422/RS485 (2W/4W) data signals over one single

mode or multimode optical fiber. The transceivers are transparent to data encoding

allowing for broad-range compatibility. Models within this series are available for use

with multimode or single mode optical fiber. Plug-and-play design ensures ease of

installation requiring no electrical or optical adjustments.
