The Model 277 Series converter is equipped with a multiple interface circuit that can handle RS-232, or RS-422/485 serial interfaces and multi-mode or single- mode fiber. Model 277 converters are used to extend serial transmission distance up to 2 km (multi-mode fiber) or 20 to 120 km (single- mode fiber). Note that the RS-232 and RS-422/485 interfaces cannot be used on the same Model 277 at the same time to convert to fiber.
The Model 277 Series incorporates a method for automatically detecting the serial signal baud rate by hardware. This is an extremely convenient feature for the user. Even if a device's baud rate is changed, the signal will still be transmitted through the RS-232 or RS-422/485 to fiber converter without any problem.
****Features****
1) 500 Kbps the highest baud rate. 2) Supply three interface (RS232 & RS485 / RS422) also models with individual interface of RS232 OR RS422/485
3) Multi-mode 2-5 Kms, single-mode 20 to 120Kms. 4) Compact size. 5) Decreases Signal interference. 6) Wall-mounting (Standard), DIN Rail mounting (Optional)
