Installation and Wiring
Connecting Extension Bases to an Extension Module
Verify that the power of the DR/DS400/DS600 has been turned off before connecting the
extension module/extention base.
Mount the extension module onto the sub-unit. The module cannot be mounted to the DR
recorder itself. Wire the extension module to the extension base with an extension cable. You
can wire a maximum of three extension bases to one extension module at the same time. It is not
possible, however, to wire extension bases in such a manner that the total sum of modules already
mounted on the sub-unit and the extension bases being wired exceeds the maximum number of
modules (four for the DS400 sub-unit and six for the DS600 sub-unit) allowed for mounting on
the sub-unit.
Either a 10-channel universal input module (DU100-11 or DU100-12) or a 10-channel DCV/TC/
DI module (DU200-11 or DU200-12) can be mounted onto each extension base.

Set this switch to ON for the last extension
base in the connection.

Select an unused slot number.
Either a 10-channel universal input module
(DU100-11 or DU100-12) or a 10-channel
DCV/TC/DI module (DU200-11 or DU200-12)
Wiring Distance
The last extension base in the connection can be located at a maximum distance of 30 m from the
sub-unit.
Setting of Terminator On/Off Switch
Set the terminator on/off switch of an extension base to ON for the base that is the last in the
connection. Set these switches of all other extension modules to OFF.
Setting of Slot Numbers
Select an unused slot number for each extension base. This can include, however, a slot number
for an extension module. The following figure shows how the numbers you set correspond to the
positions of slots and relate to channel numbers.
