Auxiliary Port Connections
Auxiliary Port Connections
The auxiliary port offers an alternative port that can be configured to communicate by
RS232 in several modes, including daisy chain.
As with the host port parameters, the auxiliary port settings (baud rate, parity, stop bits,
and data bits) must be identical with those of the auxiliary device.
Usage:
An auxiliary port connects the Imager to a remote display or to other readers
that can display or transfer data.
Definition:
These commands set the communication parameters with the auxiliary
port, which can be used to configure menus, send data to the host, display
data transmissions originating from the host, and relay data from other
Imagers set in tandem (daisy chained).
Auxiliary Port Mode
Usage:
Can be used to transfer data faster or to match an auxiliary device.
Definition:
Determines the flow of data between the auxiliary port device(s), the
Imager, and the host..
Serial Cmd:
<K101,aux port
status, daisy chain i.d.>
Default:
Disabled
Options:
0 = Disabled
3 = Full duplex
Baud Rate, Auxiliary Port
Usage:
Can be used to transfer data faster or to match an auxiliary device.
Definition:
The rate at which the Imager and host transfer data back and forth.
Serial Cmd:
<K101,aux port
status,daisy chain i.d.>
Default:
115.2K
Options:
0 = 600
3 = 4800
6 = 38.4K
9 = 230K
Parity, Auxiliary Port
Usage:
Only changed if necessary to match host setting.
Definition:
An error detection routine in which one data bit in each character is set to 1
or 0 so that the total number of 1 bits in the data field is even or odd.
Serial Cmd:
<K101,aux port mode,baud rate,parity,stop bits,data bits,daisy chain i.d.
status,daisy chain i.d.>
Default:
None
Options:
0 = None
