DL™ User Manual Rev 3 37
APPENDIX B - DL SPECIFICATIONS
PHYSICAL
Size
245 mm x 130 mm x 59 mm
Description of Enclosure
The enclosure is constructed of extruded anodized aluminum. It is sealed by two
end-caps, made of molded ABS plastic. The entire unit is closed with five
mounting screws. An access cover on the front end-cap allows the insertion and
removal of PC Cards. Seals are made of electrically conductive rubber.

VIBRATION (Random Profile)
The DL can acquire and track satellites while undergoing vibration levels as shown below. It assumes that C/No > 45
dB-Hz and that the DL is in high-dynamics mode. Assuming appropriate mounting, the DL conforms to random
vibration templates for RTCA/DO-160C, Section 8.6.2 (Curve C template), MIL-STD-202F, Test Condition I (Letter A
nominal template), and ASAE EP455, Section 5.15.1 nominal template; contact your dealer or NovAtel Customer
Service for information on the effect of the mounting bracket.

POWER MANAGEMENT
If the DL is connected to two batteries, it begins using the one with the higher voltage across its terminals. When this
voltage drops to 10.7 V DC, the Power indicator color changes from green to amber. When the voltage drops below
10.0 V DC, the battery is unusable; the Power indicator color changes from amber to red, and the DL switches to the
second battery (if available). Once battery reserves are depleted, the DL shuts itself off.
