MLS-485 MLS-485 Series Network ControllersSeries Network Controllers

The Alpha Communicat ions® MLS-485 series Network Controllers
allow up to 31 RS-232 serial ports (transmit only) to be connect ed
to a receiver RS-232 port. In addition, MLS-485's eliminate RS-232
distance limitat ions. Ports may be located up to 4000' apart.
Normally, an RS-232 peripheral device must be loc ated in close
proximity to the host device.

MLS-485's prevent serial ports from attempting to communicate

simultaneously. Flow c ontrol is ac complished using the RS-232 CTS
(Clear To Send) handshaking signal. Data is c onverted to RS-485
format for transmission. This allows data to be sent over long
distances while maintining a high level of noise immunity.

MLS-485's are connect ed together t o form a network using simple,

inexpensive wiring. T wo (2) pair, #2AWG connects all MLS-485's
toget her.
