24 RS-232/RS-422/485 Option

Example

The following example shows the settings on JB4, JB5, JB6 and JB7

where half duplex RS-422/485 port 1 is terminated and biased on CTS

± and RxD ±, the full duplex RS-422/485 port 2 is set for

bias/termination on RTS ±, TxD ±, CTS ±, and RxD ±, the multi-drop

slave RS-422/485 port 3 is not terminated, and the RS-232 port 4 is

not and should not be terminated.

Technical Tips:

1. For half duplex RS-422/485 ports you typically only jumper

position G(Rev. A & B adapters) or positions F and G(Rev. C

adapters and later) on the appropriate jumper block (JB4, JB5,

JB6 or JB7) if you want them terminated.

2. For full duplex and multi-drop slave you can jumper positions D,

E, F, G(Rev. A & B adapters) or D, E, F, G, H, and I (Rev. C

adapters and later), on the appropriate jumper block (JB4, JB5,

JB6 or JB7) if you want them terminated.

3. For RS-232 ports do not jumper positions D, E, F, G, H, and I,

on the appropriate jumper block (JB4, JB5, JB6 or JB7).
