4 INSTALLATION
4.4.4
Verify that the number of devices located by the server (the total of OK, fail and new) matches
the number of devices actually installed and connected. For a first time installation, all devices
should appear as "new". (Note: A "device" is the Modbus connected device, not necessarily
the sensor. For example, an A8332 I/O module with 8 sensors connected is only one modbus
device, not eight) For further information on the LCD console, please review the console
section of this manual.
4.4.5
The EMB Hub completes a background scan for new Modbus devices every 2-5 minutes.
Increasing the RS485 Modbus timeout may increase the time required to detect new devices.
If the Modbus devices are connected after the server is booted up, the devices may not appear
on the screen for several minutes. In the worst case, allow up to 5 minutes for the
EMB Hub to locate all the connected devices.
4.4.6
If all devices are reporting properly, it is now time to connect the server to the network or
phone line for remote reporting and configuration.
