Also found in: Wikipedia.
EIA-485
(communications, standard)(Formerly "RS-485") An EIA
serial line standard which specifies 2-wire,
half-duplex, differential line, multi-point
communications. Maximum cable length is 1200m. Maximum data
rates are 10Mbps at 1.2m or 100Kbps at 1200m. EIA-485 can
implement a truly multi-point communications network, and
specifies up to 32 drivers and 32 receivers on a single
(2-wire) bus.
Differential SCSI uses EIA-485.
Details on RS-232, 422, 423, and 485.

RS-485
A TIA/EIA standard for serial multipoint communications lines. It can be implemented with as little as a wire block with four screws or with DB-9 or DB-37 connectors. By using lower-impedance drivers and receivers, RS-485 allows more nodes per line than RS-422. See RS-232 and RS-232/485.Copyright © 1981-2019 by The Computer Language Company Inc.
