Note: 1. The communications method can be switched between RS-485 and RS-232C. Another model must be used for RS-422 communications.
2. For the number of Units that can be connected, refer to "Connection Precautions" on page 9.
3. When performing gradient temperature control, the number of control channels is limited by the group setting. For details, refer to "Gradient Group Settings"
on page 11.
