Configuring the RF1040R/RF1070R reader
No further settings need to be made for the RF1040R/RF1070R reader. In its delivery state,
the reader is set so that it can be operated both via USB as well as the R232 interface.
A.3.4 Functions and commands
You can communicate with the Ident devices using the Ident blocks / Ident profile. The "Write"
command handles the sending of data and the "Read" command the receipt of data.
The following table shows the block-specific commands that you can execute with serial field
devices.
