3. Enable/Disable Mics
Either of the 46-120’s two mic inputs may be enabled or disabled. This may be done globally (for all zones), on a per-zone
basis. The value of x in the general format is the Mic input (1 or 2).
EXAMPLE COMMAND (ASCII) COMMAND (HEX)
Enable Mic 1 globally 3C 4D 31 2C 4F 2F 3E
Disable Mic 2 globally 3C 4D 32 2C 4D 2F 3E
Enable Mic 1 for Zone 2 only 3C 5A 32 2E 4D 31 2C 4F 2F 3E
4. Enable/Release Paging
RS-232 control of paging allows an audio signal connected at MIC 1 to be routed for paging.
This command differs from the others in that the value of y in the general format is in the form of a 4-character mask of ASCII
“X’s” (select) and “O’s” (don’t select), with the character position in the mask denoting the Zone number.
EXAMPLE COMMAND (ASCII) COMMAND (HEX)
Enable paging to Zone 3 3C 50 4D 2C 50 41 4F 4F 58 (4F) 2F 3E
Enable paging to Zones 1 and 4 3C 50 4D 2C 50 41 4F 4F 4F 58 2F 3E
Cancel paging 3C 50 4D 2C 50 52 2F 3E
Note that it is not strictly necessary to transmit the “O” character (4Fh) for channel numbers above the highest being paged.
Thus
(ASCII) would suffice in the first example above. However, the full four characters are shown in the table
for completeness, with the extra characters in brackets in the hex version.
