0150-0198H 76 DVMRe Triplex eZ
9.2 Configuration and
Status
i) Data structure
Byte 1: 0xFF
Byte 2: Command Type
0xAA: (SET) Update DVMRe with data.
0xBB: (GET) Extract data from DVMRe.
Byte 3: Data Length (n)
Byte 4: Data Type
0x61: Restart DVMRe
0xFE: Send configuration data to DVMRe
0x09: Read Alarm History from DVMRe
0xFF: Read configuration and status data
from DVMRe
Byte 5: Data byte 1
Byte 6: Data byte 2
:
:
Byte x: Data byte n
ii) Sending data to the DVMRe
a) Restart DVMRe Triplex eZ
This command will restart the DVMRe Triplex
eZ.
Byte 1: 0xFF
Byte 2: 0xAA
Byte 3: 0
Byte 4: 0x61
b) Send data to DVMRe Triplex eZ
Configuration data can be sent to the DVMRe
Triplex eZ, to change the way it operates. The
data is arranged in the form of 16 byte blocks,
numbered from 1 to 213. Blocks 182, 183 and
185 are status blocks, and hence cannot be
written to. For details about the contents of
each block, contact GE-Security and request
the Block Data Structure for the DVMRe
Triplex eZ.
Byte 1: 0xFF
Byte 2: 0xAA
Byte 3: 17
Byte 4: 0xFE
Byte 5: Block Number
(1-181, 184, 186-200)
Byte 6: data[0]
: :
: :
Byte 21:data[15]
After sending a block or series of blocks, block
number 255 must be updated to signal the end of
the configuration session. All data bytes for block
255 must be set to 0.
iii) Requesting data from the DVMRe
When a message of type 0xBB is sent to the
DVMRe Triplex eZ, it will respond by sending 16
bytes of requested data.
a) Read Alarm History List
Byte 1: 0xFF
Byte 2: 0xBB
Byte 3: 0
Byte 4: 0x09
When the "Read Alarm History List" message is
received by the DVMRe Triplex eZ, it responds by
sending a start byte 0xFF, followed by ASCII
strings for every alarm event in its alarm history
list, and a stop byte, 0xFF. Each string is
formatted as follows:
dd.bmm/ddbhh:mm:ssbaa<CR><LF>
dd: index number (00 - 99)
b: space character
mm: month (01-12)
dd: day (01-31)
hh: hours (00-23)
mm: minutes (00-59)
ss: seconds (00-59)
aa: alarm number (01-16)
<CR> Carriage return (0x0D)
<LF> Line feed (0x0A)
Example: 03. 11/27 22:48:58 15
b) Read data from DVMRe Triplex eZ
Configuration and status data can be read from
the DVMRe Triplex eZ. The data is arranged in
the form of 16 byte blocks, numbered from 1 to
213. For details about the contents of each
block, contact GE-Security and request the
Block Data Structure for the DVMRe Triplex eZ.
Byte 1: 0xFF
Byte 2: 0xBB
Byte 3: 1
Byte 4: 0xFF
Byte 5: Block Number 1-213 or 255 if all
blocks are requested.
The DVMRe Triplex eZ responds to the “Read
data” request by sending all the requested data
bytes consecutively, without any start or stop
bytes.
A total of either 16 bytes or 3408 bytes will be
transmitted, depending on whether a single block
or all the blocks were requested.
