For details, see the operation manual for the MM-122A.
①RS-232C
One MM-122A is connected even when the communication method of the
MM-122A is set to “232Sy” for the setting change or “232Fr” for the
measured-value reading.
②RS-485
Up to thirty-one MM-122As can be connected when the communication
method of the MM-122A is set to “485Sy” for the setting change. When
“485Fr” is set for the measured-value reading, only one MM-122A is

①Security Setting of Microsoft Excel
Since the MA-716A uses the macro function of Microsoft Excel, the
security*1 setting of Microsoft Excel 2003 is required.
Select Tool →Macro →Security from the menu bar. Set the security level to
Middle *2 or Low *3.
*1 When the security level is set to Middle or Low, defense against a virus
using the macro function weakens. Use software for virus so that it does
not cause any trouble if a virus invades macro.
*2 When the security level is set to Middle, a warning message for macro
appears when you open a file.
*3 When the security level is set to Low, a warning message does not appear.
If a file which is not using macro is infected by a virus, a warning
message is not displayed.
②Opening a File
Open the file copied in Chapter 4 (2) on Microsoft Excel. *4
When the security level is set to Middle, a warning message for macro
appears when you open a file. Select Validate Macro.
