DVMRe Triplex eZ 

 
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 
 

This command will restart the DVMRe Triplex 
eZ. 

Byte 1: 0xFF 

Byte 2: 0xAA 
Byte 3: 0 

Byte 4: 0x61 

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. 

 

                   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 

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.
