Bit Rate
The bit rate represents the data rate at which the target product operates. Possible values
range from 1200 bps to 230,400 bps.
Parity
The serial equipment may have a parity of odd or even. It may also not have parity check;
most communication devices do not use parity.
Line Driver
By default, your device automatically detects the electrical line interface of the serial port
(RS-232 or RS-422/485). However, if your device cannot properly detect the electrical level
(for instance when there is too much noise on the line or too much signal attenuation due
to excessive cable length), you can use the line driver setting to force its electrical line
interface.
Here are the possible line driver settings, where
-d
indicates that the auto-detection mode
is activated, and
-f
, that the line driver is forced:
Warning: If the line driver is forced to an RS-422/485 setting, you will not have access to
the CLI unless you use an RS-485 to RS-232 converter or perform a hardware
reset (described on page 31).
RS-422/485 Operating Mode
The operating mode setting enables you to establish the way your RS-422/485 serial
equipment will interface with the S1100w device. The supported modes are:
„
RS-422 4 Wires
„
RS-485 4 Wires
„
RS-485 2 Wires
