3.4 RS232C Serial Interface
The RS232C interface has been retained on the Lx/Ls Series II power source models for
backward compatibility with the Series I products. It functions exactly like it did on the first
generation products.
Note: If a USB cable is plugged into the USB interface connector of the power source, the RS232
interface will be disabled. Remove any USB connection to use the serial port.
The RS232C interface is factory enabled for all Lx/Ls models, except those ordered with the
optional
–LAN interface. Models with the –LAN option have the LAN interface enabled and the
RS232C port disabled.
Note: If the –LAN option is installed, jumper W2 on the range/relay board (Assy P/N 7004-716-1)
must be installed. This jumper must be removed to enable the RS232C serial interface.
Changing this setting requires the top cover to be removed. Contact customer service
(
[email protected] ) to obtain authorization to perform this setting
change.
