If you are using a M1831 Programming port cable, simply connect the programming cable
between the CPU and PC as per the connectors of the programming cable.
Table 3: Switch 1 Set-up (Serial Port)
Communications Protocol
Serial Port Dipswitch setting
Modbus Protocol (Slave device):
Transmission Mode: ASCII
Baud rate: 9600
Data bits: 7
Parity: none
Stop bits: 1
Address: see dipswitch
Switches 1-5: Modbus ID
Switches 6-8: Protocol
Switch 8 ON = Modbus default
Conet/s Protocol
Transmission Mode: RTU
Baud rate: 19200
Data bits: 8
Parity: none
Stop bits: 1
Address: see dipswitch
Switches 1-5: Conet ID
Switches 6-8: Protocol
Switch 7 ON = Conet/s default
The default operation is to use the serial port for standard communications allowing the user to
get the CPU up and running quickly and easily both on the test bench and in the field. In this
case the Serial Port Dipswitch beneath the male, sub-miniature DB-9 connector has the above
default configurations. The serial port is also software configurable using the Omniset utility or
application program, but when switch 7or 8 of the dipswitch is turned ON, then the dipswitch
setting overrides the software configuration.
To restore the settings to the software
configuration, simply set switch 7 or 8 of the dipswitch OFF.
Table 4: Serial Port Pinout
The M1260 P3 CPU allows jumperless conversion between RS232 and RS485
communications. By simply following the appropriate pinout of the serial port connector below
it is possible to connect the CPU in either mode without making any hardware or software
changes to the CPU.
