Note 1: In order to prevent instability in measured values caused by noise entering through the I/O terminals,
grounding the signal shield to a most stable earth point in the environment is recommended.
Note 2: The smaller is common mode voltage (DC and AC) between C terminals and between C and FG, the better is
measuring accuracy. Connecting between C terminals and if possible to FG will yield the best accuracy.
Note 3: Resistor modules (model: REM3-250) can be connected to 1A through 12C terminals to convert current inputs
into voltage. However, it is not recommended when TC inputs are mixed because the heat developed on and
around the REM3 affects the cold junction compensation performance. We recommend that REM3 be connected
on a separate terminal board.
Note 4: When the internal temperature sensors are used for CJC, temperature imbalance around the terminal block affects
greatly the CJC accuracy. In order to minimize such imbalance, do not use wires of large diameter which has large
heat dissipation. Be sure to close the terminal cover. Do not expose the module directly in the line of wind from a
cooling fan.

■ ETHERNET COMMUNICATION
Monitoring data and setup of the 73VR21x is possible on the
PC connected via Ethernet.
73VR21 SPECIFICATIONS
ES-7395 Rev.29 Page 16/18
https://www.m-system.co.jp/
MODEL: 73VR21
• Dedicated Protocol
A bargraph with % indication is provided on the screen to
show how much percent of the data file memory has been
used up.
Real time communication: Transmits specific data to a host
PC installed with the PC Recorder Software (model:
MSR128).
0 – 49 % used: Green bargraph
FTP communication: Transmits data stored in the CF Card
using the FTP protocol to a host PC by the 73VR Data Viewer
(model: 73VRWV) installed in it. Data can be transmitted
even during recording.
50 – 79 % used: Amber bargraph
80 – 100 % used: Red bargraph
• Hot Swapping of the CF Card
The CF Card is hot swappable: removable during data
recording. However, there may be a slight disturbance in
storing rate when the card is inserted.
• Screen Saver
Download, Upload: Software configurations created on the
73VR21x Configuration Builder (model:73VR21BLD) can be
downloaded to the 73VR21x. The configuration set up on
the 73VR21x can be uploaded and displayed on the
73VR21BLD.
The backlight is automatically turned off if the screen is
untouched for a certain time period.
• Bus Error Alert
• Modbus Protocol
Protocol: Modbus/TCP
An alarm is output at Alarm Output Terminal in case of
internal bus error.
Port No.: 502 (fixed)
IP address: Set on the recorder
• Writing/Reading Setting
Subnet mask: Set on the recorder
The recorder’s present setting can be stored in a USB flash-
memory. Setting stored in the memory can be read in to the
73VR21x.
Default gateway: Set on the recorder
Max. number of 73VR21x connected simultaneously: 2
