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
Command
#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)
FE
Factory default (12,700 ms or 12.7 seconds)
FF
Disables the ECP timeout
