The RF network between the RFS6000 and
the RF devices of Opticon is specially
designed for data collection. In such applications
the data is transmitted in small chunks and
gathered at the host. The communication
between the RF device and the host is
achieved by short messages sent through the
RFS6000 controller. Examples of short
messages are scanned data from one RF
device (e.g. barcode) sent to the host
computer, and responses related to the data
(e.g. name, price) sent from the host computer
to the portable RF device.
Reliable communication between the RF
devices and the controller is assured by the
protocol that is implemented in the controller.
For the communication between controller and
host firmware is available. The firmware
supports 2 protocols.
Free running protocol:
This protocol is designed for using the
controller without the need of software
amendments on the PC. It supports one-way
communication only, meaning that a return
message is sent by the controller to the host
only, the host can not send messages to the
RF devices.
Two-way protocol:
This protocol is based on the ANSI X3.28
standard. Using this protocol the host can also
send return messages to the RF devices.
Opticon has a DLL available that allows easy
development with tools like delphi and C++
Builder (Borland products).
Description of the protocol and communication
settings are stated in Appendix B.
For installation and setup of the firmware, see
chapter 4.
