On a status display, the data distribution board shows
the status of a parliamentary voting session. A status
display requires a control PC and the Text/Status
Display software module.

To show the information, the status display receives
either an ANSI erase display code (refer to section
47.4.2.7) or a display update command. This display
update command is a dump of status information (752
bytes). It consists of:
• A start code of two byte (A5 A5).
• For the first 1,500 devices in the system, a device
nibble that contains the status values of the
contribution devices (refer to table 47.7).
table 47.7: Numeric display
Value Status
0 The delegate at this unit is not present.
1 The delegate voted 'No'.
2 The delegate voted 'Abstain'.
4 The delegate voted 'Yes'.
8 The delegate is present, but has not voted.
Note
If there are less than 1,500 devices in the
system, the remaining nibbles are always set to
00.
Two device nibbles together form a device byte. The
location of the device nibbles in the device bytes
depends on the alphabetically sorted seat number list in
the installation file on the DCN control PC.
Example:
A system contains 6 units (refer to table 47.8). For this
system, the entire display update command will be:
A5 A5 08 41 28 (and 747 bytes with value 00)
