Profile: Hull Speed Data Products, Inc. is a producer of data communications accessory products. Our product line includes asynchronous to synchronous converters, broadcast device, data switches, modem eliminators, multiplexers, electrical power management and digital sharing. Our elastic interface adapter is designed to operate as a single sided device and this allows operation for isochronous & asynchronous devices to communicate through synchronous modems. We offer modem sharing interface device which are designed with asynchronous and synchronous data formats & is truly data transparent therefore, data received & transmitted by any port is passed through without changing the rate & format. Our data switches are designed to be a simple manual switch that allows the user to switch a signal from one device to another without requiring the constant switch of cables from one device to the other. Our broadcast sharing devices are designed to broadcast without the use of hardware flow control signals, which are commonly associated with contention sharing devices.
