1-4 1756-MVI Module Overview
Configuration Jumpers
Three configuration jumpers are located on the 1756-MVI module’s
printed circuit board, as shown in figure 1.3.
Figure 1.3 Configuration Jumpers
Jumpers PRT2 and PRT3 are used to configure the serial ports for
RS-232, RS-485, or RS-422 compatibility. The Setup Jumper is used to
force the console port (PRT1) to a known state.
When the Setup Jumper is installed, the module will boot with the
console port enabled at 19200 baud, no parity, 8 data bits, and 1 stop
bit. If the Setup Jumper is not installed, the module will boot with the
console port set up as configured by the BIOS Setup Menu.
See chapter 6 of this manual and publication 1756-IN001A-US-P for
more information.
