ADAM-5510/P31 5-3
Chapter 5
5.2.2 Failure to communicate (with ADAM-4520)
If the ADAM-4520 RS-232 to RS-422/485 converter is used to connect
your host computer and ADAM-5510/P31, correct and consistent
baud rate settings are required to allow the system to communicate
normally. Please refer to Section 5.2.1.
5.2.3 Incorrect cable connections
In normal operation, you may use either the RS-232 port or the RS-485
port on the ADAM-5510/P31 to download programs from the host. A
cross-over DB-9 cable is required for this operation. The downloading
will not work if you use a straight-through DB-9 cable.
5.3 ADAM-5510/P31 kernel program
5.3.1 System doesn't work even when installation is correct
If you have correctly installed Advantech Paradym-31 on the host PC,
connected the host and the ADAM-5510/P31, and made all necessary
hardware settings, but you still cannot download programs, please
check the system kernel using the following steps:
(1) Connect another host PC and the programming port of the
ADAM-5510/P31 using a straight-through DB-9 cable. You can keep
the previous connection unchanged.
(2) Execute the ADAM-5510/P31 utility program on this second host
PC. Enter the Terminal option, and push "Reset" of ADAM-5510/P31.
(3) If the reset processes run normally, try to download the program
from the first host PC with Advantech Paradym-31 again. It should
work.
(4) If downloading still fails, or the reset of the ADAM-5510/P31 is
abnormal, you have to re-write the kernel program to the ADAM-5510/
P31 as described below.
(5) To re-write the kernel program to the ADAM-5510/P31, keep the
connection as mentioned in (1) above. Execute the ADAM-5510/P31
utility program. Run the Program option.
