2.3 The NET Connector

This connector carries one RS422/485 (software selectable) and one RS485-only commu-
nication channel. When using this connector for patient data download only the RS422/485
channel is used in RS422 mode. This channel is called the HOST-RS422 below.
The connector is of the type RJ-45. It was selected because there are a lot of cable and con-
nector material available for this kind of connector as it is also used to build LAN networks
of type 10Base-T for personal computers. Normally this way is used to connect cameras to
a host computer is when one host computer is connected to more then one camera but it
may also be used if the distance between the host computer and camera is too long for
RS232.
Next section will describe how to build an RS422 network using commonly available mate-
rials made for 10Base-T networks. Below follows the specification of the NET connector that
may be needed if other material is used.
