So, the signal at input T is at 6 dB.
The next byte (ç) consists of only one value.
ç = 0x87 = 135 → 135 - 132 = 3
So, the signal at output T is at 3 dB.
In the above description, the data in the BLDATA command consists of 2 bytes (1 input level + 1
output level). It is possible to tell the EF2201 to only send a subset of this information. Depending on
your control system, this could make parsing the data easier since you can ask for only the data that
you are interested in.
Suppose you were only interested in signal levels on output T. You could send the following command.
T01BLINFO01
In the above
BLINFO command, there are 1's in the positions of the data that we want and 0's in the
positions of the data that we don't want. Now, when we send a BLDATA? command or enable BLAUTO,
the Vortex sends messages of the form:
T01BLDATAo
Where the o byte is the signal level for output T.
8.13. BLINFO -- Select Information to be Reported in
BLDATA
This command controls which bytes are sent in the BLDATA command. See the description of the
BLDATA command for more information on the BLINFO command.
This command is saved to non-volatile memory only as part of a preset. The state of this command will
be restored after power-up only if a preset is saved and that preset is set to be the power-on preset.
8.14. BROAD2 -- Broadcast Arbitrary Command Strings to RS-
232 Port
This command is used to broadcast arbitrary commands to the RS-232 port for controlling other devices
(not necessarily other Vortex devices). For example, ' ' ' ' ' T01BROAD2:ATDT4048921180' would
cause the Vortex to send out 'ATDT4048921180' via its RS-232 port. If a modem was connected to the
RS-232 port, this command would cause the modem to dial the Polycom Installed Voice Business Group
in Atlanta.
