Description

UOTEK RS-232/485/422 Dual-Fiber MODEM UT-2788

UT-2788 optic fiber modem supports asynchronous RS-232/485/422 communication. It is the best choice to connect remote terminal unit (RTU) with HOST or SCADA controller. It supports RS-232/485/422 asynchronous protocols; it can be mixed and matched to use 2 RS-232, RS-485 or RS-422 ports, and it supports 2 wires (half-duplex) RS-485 and 4 wires (full-duplex) RS-422 mode. The RS-485 mode supports data transmission (TXD or SD) control, this enhance the adaptation to most of the software. Optic fiber MODEM supports lots of optic connection between asynchronous serial ports. It supports 2 asynchronous serial devices to communicate under full-duplex or half-duplex via optic fiber; the communication distance can be as far as 4km at multimode, and 20km at single mode. The fastest transmission rate for RS-232 can be 115.2Kbps, and for RS-485/422 can be 460Kbps. Ports with different
electronic standards can be mixed and matched to use; it is without problem to connect RS-232 devices with RS-485/422 device. This is a good replacement of RS-232 to RS485/422 converter, which with EMI/RFT features.
UT-2788 supports two signal data transmission: transmit and receive data. At the same time, it is with RS-485/422 data transmission auto control circuit; Zero delay conversion; all the serial ports is connected via terminal block; the optic fiber is connected via two ST ports.
