Rs232 cable for vmrsusb

hi, i try to connect a cable to my pc with the rs232 port

in the pc i use a usb to rs232 converter and this one works

but how do i connect the cables of the rs232 cable? straigh or crossed?
on the vmbrsusb there is written:
SG SG DTR- Rx RTS+ Tx

if i connect the rs232 to the connector, it does not work

You should use a crossed cable
