6.3 Module Specifications
This section explains the 217IF Module specifications.
6.3.1 Hardware Specifications
6.3.2 Communications Specifications
The following table shows the communications specifications for the 217IF Module.
* The maximum baud rate of the RS-422/485 (CN3) depends on the CN1
and CN2 baud rates. If 19.2 kbps is set for CN1 and CN2, then the maxi-
mum transmission speed for CN3 will be 19.2 kbps.
