The HE45T Bluetooth protocol allows for two forms of communication:

• One Way Mode — Defined as one way communication between the reader

and host. One Way mode is only recommended when connecting to a device

well within its specified range, or if connected to a device without an

operating system (i.e., printer). There are two settings in this mode:

– Max Range (Default) — Greater range but data reliability is lower

– Max Reliability — Limits range but reliability is improved

FIGURE 1–29. RF One Way Mode Range & Reliability Codes

Note: While robust, One Way Mode doesn’t guarantee data integrity and you

may have data loss when operating in the fringes of radio range or in the presence

of radio interference.

• RF Two Way Mode — This is two way communication between the host

and reader. This requires the implementation of software at the application

level. The reader receives confirmation via packet protocol verification and

is 100% reliable. Data will be retransmitted automatically if necessary.

Note: You will need to install application software that supports packet

communication to operate in RF Two Way Mode. Microscan offers the

CodeXML Bluetooth Modem and a Windows or Pocket PC version of software

called CodeXML Router - Bluetooth Edition (BE) that provides for end-to-end
