The RK P-CM U1 can link to a PC (personal comput er) via USB, RS23 2 , or E therne t, and through the operation interface at the
PC side (like monito ring softwar e or Microsoft Inter net Ex plorer ), management of t he rack power can be consolidated at the PC
side as shown in Figure 3- 1. Det ails will be de scrib ed in the following chapte rs.
