Configure: This button will allow you to change the device parameters such as the name, alarm and console
settings.
Device Configuration
When the “configure” button is clicked from the device details page, the screen will be refreshed, with the same
information, however the device name, alarm settings and console checkbox will be available.
Device Name: This field allows you to specify a name for the device such as “main building power” or other
useful name to indicate the location or function of the device. A name must be assigned to a device before the
AcquiSuite will log data for it.
Low Alarm, High Alarm: Specify a threshold for the alarm. If the data point is recorded below the Low Alarm, or
above the High Alarm levels at the time a log entry is taken, the point will be considered in an alarm state.
Console: Checking this checkbox will cause the AcquiSuite to display this data point on the LCD console. Multiple
data points are rotated about every 10 seconds. The values on the LCD console are updated when the next log
interval occurs.
Point Config: Some devices have configurable point features. The A8923-4 IO module has 4 pulse and 4 analog
inputs that require additional configuration as detailed in the next section. The H663/704 BCM product only
requires the circuit breaker name in this menu. Most data points are automatically configured and this option
may not be displayed.
Advanced: At the lower right corner of the page, an advanced configuration button may be present depending
on the Modbus device features.
Advanced Configuration Options
The advanced configuration page contains special options specific to the device you are configuring. For the
A8923-4 io module, you may specify the pulse rate speed that the pulse inputs will work at, as well as review the
4-20mA/0-10v input status. On power meters, the CT size and orientation options may be present. The device
serial number and other specific parameters will be displayed if available.
Specific options available in the Advanced Configuration page vary depending on the features available in the
Modbus Device, as well as the features implemented in the built in AcquiSuite driver.

Troubleshooting Modbus Devices
If the device you have attached does not appear in the Modbus device list, check the following:
Verify the + (red), - (black), and Shield connections are correct on all connections. Look for any connection in
the middle of the loop that may have the wires reversed, or shorted together. Check the Modbus faq on the
obvius.com website for further details on wiring a Modbus serial connection.
Verify the address settings of every Modbus device. No two devices may have the same address. Note: the
AcquiSuite A8812 uses the address 250 for the internal IO module. Do not assign this address to any other
Modbus device.
If only one device is not working, try disconnecting all the other devices on the Modbus loop to isolate the
problem. If possible, bring the failed device adjacent to the AcquiSuite and attach it with a short stub of wire
to eliminate possible wiring problems. If the AcquiSuite can find a device on the short stub, the problem is
probably a wiring related issue on the RS485 loop.
