Modes
The ID Controller operates in two Modes: RUN and TEST Modes.
RUN Mode
In this Mode, the ID Controller operates as specified upon a command sent from
the host controller, and sends the result of the operation to the host controller as
a response.

TEST Mode
Communications testing can be conducted between the ID Controller and a DC
in the off-line state. The ID Controller repeatedly communicates with a DC at
1-second intervals. During communication with the DC, the HEAD Indicator
lights. When the processing has been completed, an end code, which is the re-
sult of the processing, is displayed on the monitor.

In the TEST Mode, two kinds of tests can be conducted: Read and Write Tests.
The Read Test repeatedly reads 1-byte data, while the Write Test repeatedly
writes 1-byte data. At this time, however, the contents of the DC’s data have not
changed. Use this TEST Mode for initial checking of the system.
Write Command Memory
A write command executed by this Controller is recorded until either the next
write command or the Power reset is executed. The write commands of the Con-
troller include write, auto write, and polling write commands. The recorded write
command can be executed by a repeat command.
