ct, cS, cA - Communication Parameters
ct - communication type: Specifies the type of
communication port being used by the PL
µ
S control. It
contains both an RS-232 and an RS-485 port. RS-485 is
the default setting. Both of these ports share the DB-9
connector located at the top of the power supply section.
The type of port being used on the PL
µ
S must match the
type of port being used by the device communicating with
the PL
µ
S.
cS - communication Speed: Specifies the baud rate (bits
per second) that the PL
µ
S communication port will operate
at. It must be set for the same baud rate as the device
communicating with the PL
µ
S control. The choices are:
4800, 9600, 19200, and 38400 baud. 9600 is the default
setting.
cA - communication Address: Each control can have
a unique communication address (0-255) because multiple
controls can be wired to the same host device in a RS-485
network. This allows the host to send information to a
specific control while the other controls will ignore the
information. A PL
µ
S control will ignore incoming information
if the address that information specifies does not match the
communication address of the control.
rU - rPM Display Update Frequency

NOTE: On units manufactured prior to date code 9740,
