Decimal number in the range of 0 = not used, 1 to 63 = Id of device.
20
Synced House Id
This parameter indicates the Screen Id of another auditorium that is currently “Interlocked”
(SYNC’ed) with this eCNA. This number only has meaning when the eCNA is in Sync Mode (SON).
Decimal number in the range of 0 = not used, 1 to 63 = Id of device.
21

(SYNC’ed) with this eCNA. This number only has meaning when the eCNA is in Sync Mode (SON).
Decimal number in the range of 0 = not used, 1 to 63 = Id of device.
23
Reset
This parameter indicates that the eCNA has re-booted. This would most likely be due to a power
up, but will also indicate any other system reset. This parameter can be used by the client to
detect a power up, allowing the client to initialize outputs if desired. This is a 1 byte value. The
most significant bit (80 Hex, 128 Decimal) is set after a reset and cleared after the eCNA status
record is sent the first time. The lower bits (0 to 7F Hex, 0 to 127) are simply incremented by one
after each reset.
Decimal number in the range of 0 to 255.
24
Bypass Flag
This parameter indicates the state of the Bypass flag. The Bypass flag can be set or cleared with
the Bypass program instruction or a programmable input. Bypass is only used with the 39440
termination board to activate or de-activate eCNA control.
Values: "BPN" = Bypass is not active, "BPY" = Bypass is activated.
25
Segment Index
Number
This parameter indicates the current segment number of the eCNA control program.
Decimal number in the range of 0 to 9.
26
Segment Name
This parameter indicates the current segment name. of the eCNA control program.
User defined text up to 14 ASCII characters.
27
CAI Command

CAI command program instruction that is used to Allow or Block serial control commands on a
CAI communications channel. This only blocks ‘control’ commands. Status commands are always
accepted.
Values: “OK” = Access with all commands, “BLK” = All control commands are blocked.

program is not set.
Decimal number in the range of 0 to 9.

This parameter indicates the current Event number. This number is cleared on program start.
Decimal number 0 to 20.
34
Future
Parameters may be added to the end of this record in future releases.
Any new future parameters will be inserted right before the checksum. Client software should be
designed to except and discard possible new parameters, but still include them in the checksum
calculation. This will provide compatibility with future eCNA firmware.
