Introduction
SD32+
System
in a single patient file. To add the DC expansion channels to a montage, click the Add button in
the Edit Montage window and select the appropriate socket number from the input label drop-
down list. The input labels available in the drop-down list correspond to the input socket labels
on the expansion box.

inputs
DC X Inputs –
These inputs, ranging from “DC X1” to “DC X8” accept analog signal inputs from
any DC device equipped with an analog output. The connector used to input a DC signal into a
DCX socket is a 1/8” male mono connector. The eight input sockets allow the unit to accept DC
inputs from multiple beds simultaneously. For example, the
Sandman Elite
software could be
programmed so that sockets “DC X1” to “DC X4” accept inputs from bed one DC devices and
sockets “DC X5” to “DC X8” accept inputs from bed two DC devices. The socket assignments on
your expansion box were set up according to your lab’s needs during installation. Only the
sockets that have been assigned to the current bed appear in the list of channels that can be added
to the montage.

J2 Serial port –
This port sends the collected signals to the COM port of the computer running the
Sandman Elite
software.
Warnings: The DC expansion box may only be used outside of the “Patient Area” (as defined
in the IEC 601-1-1 safety standard). The connections on the DC expansion box are
not isolated from the ground of your building’s electrical system. Do not allow
these connections to come into contact with either the patient or any isolated input
of the
SD32+
system as this will compromise patient safety.
All equipment connected to the DC expansion box must be certified under the
medical requirements of IEC 60601-1 deemed applicable by local authorities.
Body position sensors should be used with the DC Expansion box and not directly
connected to the
SD32+
amplifier.
