NOTE: The baud rate set on the TIO device should always follow the
baud rate of the host PC or PLC it connected to.

5.3.13 Submenu “Communication Settings”
This menu selection allows the configuration of a digital communication interface
speed (Baud rate) and device RS-485 bus address (only applicable for optional
RS-485 interface)
The following settings are available for “Communication Settings” (see Figure 5.7):
a) Baud Rate Settings (Tabular entry)
This option determines device digital communication interface speed
(Baud rate) and can be set to one of the following:
1200
2400
4800
9600
19200
38400
57600
115200
By default the device shipped from factory with baud rate set to 9600.
b) RS-485 Bus Address (Numerical entry)
The standard TIO comes with an RS-232 interface. The optional RS-485
interface has two hexadecimal characters of the address which must be
assigned. By default each flow meter is shipped with RS-485 address set
to 11 hexadecimal. When more than one device is present on RS-485
bus, each device should have a unique address. The two characters of the
address in the hexadecimal representation can be changed from 01 to FF.
NOTE: Based on “Device Function” (device function as flow meter or
flow controller) settings, different parameters may be displayed in
the Process Information (PI) screen (See Figure 5.4) and different
features of the TIO device may be enabled or disabled (set point
control only enabled when TIO is configured as flow controller). Also
some features (e.g. Flow Alarm) may have different behavior. Be
sure the “Device Function” parameter is set according to the actual
device being used.
