RS232/422/485 and GPI to Fiber Transceiver (CWDM)
The ODT 1540 is a multi-function CWDM compatible module which (when used with another ODT 1540 in the remote location) will extend the reach of serial RS232, RS422 or RS485 as well as two GPI (general purpose I/O) up to 40km over fiber. 18 wavelength sections are provided for CWDM use.
A single RJ45 connection can be configured for RS232, RS422 or RS485 serial standards. A separate RJ45 connector is provided for two electrical GPI inputs and outputs. Serial communications and GPI are transmitted and extended over the same fiber link.
The ODT 1540 is protocol agnostic. It supports all standard and proprietary protocols at data rates ranging from 300 to 460K Baud (auto sensing and auto adjusting).
The integrated dip switch located on the device provides precise control over the serial mode of operation with selections for the serial standard, serial termination, RX/TX crossover and RS422/485 data direction (automatic or manual). Data activity LEDs are provided for the serial port and the GPI port under the respective RJ45 connectors.
The ODT 1540 supports mixing and matching of serial standards. For example: the transmitting module can have a RS232 input, and the receiving module can be set for RS422 output.
The ODT 1540 is 100% plug and play, no software drivers are required.
