ODT 1540 is a multi-function module which, when used with another ODT 1540 in the remote location, will extend the reach of a serial connection, as well as two GPI, general purpose interface, circuits, up to 40km over two fibres. A single RJ45, electrical, serial 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 duplex fibre link. The ODT 1540 is 'completely agnostic to the serial protocol used, and supports all standard protocols and proprietary protocols at data rates from 300 to 460K Baud (auto sensing and auto adjusting)'.
The integrated DIP switch provides control over the serial mode of operation, with selection of 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 also 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 percent plug and play, hot pluggable and no special software drivers are required'.
