16 • CYMOD 4520
2.2 Setup
Objective of Setup
Normally, it is not necessary to setup the CYMOD 4520. The default
configuration of this communication module is 9600 bps, and data format of 8
data bits with 1 start bit, 1 stop bit, and no parity check. Note that the data format
is reserved to be compatible with other brand's communication port; it should
not be modified if only CYMODs are used in a system. The baud rate can be
configured according to the application's requirement.
Setup Equipment
A screw driver is necessary to open the case. Software, power supply, and wiring
require no additional installation equipment.
Setup Procedure
Only the hardware switch setting can be setup in CM 4520. The user can set the
speed of the serial interface ( RS-232 and RS-422/RS-485 ), and the serial
data format. The speed and the data format on the entire RS-485 network must
be identical.
To setup the CM 4520, use the screw driver to open the case, then change the
switch setting. The new setting is available after power up. The cover must be
re-installed and locked carefully. Do not scratch the surface of the circuit while
setting it up, otherwise the surface coating or the circuits themselves can
be damaged.
(Note: For Harware Rev.C1 or later, there is switchless baud rate
adjustment; the baud rate, parity and data bits adjust automatically.)
Default Setting
♦ 9600 baud rate
♦ 10 bits series data format : one start bit, eight data bits, one stop bit,
no parity check
