### Settings of External Device

Speed is set up by setting up the parameter by which a monitor is carried out by display of External Device. Other setup is fixed values and cannot be changed.

Setup Items | Setup Description
--- | ---
SIO Type | RS232C
Speed | Sets up with a parameter (refer to procedure).
Data Length | 8 bits
Parity | Even
Stop Bits | 1 bit
Flow Control | None

##### Procedure

The setting method of speed is explained to an example for 30i-Model A.

1. Permit the parameter writing.
   Press the [OFFSET] key of an External Device operation board, and select the [Setting].
   Change "0" of parameter writing into "1", and press the [INPUT] key.

2. Setting the parameter for display connection.
   Press the [MDI] key of External Device operation board, and shift to MDI mode.
   Press the [SYSTEM] key in MDI mode and the parameter screen is displayed.
   Press the [Next page] and the parameter input screen is displayed.
   Input the "3119" into parameter No. and the 3rd (3119. 3) bit is set to 0.

3. Setting the speed.
   Setting the 1st (13101. 1) bit of parameter No.13101 to 1, and the setting value is written in parameter No.123.

Setup Description (Dec) | Data Rate (bps)
--- | ---
9 | 2400
10 | 4800
11 | 9600
12 | 19200

NOTE

- When the 1st bit of parameter No.13101 is 0, a transfer rate is 19200bps fixation. When communicating by 19200bps, operation of Procedure 3 is unnecessary.

4. Turn off the power supply of External Device, and turn on the power supply again.

NOTE

- The touch panel function on the LCD of the CNC cannot be used simultaneously with the Display.
