Universal Communications Adapter

Type:  SCADA Hardware
Description:  The Universal Communications Adapter (UCA) provides integration of your SCADA and telemetry operations with satellite communications networks. The UCA interfaces with your RTUs to provide programmable scheduling, multiple holding registers to store files for local polling, programmable thresholds for report by exception monitoring, and the ability to make remote programming changes to RTUs.
Connectivity:  Modbus
Features:  Data and/or SCADA commands sent from the host are automatically delivered to the serial port connected to the SCADA client. Hardware flow control is supported; Remotely configurable receive interface permitting transmission of data to the SCADA host; Capture options include, hardware flow control, configurable EOT character or a configurable timeout period; Remotely configurable command buffer to store SCADA commands for transmission at defined intervals to reduce or eliminate the need to poll to obtain routine reports; Configurable intervals by the minute up to 31 days; Can interpret Modbus data and compare to pre-defined thresholds; Packet structure separates SCADA data/commands from transport infrastructure data or commands; Remote configuration of data or command buffer, buffer dump start time, buffer dump interval; Supports routine and error responses including user initiated poll or a pre-programmed interval response to provide easier determination of whether incoming data was generated due to an exception or a routine report; Cyclical Redundancy Check field is two bytes, containing a 16-bit binary value.
Specifications:  UCA is compatible with a variety of satellite modems and service providers; RS-232 interface configured as data communications equipment; Permits direct connection to data terminal equipment; Default settings: 4800 baud, No Parity, 8 Data bits, 1 Stop bit, configured for hardware flow control of the remote RTU or data logger.
