Installation
one serial mode may be used at a time per port. Each communication port includes a set of 12 jumpers divided into two columns. These
jumpers must be set according to the serial mode desired.

Com 3)
The two serial ports (COM2 and COM3) of the M4SSER may be configured by setting jumpers for either RS-232 or RS-485/422. Only
The figure below shows the two sets of jumpers as they appear on the M4SSER. Note that the two sets are identical except for the
• For RS-232, install all jumpers to the left. In addition, install all termination jumpers (C1–C4 or D1–D4) to ensure reliable
• For RS-485/422, install all jumpers to the right. Choose jumper location for 2-wire/4-wire and for termination based on your

Jumper
For RS-232, remove the C2W/D2W jumper and install
jumpers on C1 through C4 or D1 through D4.
For RS-485/422, set jumpers C1 through C4 or D1 through
D4 all the same, depending on whether the M4RTU/DAS is
physically the last unit in the communication link (jumpers in)
or not (jumpers out).
