11.6 Connecting to the Ports
The following shows some examples of connections between port 1 and 2 and peripheral units. When creating a
connection cable, check it thoroughly in advance according to what the purpose of its use is.
11.6.1 Port 1
Port 1 of the MICRO-EH is a communication port that uses the RS-232C protocol as interface. It is also a dedicated port
with which to perform communication by the H series dedicated procedure (high protocol). Table 11.8 lists the types of
peripheral units and cables that can be connected to port 1.
