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).
