The Hardware View
10. Product Descriptions
The SB300 Series modems are designed for integration into devices that require wireless
communications such as PC’s, portable and handheld devices, metering and monitoring
equipment, and point of sale terminals.
All models provide CDPD V1.1 19.2 kbps communication. The SB320 also supports Circuit
Switched Cellular (CSC-AMPS) V.34 data rates to 16.8 kbps, and wireline (PSTN) V.34 data
rates to 33.6 kbps.
Packet Assembly / Disassembly (PAD) services are available in the modem for TCP and UDP
communications. SLIP and PPP are also supported for host based protocol stacks.
This chapter provides descriptions and specifications for the family. Individual modems are
described in separate sections below. All connector parts described are tabulated with mating part
numbers and supplier contact information in Section 10.2.4 below.
The SB300 and SB320 share common physical and interface characteristics.
10.1. Hardware Integration Considerations
When integrating one of the SB300 Series modems, read Sections 10.2 Specifications Common to
All Modems, and then the specific section for the model being integrated.
In addition, the following items need to be addressed by the integrator:
Mounting
• Effects of shock and vibration.
• Protection from dust and dirt in connections.
• Heat dissipation.
RF
• Shielding and filtering, and impacts on interference and sensitivity.
• Antenna location and type, and impacts on RF performance.
Regulatory Approvals
Although the modems were tested on their own to be compliant with FCC Parts 15 and 22, your
completed installation must be certified to meet regulatory requirements in your area.
In the USA
To use the modems in the United States of America without additional FCC certifications you
must:
1. Use an antenna providing a total system ERP (effective radiated power) not exceeding
1.5 watts for operations with the antenna located at more than 20 cm from all persons. If the
system exceeds 1.5 watts ERP then separate submissions to the FCC are required.
2. Place a warning label on the antenna (if stand-alone) or attached to the final product visible to
all persons exposed to the transmitter (if the antenna is integral with the final product). This
label must state:
