DIP1 Section (Config)
Left unchecked, the ASCII box will leave the Reader operating in hexadecimal values, offering only
characters of 0-9 and A-F. When checked, you will be able to program and read Tags in ASCII, for
example with the data John Q. Smith. It should be noted, that if you change from hexadecimal to
ASCII or vice versa, a Tag will have to be re-programmed in order to be read. Also note that in
ASCII you will have half the characters available, 8 characters per block versus 16 characters when
using hexadecimal.
The LED Blink option allows for the change to blinking LED’s on the Reader when a Tag is
presented. Left unchecked, the LED’s will remain solid.
Direct Read Section (Config)
Default is for Direct Read Disabled, which enables the Reader to read only the UID section of Tag
memory. Set the selection to Direct Read in order to read a specific block or blocks of data in
extended memory by default. You could further choose Start Address as 01 and Byte Count to 8 to
read the first block of data, or Byte Count to 16 to read the read the first two blocks of data. However,
you can always manually read a single block by entering the Block# located at bottom right of
program and selecting “Read Block.”
Single Mode Timeout (Config)
This setting determines the amount of time a Tag must be absent from the Reader before being able to
be read and reported again. A setting of 2000 = 2 seconds. If you read a Tag and remove it from the
Reader for 1 second and re-present the Tag, it will not read again although the yellow LED will
become active. If you remove the Tag and re-present after 2 seconds, it will read and report again.
The minimum allowable setting is 100ms.
Start and End Characters (Config)
These are settings for the structure of Reader outputs of messages or Tag data. Normally we use LF
as start and CR as end of message. These can be turned off by setting to 00, or changed to
Data+CRLF by setting start to 00 and End 1 to CR and End 2 to LF, or changed to DATA+CR by
setting Start to 00 and End 1 to CR and End 2 to 00. The default is Start = LF, End 1 = CR, End 2 =
00 equating to an output of <LF>DATA<CR>.
UART Settings (Config)
Obviously these are the Data Bits, Parity and Stop Bits settings.
Reading Modes
In addition to the green LED on the Reader indicating power is applied, a yellow LED will appear
while a Tag is present to the Reader. You can change the Read Mode by selecting Single, Duplicate
or Polling. Notice that as you do so, the message OK will fill into Data In field.
Single Read Mode - will read a Tag one time upon presentation to the Reader and will timeout based
on the Single Mode Timeout setting. That timeout sequence begins only after a Tag is removed from
the Reader, meaning if a Tag is set upon the Reader for an indefinite period of time, it will never be
read a second time. Presentation of a second Tag would be immediately reported and the timeout
sequence begun anew.
