CHANGE DEVICE NAME: To rename a device, first select the device using the "Select Device" field
to the left, then enter a new desired name and press GO. The new name will then appear under
"Select Device" preceded by the device number and an = sign. For example, you may change the
name of the first device to "Boiler 1 Pressure" to make reports more understandable.
NODE PROTOCOL: Select Custom ASCII, Modbus RTU, Modbus ASCII, or a pass-through
protocol indicated by ? for the device that has been selected under "Select Device". Press GO to
enter any change. If all devices are by Laurel Electronics, the node protocol, baud rate and parity
are automatically selected in a plug-and-play mode as part of device discovery. Multiple devices
that are interfaced to the same Node via an RS485 bus can each be set up with a different node
protocol, baud rate and parity. This capability is normally only used to accommodate non-Laurel
devices.
• If Modbus TCP is used to communicate over a LAN with the Node, this protocol is
seamlessly converted by the Node to Modbus RTU or Modbus ASCII for communication
with Laurel meters and transmitters on an RS485 bus.
• The Custom ASCII protocol is simpler than Modbus RTU or Modbus ASCII.
• The ? protocol selection is a pass-through protocol where the Node simply passes through
data packets to the LAN without modification in a tunneling mode. This should only be
used to accommodate non-Laurel devices.
BAUD RATE: Select the baud rate for the device that has been selected under "Select Device".
Press GO to enter any change. If all devices are by Laurel Electronics, the node protocol, baud rate
and parity are automatically selected in a plug-and-play mode as part of device discovery.
• Multiple devices that are interfaced to the same Node via an RS485 bus can each be set up
with a different node protocol, baud rate and parity. This capability is normally only used to
accommodate non-Laurel devices.
• Available selections range from 300 to 614,400 baud. The factory default setting for meters
by Laurel is 9,600 baud. Rates higher than 19,200 baud are not supported by Laurel
devices shipped prior to 2013, but may be supported by non-Laurel devices.
• Slow baud rates of 1,200 baud and below are not recommended, since these cause unne-
cessary transmission delays.
PARITY: Use the "Parity" field to change the parity setting of the device that has been selected
under "Select Device". Press GO to enter any change. If all devices are by Laurel Electronics, the
node protocol, baud rate and parity are automatically selected initially in a plug-and-play mode as
part of device discovery.
• Multiple devices that are interfaced to the same Node via an RS485 bus can each be set up
with a different node protocol, baud rate and parity. This capability is normally only used to
accommodate non-Laurel devices.
• If "Custom ASCII" is selected as under "Node Protocol", No Parity is automatically selected
by the software.
