Electromagnetic Inductive RFID System
V700
Functions
■ Transmission Functions
Note: The V700-CD
@D-V@ and V700-HMD11(-1) have different
command structures.
■ Transmission Time (Reference)
The transmission time is the time required for transmission between the Antenna and ID Tag and does not include time required for host commu-
nications.

Note: T = Transmission time (ms)
N = Number of pages (1 page = 8 bytes)
Multiple Access with the V700-CD
@D-V@
The transmission time when using multiple-access commands not
only depends on the number of bytes, but also on the number of ID
Tags in the transmission range and the combination of the ID Tags’
codes. The average values for random ID codes are given below.
(units: ms)
■ Mutual Interference Prevention Functions (Using the V700-CD@D-V@)
If there is less than 15 m between Antennas, all the Antennas must be synchronized to prevent mutual interference. This can be done using either
of the two methods described below.
Read-only Synchronization
If all the Antennas only use read commands, this method can be
used to reduce the access time.
Read/Write Synchronization
This is the synchronization method that is usually used. It enables
the synchronization of both read and write commands for several
connected Antennas.

Precautions on Using the Product near Noise Sources
This product makes transmissions to ID Tags using a fre-
quency of 125 kHz. Transceivers, motors, monitoring devic-
es,
and
power
supplies
have
parts
that
generate
electromagnetic waves (noise). These waves may interfere
with transmissions to ID Tags. Before using this product near
these kinds of devices, check that there is no adverse affect
on transmissions.
