Purpose
The Communications function sets the communications type, controller address, and
baud rate for communicating with a host computer.
Type
Use SEL to toggle between RS-232 and RS-485 communications.
Address
The address must be unique for each controller installed on a network. This address is
used by a host computer running PLuSNet software to identify and send information to
a particular controller. A PLuS controller will ignore incoming information if the address
field of the communication packet does not match the address of the controller.
The address set through COMMUNICATIONS takes affect only when the DIP switch
shown in Figure 13 is set to an address value of zero. Whereas the DIP switches can
set a maximum address of “7,” the COMMUNICATIONS function can establish ad-
dresses ranging from 0-255.
Use the numeric keys and ENT to program the address.
Baud Rate
Use SEL to toggle between the available baud rates. The baud rate must match that of
the host computer. Available baud rates are:
4,800, 9,600, 19,200, 38,400
Effective with Software Versions 1.97 and higher, the communications screen
has been revised as shown below:
The termination setting should be ON if TYPE is set to RS-232, or if TYPE is set to RS-
485 and only one PS-6244 controller is in the multi-drop network. Setting the termina-
tion to OFF in these configurations may cause inaccurate RPM readings.
If multiple PS-6244 controllers are connected in an RS-485 network, termination should
be set to OFF on one and only one PS-6244 controller.
The termination setting in this screen is independent of all DIP switch settings. Use the
SOFTWARE VERSION function to determine version number.
