6-4 Notices for Replacement of the TM-U210/TM-U220/TM-U300 Rev. A
6.1.3 Dimensions
The dimensions of the TM-U220II (except for Type D) are somewhat smaller than the TM-U210,
such that the TM-U220II TypeA and B can be installed in the same space as the TM-U210 Type A
and B.
The dimensions of the TM-U220II and TM-U220 are the same.
See “External Dimensions and Mass” (page 1-14) for details.
6.1.4 Receive buffer size
This section applies to the serial model.
Note:
Data may be lost if the receive buffer of TM-U210 is at buffer full state when there is no FIFO
setting, or the FIFO setting is larger than 16 bytes.
However, the TM-U220II has enough remaining receive buffer space to prevent data loss at
buffer full state when DIP SW1-2 is off.
The “Number of bytes from buffer full to release full state” is larger than the TM-U210.
However, you should pay attention to the following.
