Troubleshooting
Possible reasons for malfunction
汗
The TX and RX connection5 are rever5ed.
Solution:
Make 5ure the fiber connection i5 made
5o that the TX of one end i5 connected
to the RX of the other.
汗
Poor connection between the ADAM-454114542
and the communication port.
Solution:
Make 5ure the ADAM-454114542 i5
5ecure1y p1ugged into the communi-
cation port.
汗
Attenuation on the fiber cau5e5 the 5igna1 1eve1 to
drop be1ow the accepted 1eve1.
Solution:
Reduce the attenuation by reducing
connector 1o55, tran5mi55ion di5tance5, etc.
汗
The connection between the communication port5
i5 neither DTE to DTE nor DCE to DCE
connection.
Solution:
Add a converter to one of the optica1
modem5, 5o that the pin a55ignment5
from the communication port to the
Po wer su p ply
+10 ~ +30 V
We advi5e that the fo11owing 5tandard co1or5 (a5
indicated on the modu1e5) be u5ed for power 1ine5:

汗
The fiber ha5 been damaged.
Solution:
Repair or rep1ace the fiber.
汗
The ADAM-454114542 ha5 been damaged.
Solution:
U5e the 5upp1ied 5oftware to perform
a 1oop-back te5t of the optica1
modem. Thi5 wi11 detect if the modu1e
i5 damaged.
Power Supply
For the ea5e of u5e in indu5tria1 environment5,
the ADAM modu1e5 are de5igned to accept
indu5try 5t24 V
unregu1ated power.
Operation i5 guaranteed when u5ing any power
5upp1y b10 and +30 V . Power ripp1e5
mu5t be 1imited to 5 V peak to peak, whi1e the
vo1tage in a11 ca5e5 mu5t be maintained between
+10 and +30 V . A11 power 5upp1y 5pecification5
are referenced at the modu1e connector.
The power cab1e5 5hou1d be 5e1ected according to
the number of modu1e5 connected and the 1ength
of the power 1ine5. When u5ing a network with
1ong cab1e5, we advi5e the u5e of thicker wire, to
1imit 1ine vo1tage drop. In addition to 5eriou5
vo1tage drop5, 1ong vo1tage 1ine5 can a15o cau5e
interference with communication wire5.
