Troubleshooting Common Problems
Hardware
Refer to “Cabling Diagrams” on page 78 to verify that your direct or modem connection
cable is configured properly.
Verify that the hardware key is in place. SAM900 will not start if the key is not found.
In addition, SAM900 will check for the key at various times during an edit/polling
session. If the key is loose, or has been removed, the program will shut down.
Note:
US Robotics Sportster
Modems are recommended for remote connections (for both
PC and ECR sites).
Software
Verify that register software and SAM900 versions are compatible. Due to changes in
program structures between various register versions, incompatibility issues may arise.
SAM4s ER 900 Series
The register port must be set for PC communication. (See Service Mode RS232C port
programming.)
A clerk must be signed on.
Verify that the port settings at the ER-900 are all default (9600 BAUD, NO PARITY, 8
DATA BITS, 1 STOP BIT) and that
SAM900
is set the same.
SAM900 Software
Create a new store by selecting
Create New
from the
Stores
menu. See "Creating a
New Store" on page 11.
Set the correct Communication Port and BAUD rate. Be sure that the BAUD rate is
identical to that set in the register port.
Only enter a phone
number here if you are using a modem to poll data.
If your PC is using any
Microsoft Windows
operating systems or any software
application that has a communications-port configured, (for example a modem,
mouse or other device) you may have to check on these settings to make sure there is
not a conflict on the same communications port.
Enter information in the
Modem Initial String
field only if you have a modem that
needs to be properly configured to communicate.
Verify that store files are uploaded in SAM900. You must Receive (Upload) information
from the ECR. Refer to "Receive Programs from ECR (Upload)" on page 43.
If problems persist, try rebooting the PC.
If you have trouble loading a program from SAM900 to a register, be sure the register
memory allocation is set large enough for each file.
