Specifications of communication & I/Os Interfaces
Position Mode
RS232
RS422, RS485
WITHOUT polarization and termination resistor
RS422, RS485
WITH polarization and termination resistor
- Note -
The 3 switch configurations shown here above are the sole configurations giving satisfactory results.
That switch 3 & 4 need to have the same position (both ON or both OFF). When they are ON, it
connects the internal polarization (typ 680 Ohms) and termination (typ 120 Ohms) resistors. This
configuration applies only to RS485/RS422 lines conforming to good practices.
- WARNING -
The switch 2 is reserved and must stay OFF.
5.11. MPI port
The MPI port is easily identifiable with its light blue square
(surrounding a female DB9 connector)
