 ECD UDC-RDS Low Speed Rackmount: Test, Stage, and Simulate Network Delay Times


The UDC-RDS_LS and UDC-RDS-ECO allows users to test/stage critical low data rate testing of DCE or DTE equipment while simulating network delay times. The unit provides a realistic simulation of physical network behavior with respect to time delays, clock rates and interface control signal passage. The unit supports user data rates of 300bps up to 1.024Mbps while providing delays from zero to a maximum of 1 second on each way per physical data link. 

By using the UDC-RDS in place of or in series with a real data link (WAN) a wide variety of error conditions can be introduced under controlled and testable conditions.

The unit has two data port interfaces that support RS-232, RS-422/449, RS-530, V.35 and X.21. The data interfaces can be mix and matched where applicable, such as a V.35-to-RS-530 connection. 

The UDC-RDS also allows the user to pass or force control signals. The control signals are also delayed along with the user data.

The unit is configured via accessible front panel dip switches and is available in a stand-alone or rack mount chassis. The user has no software to load as all configurations are within the UDC-RDS. Installation is fast and simple by setting the internal switches for Delay Simulation, Clocking, Carrier Operation and RTS to CTS delay. All clocking and signal crossover are provided within the UDC-RDS. 

The UDC-RDS has status LED’s for each attached DTE or DCE device which allows the user to visually confirm the presence of control signals. 

The UDC-RDS is housed in a sturdy metal enclosure and operates on 110/220VAC.
