Troubleshooting Common Problems
Hardware
• Refer to "Cabling Diagrams" on page 74 to verify that your direct or modem connection
cable is configured properly.
• Verify that the hardware key is in place. SAM52M will not start if the key is not found.
In addition, SAM52M 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 SAM52M versions are compatible. Due to changes in
program structures between various register versions, incompatibility issues may arise.
Samsung ER 5200M 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-5200M are all default (9600 BAUD, NO PARITY,
8 DATA BITS, 1 STOP BIT) and that SAM52M is set the same.
SAM52M Software
• Create a new store by selecting Create New from the Stores menu. See "Creating a
New Store" on page 10.
⇒ 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 SAM52M. You must Receive (Upload)
information from the ECR. Refer to "Receive Programs from ECR (Upload)" on page
40.
• If problems persist, try rebooting the PC.
• If you have trouble loading a program from SAM52M to a register, be sure the register
memory allocation is set large enough for each file.
