Display Interface Connection; Display Interface Assembly (Dia-1010/Dia-2020) Viewed From The Rear - Notifier AM2020 User Manual

DIA-1010 and/or DIA-2020 provide access to the system CPU and the optional SIB, and an EIA-232
unsupervised printer interface (refer to Figure 2.7-1). When terminal supervision is not required and the terminal
(if present) has no keyboard, the DIA-1010 and/or DIA-2020 provide an EIA-485 interface which may be used to
connect an LCD-80 (in Terminal Mode).
