Power supply PS1 supplies the V
CC2
voltage to EVM1, and power supply PS3
supplies the V
CC2
voltage to EVM2. Power supply PS2 forces an offset
between the ground reference of PS1 and PS3. Special care must be taken
to make sure the grounds of the two EVMs are not connected together through
instrumentation or non-isolated power supply earth ground or chassis
connections. When using more than one probe with this test set up, make only
one return connection to the oscilloscope.
When used in this configuration, remove resistor R5 from each EVM to provide
single termination at each end of the bus.

Evaluation With User-Supplied Application
The EVM can also be used to evaluate the performance of the transceiver with
an existing or prototype RS-485 system. The EVM can be configured as
discussed above, and connected to the bus of interest. Depending on the
system configuration, EVM termination resistors may need to be removed to
ensure correct termination. If the EVM is used as a terminating node (at one
end of the bus), remove only R5. If the EVM is used as an intermediate node
(not at either end of the bus), remove R5, R15, and R16, and locate termination
resistors at each end of the bus. These options are illustrated in Figure 2-5.
