Connecting the apC/L to the Host
P10 is the port used for connecting the apC/L to a host computer (see
Figure 2.2). A single apC/L can connect to the host via RS-232C format.
Multiple apC/Ls communicate via an RS-485 chain, but the apC/L chain
must be connected to the host through an RS-232 to RS-485 converter.
