Communication Error
If ViewPoint is unable to communicate with the PowerScout, the Status window displays the following
message in the Status field:
“Unable to establish connection with meter, please check settings and try again.”
Try the following to resolve the communication error on a serial PowerScout:
No RS-485 option available in the PC COM Port drop-down list—indicates the PowerScout is not
properly connected or the required software driver is not installed.
Modbus Base Address Switch does not match the selected hex switch settings on th
e
PowerScout—change the switch settings.
The selected Baud Rate does not match the PowerScout baud rate—change the baud rate.
For more information, refer to the Appendix, Troubleshooting Communication Issues.
CONNECTING AND COMMUNICATING VIA AN ETHERNET (TCP/IP) CONNECTION
Connect one end of the Ethernet cable into the PowerScout and the other end into your computer or
network. To begin communicating via an Ethernet cable you must first set it up within the ViewPoint
software that came with the meter. See Ethernet (TCP/IP) Connection in the Communicating with a
PowerScout Meter section.
The meter will require power to communicate over Ethernet. Power can be supplied by connecting the
USB or voltage lines 1 and 2.
PowerScout 3037
Keep in mind that the Ethernet connection must have an IP Address in the ViewPoint software that can
either be set manually within the software with the Use Static IP address option (for a fixed address) or
obtained automatically from the router connected to the logger using the Use DHCP option (dynamic
address). Both options have advantages. See About IP Addresses further in this document.
NOTE: When Ethernet is connected, any RS-485 connection is inactivated. The PS3037 must be power
cycled with the Ethernet cable removed in order to activate the RS-485 interface.
