Q-Tech Commercial Series Q-Matrix 88
13
RS 485 Communication Protocol
Baud Rate: 57600bps/S
Parity Check: Odd parity check
Data: 16 bytes
Accumulation = 2nd data byte +
3rd data byte + 4th data byte
Q Matrix 88 Inquiry Data
The Q Matrix 88 sends inquiry data to 2
remote paging consoles, 8 remote wall panels
and extension Matrix. The new data will
feedback to the Matrix when any new data
has been checked. Any extension Q Matrix
88 will only enquire to its own 8 remote wall
panels only.
Inquiry Data To Paging Console
The Q Matrix 88 sends the inquiry data to
remote paging consoles in the following
format:
AA 10 00 00 AM (accumulation)
AA: data head
10: inquiry to the paging console
00: meaningless
AM: (accumulation = 2nd data byte
+ 3rd data byte + 4th data byte)
Feedback Data From Paging
Console
The feedback data from the remote paging
console to the Matrix after got inquiry and
ready for paging format as:
AA 11 Matrix address code zone data AM
AA: data head
11: zone paging command
Matrix address code:
01 : master matrix,
02 : extension matrix 1
03 : extension matrix 2
04 : extension matrix
3 zone data: the zone data is in 8 bytes
0 : no paging
1 : paging, ie: binary system
00000011B : zone1 and zone 2 paging
00000100B : zone 3 paging
11111111B : all 8 zone paging
AM: (accumulation = 2nd data byte
+ 3rd data byte + 4th data byte)
Status Data To Paging Console
After getting paging data from the remote
paging console, the Matrix sends zone status
data to the paging console in the following
format:
AA 1E Matrix address code zone data AM
AA: data head
1E: Zone status feedback to paging console
Matrix address code:
01: master matrix
02: extension matrix 1
03: extension matrix 2
04: extension matrix
3 zone data: the zone data is in 8 bytes,
0: no paging
1:paging, ie: binary system
00000011B:zone1 and zone 2 busy
0000100B: zone 3 busy,
11111111B: all 8 zone busy
AM: (accumulation = 2nd data byte
+ 3rd data byte + 4th data byte)
Inquiry Data To Remote Wall
Plate
If the zone is not controlled by a remote wall
plate, the inquiry data will not be sent to this
zone.
The inquiry command which is from the Matrix
to the remote wall plate is both inquiry and
status data to update the wall plate status, ie:
source input, zone volume.
The inquiry data format is:
AA 20 line input volume AM
AA: data head
20: inquiry to wall plate
line input: source input
01 : line 1
02 : line 2
..........
08 : line 8
09 : remote sources input
volume: volume level
00 : 0 level
01 : 1 level
AM: (accumulation = 2nd data byte
+ 3rd data byte + 4th data byte)
