Real-Time Clock Synchronization Process; Tuning Antenna - Biomark IS1001 Operation User's Manual

Real-Time Clock Synchronization Process

IS1001 real-time clock synchronization should be configured using a special 2-conductor RTC
synchronization cable (please contact the Technical Services Department of Biomark at (208)
275‐0011 or email customerservice@biomark.com
1. Connect the synchronization cable between "DEBUG" ports (Mother Board connector J3) of
IS1001 readers. Connect the cable end marked "Source" to IS1001 reader you wish to be the
source for real-time clock synchronization
Note: Under normal conditions "DEBUG" port operates as Local communication port, so if
you connect the synchronization cable between IS1001 readers and power them all on, there
will be communication traffic between the ports. This communication will be confusing to
readers as they only expect to receive commands through the ports. This will lead to infinite
loop of "unrecognized command" error messages sent back and forth between IS1001
readers and will cause their CPU to overload. To avoid the later, when such condition is
detected on "DEBUG" port, IS1001 reader will automatically enable real-time clock
synchronization and set itself as the source. This means, there may be multiple IS1001
readers that will set themselves as the source of real-time clock synchronization. This is not
a critical issue but can be confusing. To ensure proper real-time clock synchronization
configuration follow these steps.
2. Power on the IS1001 reader you wish to set as the source for real-time clock synchronization.
3. Use BioTerm to establish a connection with the IS1001 reader.
For information on establishing a connection, see page 19.
4. If necessary, set the proper IS1001 reader's date and time settings by using the RDS and the
RTS commands (see page 28).
5. Enable the real-time clock synchronization and set the IS1001 reader as the source by using
the RST1 command (see page 28).
Note: You only need to enable real-time clock synchronization on one IS1001 reader. No
settings need to be changed on the remaining IS1001 readers for the synchronization to
function properly.
6. Reset the source IS1001 reader and power on the remaining IS1001 readers.
Real-time clock synchronization occurs 10 seconds after the synchronization is enabled or 1
minute after the source IS1001 reader is reset and then every 12 hours after.
Note: An off-schedule real-time clock synchronization event will occur whenever date or time
setting of the source IS1001 reader is changed.

Tuning Antenna

Note: If you are employing two or more IS1001 readers, antenna of each individual IS1001 must
be tuned while all other adjacent IS1001 systems are disabled (in standby mode or powered off).
In order for antenna dynamic auto-tuning to function properly you must perform an antenna full
tune after the initial system installation. During this process the IS1001 reader determines the
target tuning phase, the tuning phase deviation threshold and the initial tuning capacitance setting
based on the properties of your system and its environment.
The antenna full tune process is activated by establishing a connection with the IS1001 reader
and entering the Antenna Full Tune (AFT) command (see page 28).
1. Power on the IS1001 reader.
2. Use BioTerm to establish a connection with the IS1001 reader.
