UDC-RA

Async to 16k Sync Rate Adapter

Features / Benefits

Description

* Allows low speed Terminals to access 16K, 64k or 128k sync circuits such as radio modems or muxes

* Interface - Supports any combination of RS-232, RS-530, RS-422/449, V.35 and X.21

* Serial Data Interface cards are Interchangeable and may be mixed such as RS-232 to V.35

* Options to force control signals

* Supports option RTS in-band to DCD with the Data

* Supports Async or Sync data from Terminal Device

* AC Mains powered 110/220 VAC or DC Power

* Sturdy Metal Aluminum Enclosure

The UDC-RA Rate Adapter allows low speed async or sync RS-232 data terminal equipment(DTE) to transmit over a higher speed 16k, 64k or 128k sync data communication equipment(DCE) link. Additionally, the unit supports matched data rates for basic Async to Sync conversion such as 19.2k async over sync 19.2k. The UDC-RA devices are used in pairs, one at each end of the communications link or in multiples as when used in a multi-point or broadcast link. The UDC-RA will support bi-directional or simplex data transmissions.

The UDC-RA supports async character lengths of 8, 9, 10 and 11 bits including the start and stop bit. The low speed async interface is RS-232 and supports data rates of 1.2k, 2.4k, 4.8k, 9.6k, 19.2k, 38.4k, 57.6k and 115.2k. The high speed sync data interface supports rates of 16k, 64k or 128k and must be a clear channel with no overhead status bits being passed. The sync channel supports data interfaces for V.35, RS-530, RS422/449 and X.21.

The UDC-RA has internal switch options to force control signals. Additionally, the user may set RTS to be in-band with the data to DCD, DSR or CTS. This is useful for networks that have no control signals passed. Extended Signal Rate(ESR) is provided to ensure the async input data rate matches the sync output data rate, ensuring reliable data communications.

The UDC-RA has two TTL level interfaces for connecting each data interface module. The unit is shipped with two user specified data interfaces. Additional data interfaces are sold separately. The individual data interfaces are available in DCE or DTE formats.

The UDC-RA is housed in a sturdy aluminum enclosure and is supplied with an internal linear power supply for 110/220VAC. The unit has a three year warranty and a 24 hour turnaround on warranty repairs
