Raveon Technologies Corp.
9. SkyLine Compatibility
9.1.
General
The
FireLine
RF modem has built-in compatibility with a radio modem made by
Sonik Technologies, Vytek Wireless, and Cal Amp called the
SkyLine
. In most
applications, Raveon’s
FireLine
modem can communicate with
SkyLine
modems,
provided the
FireLine
is properly configured. There are two versions of the
Skyline, a wide-band version running at 9600 bps over the air, and a narrow-
band version running at 5142bps over the air.
9.2.
Configuring FireLine to Communicate with a SkyLine
To configure the
FireLine
modem to talk to an old
SkyLine
modem, the user must
configure the
FireLine
with these commands:
ATR2
7
This command tells the
FireLine
modem to operate with an over-the-
air baud rate of 5124 bits per second. This is the baud-rate of all
narrow-band (12.5Khz spaced) SkyLine radio modems. Wide-band
SkyLine radios operated at 9600 baud over the air. The command to
set the
FireLine
to 9600 baud over the air is
ATR2 5
.
ATR5
8
This command tells the
FireLine
modem to send 8 bytes of pre-amble
before every transmission.
MYID 1234
The MYID of the
FireLine
modem is set with the
ATMY
command or
the MYID command. The default MYID of the SkyLine was 1234.
TOID FFFF
The TOID of the
FireLine
modem is set with the
ATDT
command or
the TOID command. The default TOID of the SkyLine was FFFF
(broadcast address).
A quick-configure command is included in the
FireLine
, to allow it to be easily
switch to the
FireLine
mode. The command is “
SKYLINE
”. When in the
configuration mode, enter
SKYLINE
, and the modem will reconfigure itself as a
narrow-band SkyLine modem, with
TOID = FFFF
,
MYID=1234
, 80 byte packets,
20mS serial port time out, channel 1 frequency, over-the-air baud rate 5142.
9.3.
Use of the DM3472 Wide-band Module
The
FireLine
modem may be configured with a DM3472 wide-band radio module
to communicate with the Sonik SL-UC wide-band SkyLine radio modem at
9600bps. To do so, the following parameters must be set. All other
configurations will stay the same as a standard
FireLine
.
The
FireLine
radio modem must he a wideband configuration, with a –S on the
end of the part number. (ie RV-M5-UC-S2)
Note: This requires that the radio type be changed to 5, and the peak deviation
set to 3.0 kHz.
ATRT
5
Set the radio type to 5. This must be the first parameter that is
configured.
SKYLINE
Set the SkyLine protocol mode.
