4 Electromagnetic Specifications

Note: This equipment has been tes ted and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the foll owing measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an output on a circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications not expressly approved by the manufacturer could void
the user’s authority to operate the equipment.
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation o f the dev i c e.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement.

8 Interface Specifications/Recommendations

8.1 J1708

J1708 is a modified version of RS-485. J1708 specifies 18 gauge wire with 1 twist per inch with a total network length of 131 feet (40m) maximum. The minimum/maximum voltages on the bus are specified to be -7V – +12V. The data rate is 9600 baud. The standard node in the J1708 standard is shown in Figure 8-1.
Vdiff is defined as A – B. If A – B ≥ 200 mV then the data bit is a 1, -200 mv ≤ A – B ≤ 200 mV is undefined, A – B ≤ -200mV the data bit is a 0.

Note: C1 and C2 are 0.0022 F. Caution: An RS-485 specified termination uses a 100 ohm resistors external to each node at
each end of the bus which if installed in a J1708 system can cause the network to fail/

8.2 Digital Inputs

VIL < 0.5V and VIH 1.2V. These inputs are protected with 47K of series resistance. Transients to 60V can be tolerated
with circuit damage becoming more likely above 60V.

8.3 Audio

The speaker is rated to 3W, 200 – 20,000 Hz.

8.4 GPS

The On-Board Validator uses an internal GPS antenna. Specifications taken from Telit J u p iter JF2 Datasheet [3].
