CONFIGURATION
1. Communications Configuration: Communications parameters for the ASPMETER
series are field selectable for your convenience. Please see the Product Diagram
section (page 2) for selector location. The following parameters are configurable:
• Baud Rate: 9600, 19200, 38400
• Parity On or Off
• Parity: odd or even
• Wiring: two or four

2. Address Configuration: Each Modbus device on a single network must have a
unique address. Set the switch block to assign a unique address before the device
is connected to the Modbus RS-485 network. If an address is selected which
conflicts with another device, neither device will be able to communicate.
3. Address the ASPMETER as any whole number between and including 1-246. Each
unit is equipped with a set of 8 DIP switches for addressing. See below.

4. To determine an address, simply add the values of any switch that is on.
For example:
40
=
LSB MSB
Switch number 4 has an ON Value of 8 and switch number 6 has an ON Value of 32.
(8 + 32 = 40). Therefore, the address for the ASPMETER is 40.
See the Address Setup section (page 8) for a pictorial listing of the first 63 switch
positions.
DEFAULT DIP SWITCH SETTINGS
The ASPMETER includes two DIP switches, as shown below. Switches are shown in
their default positions.
