For the second example, where connect Raspberry PI to a HP Procurve switch 2610-24; We will need the converter plate of TTL to RS232, already used in previous deliveries; with WRTNode the connection will be direct between ports UART.
Kwa mfano wa pili, ambapo kuunganisha Raspberry PI kwa ya Swichi HP Procurve 2610-24; Tunahitaji kubadilisha sahani ya TTL kwa RS232, tayari kutumika katika kujifungulia awali; na WRTNode muunganisho itakuwa moja kwa moja kati ya bandari UART PATANIFU.
