Host Port RS530 The host port presents a DCE interface to the host. The interface
is terminated in a 25-way STD ‘D’ female connector.
The interconnection cable should be balanced multi-pair type with
a characteristic impedance of 100 ohms +/- 20 ohms at the data rate
under consideration.

Network Port RS530
The network port presents a DTE interface to the network. The interface
is terminated in a 25-way STD ‘D’ male connector.
The interconnection cable should be balanced multi-pair type with
a characteristic impedance of 100 ohms +/- 20 ohms at the data rate
under consideration.
