Example

The following example shows the settings on JC, JD, JE and JF where RS-422/485 port 1 is terminated on RTS ± and TxD ±, the RS-422/485 port 2 is set for bias/termination on RTS ±, TxD ±, CTS ±, and RxD ±, the RS-422/485 port 3 is not terminated, and port 4 is set for RS-232 on jumper block JB and therefore should not be terminated

Technical Notes:

1.For full duplex and multi-drop slave you can jumper positions 1, 2, 3, 4, 5, and 6, on the appropriate jumper block (JC, JD, JE or JF) if you want them terminated.

2.For RS-232 ports do not jumper positions 1, 2, 3, 4, 5, and 6, on the appropriate jumper block (JC, JD, JE or JF).
