RS232 LINK INPUT
The rear panel RS232 Link Input provides serial control of
virtually every machine function, parameter and setting.
This connector will also be used by the Slave machines in a
Multi-Machine set-up; the Master machine in such a set-up
interchanges control data with the Slaves through its RS232
Link Output connector. Thus RS232 control from an external
control system is still possible with multiple machines, as it is
only the Master machine which needs to communicate with the
external control system. See page 42 for details regarding Multi-
Machine interconnections.
This section of the manual provides details of the port
parameters and an abridged serial command list, which includes
the main machine functions. The full RS232 protocol is beyond
the scope of this manual, but can be referenced or downloaded
as a .pdf file at www.hhb.co.uk.
Pinout
The rear panel connector is a D9M. The pinout is shown in the

NOTE : The CDR-882’s RS232 port must be enabled by the
REMOTE ON command before any further RS232 commands will
be accepted. Once REMOTE MODE has been enabled, neither
the front panel controls nor the RC-882 handset will operate,
and operation of the CDR-882 can only be controlled with the
RS232 Link Input or the Parallel Remote Input. REMOTE MODE
must be disabled before the front panel controls and handset will
function again.
The ENABLE REMOTE MODE command causes both drives to
enter STOP mode if they are not already in it.
NOTE : KEY OFF cancels the FFWD and FREW commands.
