Command Details
Initialize Command: <DEV/ICT_xx_yy'cr'
Confirmation: >DEV/ICT_xx_yy'cr''lf']
Initialize Status: <DEV/ICT_'cr'
Confirmation: >DEV/ICT_xx_yy'cr''lf']
xx = chain position = 01 to 12, or BU. Where BUselects the converter as the
backup.
yy = chain length for xx = BU (i.e. Backup converter) 01 to 12.
yy = unused if xx = 01 to 12 (i.e. chain converter)
Example 1: The following command assigns the converter chain position "1".
<DEV/ICT_01'cr'
>DEV/ICT_01'cr''lf']
Example 2: The following command assigns the receiving converter as the backup converter
in a 1:8 system.
<DEV/ICT_BU_08'cr'
>DEV/ICT_BU_08'cr''lf']
Important: It should be reiterated that only the converter physically located at the top of a
redundant rack should be assigned as the Backup unit. Likewise, assignment of chain positions in
a redundant rack should be made according to the physical allocation of each converter in the
rack (i.e. The top converter should be the Backup, the second converter should be assigned chain
position 1, the third converter position 2, etc.).
A.7.3.2 Automatic/Manual Mode
This command provides for automatic switching by the backup converter if both units are in the
Redundancy Mode. This command is only accepted by the backup converter. If a chain
converter is set in Manual Mode, the backup converter will log the occurrence and not act upon
further information from the converter until put into Automatic Mode. The default is off.
Command Details
Automatic Mode: <DEV/SAM_xx_y'cr'
Confirmation: >DEV/SAM_xx_y'cr''lf']
Automatic Status: <DEV/SAM_xx_'cr'
Confirmation: >DEV/SAM_xx_y'cr''lf']
Where: xx = 01 to 12, converter number
y = A for Auto; M for Manual
A.7.3.3 Backup Mode
This command allows the user to force a backup condition for maintenance and test purposes.
This command must be sent to the converter designated as the backup converter (i.e., “BU”).
When activated this command forces the backup converter to assume the state of the specified
chain converter and forces the chain converter offline.
