DESCRIPTION

The Selectable Transmit Buffer(RDS-STB) allows DCE to DTE connections at data rates up to 10Mbps. The user selectable buffer delays are for both data and a control signal in each direction and range from 5 milliseconds(mS) to approximately 1250 mS, in 5 mS increments. The STB allows users to transmit data to

critical DCE/DTE equipment such as satellite receivers, digital service unit(DSU) or other network access device for reliable network operation while fine tuning network delay times.
An example utilizing the STB is to allow the user to even the network delays between a terrestrial and satellite network for financial transactions.

The STB has individual data interfaces that allow V.35, RS-530, RS-422/449, RS-232 and X.21 connections for both DCE and DTE interfaces. The data interfaces may also be mix and matched such as V.35-to-RS-530 connections.

The STB has status LED's for each attached device which allows the user to visually confirm the presence of control signals.

Installation is fast and simple by setting the switches for delay time, clocking and Clear To Send(CTS) control.

The RDS-STB uses state of the art digital CMOS technology to provide a feature filled product at an affordable price. The units design offers a field programable gate array(FPGA) for fast customer specified changes.

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

The unit has a three year warranty and a 24 hour turnaround on warranty repairs.
