ID RW01L.AB-A 1.7. Connecting an external antenna In place of the antenna on the ID RW01L.AB-A, you may connect an external antenna to terminals ANT1 and ANT2 (X1). When connecting an external antenna, you must separate the two connections on the onboard antenna.
® OBID Manual ID RW01L.AB-A 2. Data traffic between Reader and Host There are three different kinds of data traffic between the reader and a host (terminal, PC, etc.). Polling and scan modes are used for data exchange between the transponder and host, whereas configuration mode is used to configure the reader parameters to the particular application.
ID RW01L.AB-A 2.1. Asynchronous interface, data formats and protocol frames The asynchronous interface can be used to configure the ID RW01L.AB-A, write data to the transponder and read data from the transponder. Communication between reader and host (terminal, PC, etc.) takes place using fixed protocols. The protocol used is designed for data bus exchange and includes a bus address.

® OBID Manual ID RW01L.AB-A 2.2. Polling mode In polling mode you can exchange data between the host and a transponder via the reader in any sequence and as often as desired as long as the transponder is in the detection zone of the reader and the host has “selected”...
® OBID Manual ID RW01L.AB-A 2.3. Scan mode In this mode the reader autonomously sends data to the host as soon as a transponder is located in its detection zone and it has read the required data. Scan mode can be configured within a broad scope, so that it can be adapted to virtually any application.
® OBID Manual ID RW01L.AB-A 2.3.1. Scan mode over the asynchronous interface If scan mode is used over the asynchronous interface, the transponder data are output either in hex format or in ASCII format (see: 5.1.3. SCAN_MODE). In addition, it is possible to preface an individual start character (SCAN_PREFIX) and/or append a terminating character (SCAN_TERM).
® OBID Manual ID RW01L.AB-A 2.3.2. Scan mode over the data/clock interface In addition to the asynchronous interface, a synchronous data/clock interface is available which works unidirectional in either Wiegand or magnetic card emulation. The serial number or data can be output on this interface.
