Product DIP Switches Setting

E5-CAT driver apply 7 DIP switches to set E-CAT address, details as following:

E-CAT ID Table

ID	S1	S2	S3	S4	S5	S6	S7
Reserved(Default)	On	On	On	On	On	On	On
1	Off	On	On	On	On	On	On
2	On	Off	On	On	On	On	On
3	Off	Off	On	On	On	On	On
4	On	On	Off	On	On	On	On
5	Off	On	Off	On	On	On	On
……	……	……	……	……	……	……	……
126	On	Off	Off	Off	Off	Off	Off
127	Off	Off	Off	Off	Off	Off	Off

Note: The calculation formula of the ID of E-CAT is as follows: ID = 1 * S1 + 2 * S2 + 4 * S3 + 8 * S4 + 16 * S5 + 32 * S6 + 64 *S7. The default ID value is 0, 0 indicates the broadcast address, you can set other addresses or higher address through the host computer or other software.

E-CAT Baud Rate: 100MHz

Note: S8 is reserved for dial code, can be defined according to customer needs
