Setting The Network Address Switches - Dent PowerScout 3 Plus Operator's Manual

Setting the Network Address Switches

There are two rotary network address switches on a serial PowerScout 3 Plus, labeled Upper and Lower.
These two switches are used to select the BACnet/Modbus address the client uses to communicate with
the PowerScout.
The rotary switches are 16-position, hexadecimal switches. The default factory setting is hex 01. The
address is a hexadecimal (hex) value, represented by the digits 0 through 9 and letters A through F. For
example, a network address of 100 in decimal is converted to 64 hexadecimal and set on the
PowerScout 3 Plus by:
Upper switch—select 6

Lower switch—select 4

In some cases the hex value may need to be converted to decimal when entered into the RTU or data
logger. See the Appendix for a hexadecimal conversion table.
There are three rotary decimal network address switches on the PowerScout 24 used to select the
BACnet/Modbus address the client uses to communicate with the PowerScout.
The BACnet MS/TP MAC and Modbus address is a decimal value, represented by three digits: 000
through 009, 010-090, and 100-999.
Note: BACnet MS/TP masters only support addresses 001–127.
