5.5 microSD Card Setting
For the device with optional code MC, by setting the
dedicated microSD card into the slot on the display unit,
the parameter setting can be stored into it. The
stored data can be restored to the device. For the
detailed function, read the user’s manual of applicable
communication type as listed in Table 1.1.
WARNING
Use only micro SD cards sold by YOKOGAWA.
Operation cannot be guaranteed when other cards are
used.
(1) Installing microSD Card
Carefully insert the dedicated microSD card into the slot
on the display unit until the slot holds the card. (see
Figure 5.5).

(2) Removing microSD Card
The microSD is released from the slot by pushing it. To
prevent from losing the microSD card, be careful to
handle the card.
IMPORTANT
If the microSD card is removed without execution of
“Unmount” on parameter setting, it may result in
the corruption of stored data and the abnormal
operation of device.

5.6 BRAIN Configuration Tool
The connection of the BRAIN configuration tool
(BRAIN TERMINAL (BT200) or FieldMate (Versatile
Device Management Wizard)) is shown as below.
Read the user’s manual of BT200 (IM 01C00A11-01E)
for the operation, and the user’s manual of BRAIN
communication type as listed in Table 1.1 for the detailed
parameter setting via BRAIN communication.
The communication signal is superimposed onto the 4 to
20 mA DC analog signal to be transmitted. The BRAIN
configuration tool can interface with this device from
the control room, this device site, or any other wiring
termination point in the loop, provided there is a minimum
load resistance of 250 Ω between the connection and the
receiving instrument.
To communicate, it must be connected in parallel with this
device, and the connections must be non-polarized. See
Figure 5.6.

IMPORTANT
Communication signal is superimposed on analog
output signal. It is recommended to set a low-pass
filter (approximately 0.1s) to the receiver in order to
reduce the output effect from communication
signal. Before online-communication, confirm that
communication signal does not give effect on the
upper system.
IMPORTANT
Restrictions exist with regard to the distance over
which communication is possible. Read the general
specifications as listed in Table 1.1.
