From this screen, you will be able to configure both the address of the MPC 128 and the type of serial interface you will be
using, (RS-232, RS-422, or RS-485). For information on option 3 Terminate RS-485, refer to section
4.2.1 Address
Option 1 of the Serial Interface Menu opens the Serial Address screen shown in Figure 6. The Serial Address screen
allows you to set a 2-byte hexadecimal address for the MPC 128. This address is used by the FLEXNET software to
communicate properly to the serial port. Set the address for the MPC 128 and then when setting up the parameters for serial
communications in the FLEXNET software, set the address to the same address as the MPC 128.
4.2.2 Valid Addresses
Addresses can be set from 00 to FE hexadecimal. The unit only responds to commands sent over the serial bus that contain a
matching address. The only exception is the address “FF” which is a broadcast address. All units will respond to a command
containing FF as the address regardless of its current address. For this reason, FF should not normally be used as a unit
address.
