A DCE device that amplifies a data signal for transmission over cable for distances beyond the RS232 limit of 50 feet, even up to several miles. Also called "limited-distance modem" (LDM) or "short haul modem" (SHM).
a preamplifier device in the output chain which is used to boost the level of the output signal. Compressors and line amplifiers are also used as line drivers.
Inexpensive amplifier and signal converter that conditions digital signals to ensure reliable transmissions over extended distances.
A circuit specifically designed to transmit digital information over long lines, that is, extended distances.
A modem alternative used when transmitting via Electronics Industry Association (EIA) cable over short distances, usually several hundred feet. (2) Device to amplify signals and reshape distorted pulses.
a device that amplifies a signal, such as the low-level signal output from a head unit
A type of encoder output. This is the general term used for a differential output driver intended for use with a differential receiver. Line drivers can be used to source or sink current, have a low output impedance and, when used with a differential receiver, have a high noise immunity, even when used with particularly long cable runs.
A circuit that provides error-free output pulses in electrically noisy environments or over long transmission lines when used with a line receiver.
A radio frequency signal generator. The line driver generates a radio signal through the guidepath or wire in the floor for trucks with wire guidance.
A communications transmitter/receiver used to extend the transmission distance between terminals and computers that are directly connected. It acts as an interface between logic circuits and a two-wire transmission line.
A signal converter that conditions the digital signal transmitted by an RS232 interface to extend reliable communication beyond the 50ft RS232 limit up to several miles. It is a baseband transmission device.
a device that ensures reliable and accurate signal transmission over long cable runs; it prevents signal degradation due to inherent cable characteristics as well as that caused by ambient electrical noise.
A signal converter which conditions a digital signal to ensure reliable transmission over an extended distance.
Output circuit that makes a larger current possible.
In telecommunication, a line driver is an amplifier used to improve the transmission reliability of a usually digital intrafacility metallic transmission line, over extended distances, by driving the input to the transmission line with a higher than normal signal level.
