Standard Serial to Fiber Optic Converters Models FOSTCDR, FOSTCDR-INV www.advantech-bb.com PRODUCT FEATURES • Data rates up to 115.2 kbps • 4 km (2.5 mi) range • 10 to 30 VDC input voltage • Wide operating temperature • 2000V, 2-way isolation • Modbus ASCII/RTU compatible • EMI/RFI protection • TD, RD and Power LED's The FOSTCDRx line of fiber optic converters are suitable for standard industrial ORDERING INFORMATION installations. These converters extend data communications up to 4 km (2.5 mi) MODEL SERIAL FIBER INVERTED ISOLATION NUMBER CONNECTOR CONNECTOR FIBER STATE* and provide two-way optical isolation on the input and output lines. FOSTCDR Terminal Block Multi-mode ST 2,000 V - Model FOSTCDR industrial serial to multimode fiber optic converter, provides the FOSTCDR-INV Terminal Block Multi-mode ST 2,000 V  most versatile connection possible between any asynchronous full or half-duplex * Fiber is Off in the idle state. serial equipment. In addition to direct point-to-point connectivity, it is capable operating in a multi-drop mode. This allows one serial device to communicate with up to 31 other devices around a fiber optic ring. Since the FOSTCDR ACCESSORIES supports mixed serial standards, you can replace other converters and isolators MDR-40-24 - DIN Rail Mount Power Supply 24VDC, 1.7 A output power and add the EMI/RFI immunity inherent to fiber optic communications. DFMM-STST-1M - Multimode fiber patch cable ST-ST connectors An Automatic Send Data Control circuit controls the RS-422/485 driver chip, eliminating the requirement for special software. Easy to install and configure, it has an 8-position DIP switch to set up the RS-422/485 parameters and terminal blocks to connect serial signals and power. In RS-232 mode, it supports Transmit and Receive data. Handshaking signals are not passed through. What is the difference between Model FOSTCDR Model FOSTCDR-INV features an “inverted fiber state” and is suitable for applications requiring the fiber optic light to be Off in the idle state. and Model FOSTCDR-INV? The FOSTCDR keeps the light in the fiber turned On when no data is transmitted and the input signal is in the MARK state (idle). If light is lost or too low, the electrical signals go to the SPACE state. The input signal turns the light Off/On in step with the data. This model has an indicator for Transmit and Receive, if no light is received, the RD LED will come on, the RD output will be positive relative to GND (normally negative), and in RS-422 or RS-485 mode, no light will set the TD(A)- line high relative to TD(B)+. The usual voltage with light in the fiber and no signal sets the B line high relative to A (about 4.4 Volts DC no termination). The FOSTCDR-INV is the opposite. The fiber is Off in the idle state.
