Reader Control Functions — Command Group 6
Group 6 commands set reader control functions such as reader ID, communication protocol, output pulse,
and RF control.
60NN Set Reader ID Number
#60NN sets the reader ID that will be sent in the auxiliary data field (Command #311).
Uppercase or lowercase characters are allowed for NN; for example, hex digits A though
F or a through f
where
NN = 00 to FF (hex for 0 to 255, factory default = 00).
Reader response #Done
610 Select Basic Communication Protocol (Factory Default)
#610 enables the basic communications protocol.
Reader response: #Done
611 Select Error Correcting Protocol
#611 enables the error correcting protocol.
Reader response: #Done
Caution
Do not switch to ECP (Command #611 Select Error Correcting Protocol) unless the host is
prepared to acknowledge each reader transmission.
612NN Select Error Correcting Protocol Timeout
#612NN selects the timeout interval for ECP. This timeout applies to the transmission of tag,
report, and error messages and to the receipt of host commands. The transmit timeout
is initiated immediately after the end-of-message sequence CR/ LF is transmitted. If the
host does not acknowledge the message within the specified interval, the reader times
out and retransmits the message.
The receive timeout is initiated upon receipt of the start-of-message character (#). If the
end-of-message character (CR) is not received within the specified interval, the reader
discards the partially received message and resets its receiver.
Uppercase or lowercase characters are allowed for NN; for example, hex digits A
through F or a through f.
The value for NN specifies the timeout interval as follows:
ms 50 * NN for NN = 01 to FE (1–254)
where
FE Factory default (12,700 ms or 12.7 seconds)
