MC-III™ EXP Flow Analyzer Section 4
Security Setup
Setting a keypad security code will prevent unauthorized personnel from altering calibration data or resetting
totals, and the security function is recommended to preserve data integrity of the system. The MC-III EXP’s
keypad security feature is disabled at the factory.
To enable the security protection, check the “Keypad Lock” checkbox on the System Setup screen, and enter
a four-digit lock code in the eld below the checkbox. (Do not use “0000.”) The security feature will be
activated the next time a user attempts to access the keypad.

Slave Address
The slave address allows the MC-III EXP to communicate with other devices via Modbus
®
. It is a number
that ranges from 1 to 65535, excluding 252 to 255 and 64764. If a Modbus
®
request message contains the
matching slave address, the device will respond to the request. In network arrangements, the slave device
must have a unique address. For more information about Modbus
®
communications, refer to the protocol
manual section.
