SNAP Radio Commands

The SNAP Radio Commands manage how the radio interfaces and synchronizes with the SNAP
processor. While the hop command changes a radio parameter as well as a SNAP processor
parameter, other radios parameters must be changed using the Radio Commands detailed in the
next section.

Command Description

hop [help

length

<hoplen>

sequence

[75|25]

Displays help screen for command

Sets/displays hop dwell time in radio and SNAP

Informs SNAP of number of frequencies in radio hop
pattern

remote [

help|

list|

Displays help screen for command

Displays remotes currently registered with the SNAP

sync [help

disable

ether

master

override

settings

slave

wire]

Displays help screen for command

Turns sync off (default)

Sets synchronization mode to use Ethernet packets

Sets SNAP as sync master

Toggles master backup override

Displays synchronization settings

Sets SNAP as sync slave

Sets synchronization mode to use RJ-11 wire ports

hop

When using co-located or synchronized access points, used to inform the SNAP of
the hop dwell time or the number of frequencies in the hop pattern of the radio in the
SNAP. The parameter entered for

length

is set in the SNAP and the radio in the

SNAP and is the decimal value of the number of 625

µ

sec ticks in the dwell time. A

value of

16

corresponds to a hop dwell time of 10msec and is the default. When the

SNAP is being used standalone (with sync disabled) this value does not need to be
set.
The

sequence

is the number of hop frequencies in the hop pattern in the radio in the

SNAP. The default is 75 for US/ETSI operation. All other frequency bands, as set in
the radio by the

pe

command, have 25 frequencies in their hop patterns. This value is

entered as a decimal number. The sequence needs to be modified only if modified in
the radio in the SNAP.

remote

Displays the serial numbers of the radios in the SNAPs that are currently registered
with the SNAP.

sync

These commands set the operation of the synchronization signal used in co-located
SNAP networks. The default mode is the sync OFF. Sync is enabled by selecting a
synchronization method.

ether

and

wire

are mutually exclusive commands and set
