<ul><li>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.</li><li>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.</li><li>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.</li><li>The fastest transmission rate for RS-232 can be 115.2Kbps, and for RS-485/422 can be 460Kbps.</li><li>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.</li></ul> Overview UT-2788 RS-485 mode supports data (TXD or SD) sending control, thus improving the ability to adapt to various types of software and also simplifying the control mode. Fiber optic MODEM supports multiple fiber optic connections between asynchronous serial ports, it supports full or half duplex communication between two devices with asynchronous serial ports via fiber optic. UT-2788 supports two signal data transmission,all the serial ports is connected via terminal block; the optic fiber is connected via two ST ports. Specification Point to point or loop circuit (point to multi point) connection Supports RS-232 asynchronous protocol Transmission Rate: 460kbps max With optional SC, FC, ST Supports maser-slave mode Slave mode: can be used as Hub Original Packing Including 1 RS-232/485/422 Dual-Fiber MODEM 1card Slot 1Warranty Card
