Notes for Series 1500 Intercom Installers Regarding the Memory Card
Series 1500 memory cards have two uses: Storing intercom conguration data and upgrading the intercom system
rmware.
• Storing the conguration of the intercom system for later retrieval is the primary use for the memory card. This can
save time from one installation to the next if the installations are similar. The system settings can also be retrieved
from the memory card in case of a system upgrade or replacement.
• To store conguration data on the memory card, insert the card into the hub and perform a WRITE TO MEM.CARD
operation in the SETUP menu (See Model 1550 manual). Then remove the card and store it onsite in a safe,
designated location. In the same manner, write the conguration data to an additional card if copying the settings to
another system is desired.
• To retrieve conguration data from the memory card, insert the card into the hub and perform a READ FROM
MEM.CARD operation in the SETUP menu (See Model 1550 manual, or page 13 of this guide).
NOTE: It is NOT necessary that the memory card remain in the slot in the hub during normal operation.
Intercom system rmware may be upgraded if necessary with a memory card containing rmware les.
Firmware Upgrade Instructions
The Series 1500 Intercom was designed to be rmware upgraded in the eld if necessary. In order to perform a
rmware upgrade, a memory card with the desired rmware level is required, and the resident rmware on the system
must be at version 1.2 or higher.
1. Insert memory card into slot in Audio or Audio/Video Hub.*
2. Attach 1550 Field Setup Display to Counter Station.
3. Press and hold SETUP key on Counter Station for one second.
4. Select Menu Option 5. MEMORY CARD.
5. Select Menu Option 4. FIRMWARE UPGRADE.
6. Use the VOLUME keys to scroll through system components; the current rmware level for each system component
is displayed as well as the rmware level resident on the memory card.
7. Touch the HOLD key to select/deselect the listed component for upgrading. Touch the MIRROR key to select/deselect
all components.
8. To begin the upgrade, touch the SETUP key twice.
The rmware upgrade may take several minutes to complete. If power is disconnected from the hub during the
rmware upgrade, the procedure must be repeated. Once the upgrade is complete, all indicators on the hub will return
to normal operation.
* 1 on 1 Systems may be upgraded by temporarily inserting a hub into the system.
