Communications
Communications Mode
Some ID-Software Communications options are unique to the software, and do not have corre-
sponding programming symbols. These options are explained below.
Reader Packet Format
Data that is sent from the reader to the host in Raw format is sent without packet framing
or check characters. One-Way communication is in a raw format, no rID-Softwareonse is
expected from the host, and data is not resent.
Packetized data is sent with framing (a preamble communicating the amount of data to be
transmitted, and a postamble containing error detection) and check characters, and a rID-
Softwareonse is expected from the host.
Two-Way communication is in packet format.
Reader to Host Packet Size
The Reader to Host Packet Size is the amount of data (in bytes) that is sent to the host in
packet format. This feature allows you to set the maximum allowable packet size.
Expect Host RID-Softwareonse
When Expect Host RID-Softwareonse is enabled, the reader will re-transmit data if it
doesn’t receive acknowledgement from the host.
Reader Send Retry Count
Reader Send Retry Count sets the number of times the reader will re-transmit data
before abandoning further send attempts. The minimum retry count is 1 , which represents
the initial transmission.
Host Acknowledgement Timeout
The Host Acknowledgement Timeout is the amount of time (in seconds) that the reader
will wait for an acknowledgement from the host before re-sending data.
