RS232: Uses the OIT's 9-pin female connector labeled PLC[RS232].
The following selections use the OIT's 9-pin male connector labeled PLC[RS485]
PC[RS232].
4. Select baud rate, parity, data bits, and stop bits. Use Maple Systems' Controller Information
Sheets or the PLC manufacturer's operations manual for information on the communications
parameters required by the PLC. These parameters have to match the PLC settings.
5. Parameter 1 and 2 are used to configure a delay time for the OIT. The time set on these
parameters is the time the OIT will wait before sending another request for information.
Parameter 1 is used in the Protocol level and Parameter 2 is used at the Operating System
level. Refer to the Controller Information Sheets if these parameters are required. Parameters
3-6 are not used.
6. Set the OIT Station No. used by some protocols that require the OIT to have a unique network
address. Consult your Controller Information Sheets for information on the protocols to
which this parameter applies.
7. Set the PLC Station Number or Node Address of the PLC with which the OIT will
communicate.
8. Multiple HMI and HMI-HMI link speed: Used when connecting multiple OITs to a single
PLC. Disable this setting if you are connecting only a single OIT to a PLC. For more
information on connecting multiple OITs, see Connecting Multiple OITs to one PLC at the
end of this chapter.
9. Connect I/F: Allows selection of the method by which multiple OITs can be daisy-chained.
The options are Serial or Ethernet. If Ethernet is selected, configure the Local and the Server
IP addresses. For more information, see Connecting Multiple OITs Using the Ethernet Port
at the end of this chapter.
10 PLC Block Pack: Determines how many words are read from the PLC in one
communication cycle. For more information on this feature, see PLC Block Pack at the end
of this chapter.

RS485 default: The selected protocol determines 2 or 4 wire.
RS485 4W: Forces RS485 4-wire configuration.
RS485 2W: Forces RS485 2-wire configuration.
Ethernet: Uses the RJ45 10BaseT connector.
