Model277

RS-232/485/422 to Fiber Converter

(SS：single mode single fiber)

Introduction:

Model277 is one kind can offer RS-232/485/422 serial port carry

transparent optic fiber modem of transmission to get end to user, no

need patch cords set up, switch over automatically, and can detect

and examine the signal speed automatically, zero delays time to

transmit automatically. Model277 adopt optic fiber transmit, have

isolate protection, data privacy is fine, working steady, data, such

threats to communication equipment as the wave is welled up and

interfered with electromagnetically that the effective one has

prevented the abominable environment from being struck by

lightning, can work in the abominable and dangerous environment

reliably.

Can be used in occasions such as various industrial control, course

controlling, traffic controlling and intellectual district , especially

suit the bank, electricity and interfering with environment

department and system with the special requirement

electromagnetically.

Wall mounting installation

DIN-Rail Installation

Troubleshooting instructions:

Check the connections according to the connection diagrams. Make

sure the power LED is ON and the RX & TX LEDS are OFF when

there is no data communications. Perform a loop back test on two

Model277 converters. Attach the two Model277 converters by

attaching the device A to the device B using a SS Fiber Optic Cable.

Connect the Model277 RS-232 port or RS-485 port or RS-422 port

to a PC. Send ASCII Characters from a hyper terminal program

from one converter to the other. This will test both the transmit and

receive functions.

Model277 FAQ:
