This appendix provides information for the implementation of the Guardian serial radio modem into an existing

DL-3400 analog system.

Figure 38 Guardian Serial Radio Modem and DL-3400

APPLICABLE PRODUCTS

DL-3400 Analog Transceiver and Guardian X00 Wireless Modem.

APPLICATION

The DL-3400 is an analog transceiver that can operate in the VHF, UHF, and 900 MHz frequency bands depending on

the part number ordered. The radio can operate at 25 kHz bandwidth or 12.5 kHz also depending on the part number

ordered.

The Guardian serial radio modem can operate at VHF, 200 MHz, UHF, and 900 MHz frequencies. The radio will operate

at 25 kHz of bandwidth or 12.5 kHz of bandwidth. The user can select the operating mode by using the Guardian FPS

(Field Programming Software) and selecting the proper bandwidth. Reference Part Numbers and Availability and the

Guardian Field Programming Software chapter in this User Manual for additional information about Guardian

frequency ranges and bandwidth selection.

The Guardian and DL-3400 are OTA (over-the-air) compatible. A Guardian will be configured through the FPS to match

the parameters of the existing DL-3400 system.

HARDWARE

Although the Guardian and DL-3400 are OTA compatible, there are physical differences between the two product lines.

- Antenna connector

o DL-3400 – Female SMA connector

o Guardian – Female TNC connector

o See Table 10 for a list of Coaxial Adapter Cables that are available for use with the Guardian.
