4.2 Setup
Objective of Setup
Normally, it is not necessary to set up the CYMOD 4520. The default
configuration of this communication module is in RS-485 mode, supporting
a baud rate of 75 to 115200, with data format including 5, 6, 7, 8 or 16 bits.
Its stop bit support 1, 1.5 or 2 bits, parity types are None, Odd, Even, Mark and
Space. Note that the data format is reserved to be compatible with other
brand's communication ports, it should not be modified if only CYMOD brand is
used in a system. There is no need to configure the baud rate.
Setup Equipment
A screw driver is needed to adjust the dip switch (next to the USB connector)
for protocol type selection.
Setup Procedure
Only the hardware switch setting can be set up in CM 4530. The user can select the
protocol types from the RS-422, RS-485 or RS-232 interface. The speed and data
format on the entire network must be identical.
To set up the CM 4530, use the screw driver to adjust the dip switch beside the
USB connector to select the protocol type. The new setting is available at
power up.
