Preparations for Communications
Speed Level Measurement Mode (Read/Write)
Speed Level Measurement Mode can be used to check the Tag movement speed and applicable num-
ber of bytes without connecting to a host device. In this mode, the margin available for the Tag move-
ment speed in relation to the number of bytes being accessed is displayed on the bar indicator.
The Speed Level Measurement Mode simulates writing data. Actually data is not written to the Tag.
The speed level is measured for the number of test bytes set in advance using the PARAMETER SET (SP) command.
Refer to PARAMETER SET (SP) for details.

The speed level will be displayed on the bar indicator and monitor
display.
The number of successful communications between 01 and 99 is displayed on the
monitor display. ("--" is displayed to indicate standby status.) The display will show
99 even if more than 99 successful communications were made. "EE" will be dis-
played if the first communication after the Tag entered the communications area
fails. The bar indicator will show the speed level. One LED in the bar indicator will
light for each 2 successful communications (all six LEDs will be lit after 12 successful communications). The measurement result
is also output from the USB port.
