Device part of <Figure 1> input Com Port(COM1), Baud Rate(4800), Parity Bit(2), Data Bit(7), Stop Bit(1) respectively, according to setting of controller.
Note) Baud rate can set parameter 11.11 of Mentor II controller. (parameter 11.11 : 0 = 4800bps )
Mentor II communication driver read schedule
Read schedule setting parameters are as follows:
1) Station – station number. ( value of parameter 11.12 )
2) Read data type – don't care.
3) Read start address – reading paramter number. ex) 10.01 -> 1001
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – fixed to 1.

You can set Mentor II controller by using 'writing settings'.
Digital Write
Digital write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION station number. ( value of parameter 11.12 )
3) ADDRESS writing parameter address. ex) 10.02 -> 1002, 1.13 -> 113
4) Extra1 don't care.
5) Extra2 don't care.
Write example 1)
PORT:0, station:1, ADDRESS:1002, Extra1: , Extra2 : 0
The setting parameter shown above is forward direction speed setting example of 1 station Mentor II controller.
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION station number. ( value of parameter 11.12 )
3) ADDRESS writing parameter address. ex) 1.05 -> 105
4) Extra1 don't care.
5) Extra2 don't care.
Write example 1)
PORT:0, station:1, ADDRESS:0106, Extra1: , Extra2 : 0
The setting parameter shown above is maximum speed of forward direction setting example.
Please connect RS-485 communication cable to PL2 socket of Mentor II controller. ( you can select 2 Wire or 4 Wire connection, according to setting of 11.13 Parameter )
<Figure 2> is diagram of RS-485 communication cable for 4 Wire connection.
