RS-232
RS-232 defines three types of connections: electrical,
functional, and mechanical. This interface is ideal for the data-
transmission range of 0–20 kbps/50 feet (15.2 m). It employs
unbalanced signalling and is usually used with DB25 connectors
to interconnect DTEs (computers, controllers, etc.) and DCEs
(modems, converters, etc.).

(modems, converters, etc.).
RS-422
A differential interface that defines voltage levels and driver/
receiver electrical specifications, RS-422 is typically more immune
to noise or voltage spikes that may occur on the communication
lines.
to noise or voltage spikes that may occur on the communication
lines.
With differential interfaces, RS-422 also supports greater drive
capabilities over longer distances. It can communicate over cabling
lengths of up to 4000 feet (1219.2 m). Its signal levels range from
0 to 5 volts.
lengths of up to 4000 feet (1219.2 m). Its signal levels range from
0 to 5 volts.
In addition, the RS-422 serial transmission standard defines
driver and receiver electrical characteristics that enable you to put
one driver and up to nine receivers on the line at the same time.
one driver and up to nine receivers on the line at the same time.
RS-485
Backward compatible with RS-422, the RS-485 interface is
used for multidrop applications.
As with RS-422, the RS-485 interface supports cable lengths
up to 4000 feet (1219.2 m). Plus, the signal levels for RS-485 are
the same as those defined by RS-422. Its electrical charac teristics
differ in that it allows for 32 devices to be connected
simultaneously to one line.

Universal Serial Bus (USB)
Universal Serial Bus is a royalty-free bus specification
developed by leading manufacturers in the PC and telephony
industries to support plug-and-play peripheral connections. USB
offers increased bandwidth and lower costs than conventional I/O
ports.

offers increased bandwidth and lower costs than conventional I/O
ports.
The USB is a daisychain consisting of USB hubs and peripherals
less than 16.4 feet (5 m) apart. The USB daisychain can support
up to 127 devices. Instead of opening up the CPU to insert new
boards, you make all connections outside the case to the USB
ports.
up to 127 devices. Instead of opening up the CPU to insert new
boards, you make all connections outside the case to the USB
ports.
Because USB connections are hot-swappable, you can attach
or remove peripherals without shutting down your computer.
Also, USB hubs have additional ports that enable you to daisychain
multiple devices together. Hundreds of manufacturers of PCs,
various peripherals, and software support USB.

USB Version 1.1 supports 1.5- and 12-Mbps data rates.
USB Version 2.0 is backward compatible to Version 1.1 speeds.
