RS-232/485/422 SERIAL OPTIC FIBER MODEM (SUN-RS244)
The SUN-RS244 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. SUN-RS244
converters are used to extend serial transmission distance up to 2 km (multi-mode fiber) or up
to 20 km (single-mode fiber). Note that the RS-232 and RS-422/485 interfaces cannot be used
on the same SUN-RS244 at the same time to convert to fiber.
The SUN-RS244 Series incorporate a method for automatically detecting the serial signal baud
rate by hardware (Auto Baud Rate Detection). This is an extremely convenient feature for the
user. Even if device 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:
• Auto sense serial signal rate, zero delay automatic transmission
• 500Kbps the highest rate
• Three interfaces (RS232/485/422)
• Multi-mode 2KM, signal-mode 20KM |
