straight‐throughcablewithRJ45connectorsandanRJ45‐to‐DB25maleadapter,andproceedas
follows:
1. ConnecttheRJ45connectoratoneendoftheUTPstraight‐throughcabletotheCOMport
of
themodule.
2. PlugtheRJ45connectorattheotherendoftheUTPstraight‐throughcableintotheRJ45‐to‐
