4-2 How to Wire to Host Device
4-14
Correct Usage
A host device must send the next command in 10 ms after checking a response from an antenna. When you use an RS-
232C/485 converter, etc. in the host device, the command must be sent after the command transmission has been
enabled completely. When the command has been sent completely, switch into the receiving state within 10 ms. Other-
wise, the communication with the antenna may fail.
