Design Tips for Serviceability
Design Tips for Serviceability
Consider the concept of serviceability early in the design. Create a functional service
strategy that includes procedures for performing unit-level screening. The test must
determine whether a fault lies with the data transceiver or with the product into
which the data transceiver is integrated. The test must also screen for network
problems and human error.
Data Transceiver Accessibility
Locate the data transceiver so that the serial I/O, parallel I/O, and antenna
connections are accessible. Quick access to the data transceiver enables easy
removal and installation, troubleshooting, and functional testing.
SmartSynch Software Utilities
SmartSynch, Inc. provides the programming software utility with which to
configure the data transceiver. The PPS operates with Windows 95, Windows 98 and
Windows NT and communicates via the RS-232 serial connection. For
microprocessor-based host platforms, provide a pass-through mode that enables the
programming software utility to run while the data transceiver is connected to the
end-user’s host design or system.
Developing Diagnostic Software Utilities
A thorough serviceability plan includes a needs assessment for developing software
utilities that help you to identify communication problems among the product, the
data transceiver, and the RF network. These utilities must send commands to the
data transceiver, evaluate responses, perform network connectivity testing, and
verify data communications with the network.
Develop these utilities via the CLP command set or the internal CLP API if you are
developing an on-board/embedded application. The CLP API provides the capability
to monitor and evaluate data transceiver operating conditions and all
communications to and from the wireless network host.
The CLP command set and CLP API supports reading of a diagnostic buffer that
provides the view of the network from the data transceiver. This utility is essential
for field service engineers and service center technicians attempting to diagnose
product problems, and trace such problems to failed assemblies or mismanaged
communications links. See the "Diagnostic Mode" subsection of the "Off-Board
Application Development" chapter in the Software Integrators Guide for details.
Pager to/from e-mail and pager-to-pager communication is supported in the
ReFLEX protocol, which SmartSynch, Inc. recommends for diagnostics. An example
of this feature is sending a message to a pager worn by the technician servicing the
equipment. This enables you to perform local troubleshooting.
