SCS-104 Version History
Send Stored Messages (XT30/XT50 and XTLplus only)
SCS-104 Version 103 (10/16/17) supports the Send Stored Messages feature of upcoming panel firmware Version 172. If Send Stored Messages is enabled, an XT30/XT50 or XTLplus Series panel with Version 172 firmware will store any messages that are not able to be sent while communication to the receiver is down. Once communication is restored, the panel will send all stored messages to the receiver. Each stored message provides the number of minutes ago the event occurred. This feature requires upcoming SCS-150 firmware Version 104.
Receiver Check-In Messages (XT30/XT50 and XTLplus only)
This feature supports upcoming panel firmware Version 172 and requires SCS-150 firmware Version 104. Prior to Version 172, if a panel failed to deliver a check-in message to the receiver on IP1, the panel attempted to send a check-in message on IP2. If IP2 was programmed to communicate with a different line card, that line card would generate an S17 (communication restored) message. Depending on the programmed fail time, the line card pointed to by IP1 could also generate and S16 (communication failed) message. If the line card pointed to by IP2 was different, then on the next successful check-in attempt to IP1, that line card would generate an extra S16 (communication failed) message. Beginning in panel firmware Version 172, the panel sends a special check-off message to the receiver’s IP2 once communication is restored to IP1. This improvement prevents the SCS-104 from generating an extra S16 (communication failed) message after communication with IP1 is restored. Send Stored Messages must be enabled in the panel for this feature to be available.
Panel Communication
The SCS-104 has been enhanced to allow for better panel communication when dealing with low signal levels caused by bad phone lines, carrier exchanges, and other issues.
TCP Session Reset
SCS-104 cards now automatically reset TCP sessions where panel communication is lost for more than 15 seconds. When a bad session is reset, the inactive socket is closed and the card resumes accepting network communication.
Caller ID Display
With Version 103, SCS-104 cards now collect caller ID information when the calling number is delivered in the message field.
Subnet Mask
The SCS-104 has been updated to allow the subnet mask to be used independently from the IP address. Previously, the SCS-104 would ignore a class B subnet mask if the IP address was 192.X.X.X or higher.
Card Reset
An issue where the SCS-104 would intermittently reset itself has been resolved.
The SCS-104 Receiver Line Card now supports the 256-bit AES encryption option for XR550E Control Panels using Version 104 or higher software. The SCS-104 supports both the new 256-bit option and 128-bit to maintain compatibility with existing control panels. Either 128-bit or 256-bit encryption can be enabled in panel programming for NET or CELL communication paths. Once enabled in the panel, the SCS-104 automatically communicates with that panel using the appropriate encryption.
When using an SCS-104 to dial out to a panel, the SCS-104 would hang up if the panel did not answer within 40 seconds. Version 101 (5/9/13) now hangs up after 90 seconds to allow more time to establish connections with panels that have a high number of Armed/Disarmed Answer Rings programmed.
The SCS-104 Receiver Line Card now correctly applies network line programming changes from the SCS-150 processor. Previously, if Network Line Enable was set to YES, and then changed to NO to turn off network operation, the SCS-104 would continue to receive network messages until the line card power was cycled. This issue did not occur for digital dialer programming of the SCS-104 Line Card. Note: Both the SCS-104 and SCS-150 must be updated for this change to take effect. Please see Technical Update (TU-0660) for SCS-150 details.
On occasion, the SCS-104 line card could take longer than necessary to time out and close a failed network TCP communication session with a panel. This was only observed when a panel was connected to a local network experiencing communication troubles. If the panel retried multiple times to transmit a message, the SCS-104 could have experienced a temporary reduction in the number of available TCP sessions for network communication. If this condition occurred on a line card supporting panels with a Supervision Fail Time of less than 6 minutes, System Message 72 (WARNING: Network/Communication Path Trouble) could display for multiple accounts. SCS-104 Line Cards with Version 101 (5/24/12) software now appropriately close failed TCP sessions. This issue did not occur for panels using cellular or digital dialer communication.
Contact ID
The SCS-104 Line Card now accepts Contact ID (CID) signals when used with SCS-150 Processor Cards using Version 103 (12/29/11) or higher.
First Communication Type
Select DD to enable all dialer lines on the line card to communicate with panels using the DMP digital dialer communication format. Select CID to enable all dialer lines on the line card to communicate with panels using Contact ID format. To change the communication type, press any select key to display the options. Default is DD. If the receiver cannot communicate with the panel using the first communication type, the receiver attempts communication using the second communication type.
Second Communication Type
Select DD to enable all dialer lines on the line card to communicate with panels using the DMP digital dialer communication format if the panel doesn’t respond to the first communication type. Select CID to enable all dialer lines on the line card to communicate with panels using contact ID format. Select NONE to have no second communication type. To change the communication type, press any select key to display the options. Default is NONE.
Line Level Diagnostics
SCS-104 Line Cards with software Version 101 (11/17/11) now provide Line Level Diagnostics for active Digital Dialer (DD) lines when installed with the SCS-150 Version 103 (12/29/11). This feature is available from the membrane keypad of the SCS-1R under System Status or from browser programming under Receiver Diagnostics.
Line Level System Status
This displays the signal strength and caller ID information for each line. The card number is listed first: Card 8 in the example. Range is 1-8. The line number is listed second: Line 1 in the example. Range is 1-4 for all enabled SCS-104 lines.
The number in the top line of the display represents the signal strength of the last call in -dBM. The second line displays caller ID information of the last call. If caller ID information is unavailable, the ANI/DNIS information is displayed. If ANI/DNIS information is unavailable, then NO DATA displays. Press the COMMAND key to advance to the next DD line card. If no more DD line cards display, the display advances to the programming menu.
When a panel requests a time update from the SCS-104 over network communication, the correct month is now sent in the update. Previously, the month number sent was the number for the prior month.
