The UDC-IC interface converter allows the user to purchase a single product to convert interfaces between any combination of RS-232, RS-422/449, RS-530, V.35, X.21, HSSI, RS-485 TTL and Current Loop. The unit supports data rates up to 10Mbps.

The UDC-IC has two TTL level interfaces for connecting each data interface. The unit is shipped with any two user specified data interfaces included in the price. Additional data interfaces are sold separately. The individual data interfaces are available in DCE or DTE formats. Each data interface has the ability to force commonly used control signals such as RTS, CTS, DSR, DTR, Ring Indicate, Control and Indicate. 

The data interfaces may be mix and matched in any combination. Installation is fast and simple by plugging the DTE interface card into Port B and the DCE interface card into Port A. In all installations, Port B will always provide timing to Port A. 

The UDC-IC has status LED’s for each attached data interface which allows the user to visually confirm the presence of control signals. Options for inverting data, clock and delays for RTS or CTS. 

The UDC-IC utilizes state of the art digital CMOS technology to provide a feature filled product at a very affordable price. Our Field Programmable Gate Array (FPGA) design has allowed us to offer this product with a wide selection of data interfaces. 

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

The UDC-IC has a three year warranty and a 24 hour turnaround on warranty repairs.



The Interface Converter allows interconnection of a DCE and a DTE device which have different data interfaces, converting signal levels and the physical data interface
