Operation SMS-7000 Modem Protection Switch
3–30 Rev. 3
3.5 Setup and Configuration
3.5.1 Utility Setup
Prior to configuration, it may be necessary to modify the following:
•
Display Contrast — Adjust for optimum viewing in local ambient lighting
conditions.
•
Remote options — If a remote is to be used, appropriate remote options must be
verified or defined from the Utility menus.
•
Modem Control Baud Rate — Select the highest common baud rate for the
modems attached to the switch.
3.5.2 Configuration
Once installed, the switch is ready for configuration to the specific application
requirements. The switch mode must be in ‘Manual’ to make most configuration
changes.
3.5.2.1 Backup
To configure the backup parameters, set the following:
•
Address — Enter a unique 3-digit decimal address for remote communications.
•
Mod/Demod, ON or OFF — Must be ON for consideration by the switch
algorithm.
•
Switching Mode — Select Dependent or Independent RX/TX switching.
•
Prime Modems — Enter prime modems to be supported by this backup.
Note: The system will not allow the same prime modem to be assigned to
backups with different switching modes. When pressing [ENTER], the system
will beep twice and remove the prime from the backup list. For valid entry, the
prime must first be removed from the other backup--or the other backup mode
must be changed to agree.
