\documentclass[a4paper]{article}
\usepackage{pstricks}
\usepackage{pst-node}
\usepackage{multido}

\begin{document}

\begin{pspicture}(4,7)
   \psset{arrowscale=1.5}
   \multido{\iA=1+1}{6}{\cnode(1,\iA){0.25}{C\iA}}
   \multido{\iA=1+2}{4}{\fnode[framesize=0.5](4,\iA){F\iA}}
   \ncline[linecolor=red]{->}{C1}{F1}
   \ncline[linecolor=red]{->}{C1}{F2}
   \psset{arm=0,linecolor=red,angleA=180}
   \multido{\iA=1+2}{4}{%
     \ncdiag{<-}{F\iA}{C2}%
     \ncdiag[linecolor=blue]{<-}{F\iA}{C4}%
   }
\end{pspicture}
