This command briefly sounds the radio’s piezo buzzer for testing. It
should be used only from the
CONSOLE Port.
Example Response:
buzzer: Starting test
buzzer: Test complete
clkmode Clock Mode (Subrate Radios Only)
Usage:
clkmode [<internal|exttx|looped|extdce>]
This command displays or sets the source of the radio’s transmit clock.
For synchronization purposes, several different clocking schemes can
be used. See Table 10 on Page 23 for the combinations of radio band-
width, data rates and modulation types that are available for subrate
radios. Table 11 on Page 24 shows the combinations available for full
rate radios.
Subcommands:
internal—Internal oscillator sources TC; RC derived from far end
of radio link (default).
exttx—ETC accepted from external equipment on EIA-530 inter-
face; RC derived from far end of radio link.
looped—Recovered RF (RX) clock; TC is synchronized to RC;
RC is derived from far end of radio link. Note: Do not use looped
clocks at both ends of any radio link.
extdce—ETC and ERC are accepted as inputs on the EIA-530
interface.
NOTE: Earlier versions of the software may display the Clock Mode
as NORMAL instead of INTERNAL.
Firmware Version 2.4.0 and Later – Use the
clkmode command to
determine which port has been selected to drive the timing at the inter-
face.
Firmware Version 2.3.1 and Earlier – This command allows the var-
ious possible clock sources to be prioritized. As timing sources become
available, the highest-priority source will be chosen by the system. If
attaching to the network or equipment that provides timing, a universal
form of the command would be
clkmode 1 2 3 4 internal. If attaching to
equipment that will provide looped-back timing, a universal form of the
command would be
clkmode remote internal. If both ends of the link pro-
vide looped timing, the internal clock source should be selected at one
end by entering
clkmode internal. Note that at least one end of the link
should have either network or internal timing selected.
