3.6 Connecting the Extension Cables-
Extension Cables
Any of the following extension cables can be used for connections between the DA100 main unit
and subunits or for connections between subunits.
Name Model Description
Extension cable DV200-000 Length: 0.5m
Extension cable DV200-001 Length: 1m
Extension cable DV200-002 Length: 2m
Extension cable DV200-005 Length: 5m
Extension cable DV200-010 Length: 10m
Extension cable DV200-020 Length: 20m
Extension cable DV200-050 Length: 50m
Extension cable DV200-100 Length: 100m
Extension cable DV200-200 Length: 200m
Extension cable DV200-300 Length: 300m
Extension cable DV200-400 Length: 400m
Extension cable DV200-500 Length: 500m
Connecting Procedure
Insert the plug of the extension cable in the connector until you hear a click. Since both
connectors are identical, it makes no difference which connector you use. Furthermore, since both
plugs of the cable are identical, you may use either end.
When pulling the plug from the connector, gently press the peg of the plug and pull it forward.

Note
When the following handling is done, it is necessary to carry out “system construction” to operate the
instrument correctly. After executing system construction, confirm the module information. For details,
see page 9-16.
• Connection (including addition or replacement)/removal of subunits, or unit number setting (see page 3-
7)
• Mounting (including addition or replacement)/removal of modules
Points to Note when Using the Extension Cables
• The maximum rated temperature is 60
°C;
• Never disconnect the extension cable from the connector by pulling the cable, since this might
damage the signal cable. Always hold the plug.
• When wiring the extension cable through a cable duct, or metal pipe or such, protect the peg on
top of the plug by covering it with tape.
• For extension cables of longer than 50 m connect the plug with copper foil directed towards the
main unit DA100. Applying it in reverse direction might increase noise.
• Fasten the cabels in such a way that no force is applied to the connector or the plug.
• To prevent the wire from snapping, etc. do no apply a tensile force of more than 70N.
Furthermore, do not bend the cable in a radius of 3 centimeters or less.
• For the environmental conditions for wiring, refer to Section 3.11, “Countering Noise” (page 3-
35).
Note
When several sub-units are connected, and the power is turned off of one of them, the other connected sub-
units which are further away from the main unit will not be recognized anymore.
