PROGRAMMING AND OPERATIONAL HINTS

- Normally the Guardian will be programmed for FSK mode since this mode provides flat audio response for data

applications.

- When interfacing into an existing DL-3400 / DL-3282 radio modem system, always verify the DL-3400 programmable

parameters and program the Guardian accordingly.

- Information about the DL-3282 is available in the technical manual PN 001-3282-003. Contact the CalAmp Wireless

Networks Group,

wngsupport@calamp.com, for manual availability.

- The DL-3282 modem is programmed using a series of DIP switches located inside the modem. Default settings are

Bell 202 with Equalizer, CD – Active High, Normal mode – On, RTS/CTS delay – 240 mSec.

- Guardian CD polarity should be set for Active High, which is the default setting of the Guardian CD parameter.

- Ensure that Pin 4 of the User Port interface is set for CD output.

Note: The Guardian can operate from 10 to 30 VDC. The DL-3282 modem can operate from 7 to 16 VDC. Care must be

taken to prevent overvoltage damage to the DL-3282 modem.
