11. SkyLine Compatibility

11.1. 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.

11.2. 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.

11.3. 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.
