This startup manual is for the ADAM-4541
Part No: 2003454101 3rd Edition
June 2014
Overview
Fiber optic transmission offers the benefits of wide
bandwidth, immunity to EMI/RFI interference, and secure
data transmission. The ADAM-4541 can be used as an
RS-232/422/485 point-to-point or ring connection for
transmitting and converting full/half-duplex signals and
their equivalents within a ber optic environment. Fiber
optics are the perfect solution for applications where the
transmission medium must be protected from electrical
exposure, lightning, atmospheric conditions or chemical
corrosion.
The ADAM-4541 is specifically designed to link
various machinery equipped with RS-232/422/485
communication ports (such as computer systems or
manufacturing machines). Using standard ST connectors,
the module's ber optic ports can accommodate a wide
range of ber optic cable sizes, including 62.5/125 µm.

Startup Manual 2
Switch and Jumper Settings
ADAM-4541 provides three DIP switches that users
can congure the settings for their applications. SW1
and SW2 set the data format and baud rate of serial
communication. SW3 sets the Transmission mode.
SW1
Switch 1 controls the data format. Data can be 9, 10, 11 or
12 bits. The factory default is 10 bits : one start bit, eight
data bits, one stop bit and no parity bit.
*Default setting
When using the converter in combination with other
ADAM modules, do not change the default setting of the
converter, since ADAM modules have a xed data format
of ten data bits. The option of changing to 9, 11 or 12 bits
is for use with other modules (other than ADAM modules)
that have different data formats. Should you change the
ADAM module’s data format, be aware that you will also
have to change the data format on all the other modules
in the network.
SW2
Switch 2 sets the baud rate for RS-485 auto ow control.
The options range from 1200 bps to 115.2 kbps. The
factory default is 9600 bps. Be aware that when you
change the baud rate, you also have to change the baud rate
for all of the connected modules accordingly. You can refer
to the table below to make sure when you need to set SW2.

SW3
The ADAM-4541 can support ring operation. By setting
the DIP2 of SW3, the ADAM-4541 can be set as "Ring"
or "Normal" mode. We will introduce more about ring
operation in the later chapter.

Note: When using RS-232/422 in ring mode, both position
9 of SW2 and the baud rate need to be congured. And
the device MUST be connected to prevent the possibility
of communications failure. For example, using RS-232
with a baud rate of 9600 kps in ring mode, both position 4
and position 9 need to be switched ON. But only position
9 needs to be switched on in normal mode.
Startup Manual 3
Ring Operation
Several ADAM-4541 modules can be cascaded to form a ring connection. With a circumstance that users plan to use
a HMI/SCADA to connect multiple kinds of IO device with ADAM-4541, users can apply ring architecture to save
lots of cost caused from the number of modules and the length of optical ber. Following diagrams demonstrates
the Ring application. Ring Operation mode is set by DIP2 of SW3.
Limitation
While applying ring operation, please notice the following limitations.
It only supports the half duplex.
Up to 50 ADAM-4541 can be connected over a distance of 2.5 km.
Under ring operation, RS-232/422/485 all need to set SW2 for baud rate.
