Node Address Switches (9100 Reader only)
Communications
To Host
The AdvanTag reader communicates to the host via RS-232, CAN, or LAN ports.
Read Range
Typical read range of the AdvanTag reader is 1 to 4 inches (1 to 7 inches in Long Range
mode). Read range is dependent on the antenna design and the operational environment
in which the antenna is installed. See
“Antenna Performance” on page 30 for further
details.
SECS/ASCII
Refer to the specific protocol documentation concerning either Stream 18 SECS
messages or Asyst ASCII messages for details. The basic functions available are to read
and write attributes, read and write material IDs (MIDs), read and write data, and various
subsystem commands such as turning an LED on or off. Note that the single-page
transponders hold an 8 byte MID only and the multi-page transponders hold a 16-byte
MID and 120 bytes of data.
The TargetID (as described in the SEMI E99 and E5 standards) can be set with the
NODE ADDRESS switches; default value is 3. The SECS I DeviceID can be set through
an attribute or the Reset button. When Reset, the DeviceID is automatically changed to
match the TargetID; the baud rate will be changed to the default 9600 as well. The baud
rate can also be set through an attribute setting. Byte format is 8 data bits, 1 stop bit and
no parity. The SECS I timeouts and retries can be set through attribute settings; defaults
are T1 = 0.5 secs, T2 = 10 secs, T3 = 45 secs, T4 = 45 secs, Retries = 3.
When connected on CANbus, no two AdvanTag 9100s should have the same Target ID.
