SkyLine Compatibility Mode

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.

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:

ATMT 1

This command tells the FireLine modem to use a protocol that is

compatible with the FireLine. Note: ATMT 0 sets it back to the

FireLine mode.

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 6

This command tells the FireLine modem to send 6 bytes of pre-

amble before every transmission.

MYID 1234

The MYID of the FireLine modem is set with the ATDT 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 ATMK 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.

SkyLine Compatibility Notes

The TOID and the MYID of the FireLine modem will both be the same Module

Address. If the TOID from a SkyLine transmitted packet matches the Module

Address of the FireLine, the FireLine will receive the data. Just as in the

SkyLine, the FireLine will use the FF character as a wild-card address filter.
