■ Input Codes
Operation Examples of RBI and RBO
Zero suppression functions and RBO is low when the display is 0, the decimal point
is not lit, and RBI is low.
Example 1: Zero blanking is not required and the RBI input and RBO output of each
digit are open.
Fourth digit
Third digit
Second digit
First digit
Example 1
Example 2: Wired as shown when there is zero blanking. If the data of the rightmost
digit is 0, 0 will be displayed.
Example 2
Example 3: Zero blanking is valid for only the digits on the left of the lit digit and
decimal point.
Example 4: Zero blanking is valid for the second digit and the following digits that are
on the right of the lit digit and decimal point. If the first- to fourth-digit
values are all 0 and the decimal point is lit with the fourth digit, 0. 0@@
will be displayed. (There is no data in @@.)
Example 3
Note: Use RBO output for the connection with RBI input only.

• The display color will be green if the color control input of terminal 2 is set low and red if it is set high.
• All inputs are pulled up internally. Therefore high can be open.

Procedure for Making Face Plates for
M7E-02 Unit Display Unit
Custom face plates can be made according to the following
guidelines.
1. Prepare a blank Unit Display Unit (M7E-02UR2-A or M7E02UG2-A) for the desired lighting color.
2. Take transparent polyester film (with thickness equivalent to
0.188) and cut it to the following dimensions.
