Table 2-5. SDACT Troubles
Trouble Message Possible Causes / Troubleshooting
Missing Card
Indicates that the SDACT card is not communicating with the
master.
• Check the position of switch SW2 on the SDACT card. This
switch must be in the normal position.
• Ensure that no other N2 cards (LCD Annunciator, 24 Point I/O,
RS-232, DACT, or 4120 Network) have a card address of 8. If
the SDACT Card is addressed as card 8, replace the SFIO
card.
• Check the N2 harness (733-953). Make sure that all wires are
attached to the correct terminals and all connectors are secure.
Wrong Card
Indicates that the card at address 8 is some type other than an
SDACT card.
Ensure that no other N2 cards (LCD Annunciator, 24 Point I/O, RS-
232, DACT, or 4120 Network) have a card address of 8. If the
SDACT Card is addressed as Card 8, replace the SFIO card.
Central Station
This trouble indicates that the SDACT attempted to dial the central
station and communication was lost. Contact the central station to
determine whether the problem is on the customer or central station
end.
Phone Line 1
Phone Line 2
This trouble indicates that the phone line has been disconnected.
Swap a known working card in place of the SDACT and see if the
problem corrects itself. Check the line’s physical connections;
contact the phone company for additional troubleshooting help.
Program Checksum
This trouble indicates that the on board SDACT card checksum test
has failed. Use the SDACT programmer to reload the SDACT
database. The database is either corrupt or was never loaded.
DB Version Mismatch
This trouble indicates that the configuration loaded on the SDACT
card differs from the configuration on the master. Make changes to
the 4010, build and download the 4010, then merge the new .PTF
file in the SDACT programmer and download the SDACT card.
