When using a Direct Read Cable, the Solinst Levelogger can be deployed before it is programmed and started with the software. The Direct Read Cable threads to the Levelogger, while the surface connector at the opposite end of the Direct Read Cable fits into the specially designed Well Cap insert. The PC Interface Cable connects to the surface connector, allowing the Levelogger to communicate with a laptop PC (see Section 2). While use of the Model 3001 Well Cap Assembly (see Section 10.1.1.3) is recommended and convenient, it is optional as long as a satisfactorily secure alternative tie off point is found for the Direct Read Cable.

Note:
There is also the option to communicate with a DataGrabber 5 or Levelogger 5 App Interface (see separate User Guides).
Solinst supplies L5 Direct Read Cable assemblies in lengths up to 1500 ft. The cable has a durable, flexible, abrasion-resistant polyurethane jacket.

Levelogger 5 Series dataloggers can be used with L5 Direct Read Cables, as well as the older style Direct Read Cables (used with Edge and Gold Series dataloggers). To use the older style Direct Read Cables, an L5–Edge DRC Adaptor is required.
Note:
When connecting an older style Direct Read Cable to an L5–Edge DRC Adaptor, only turn the coupling on the Direct Read Cable and hold the Adaptor still.
Note:
The L5–Edge DRC Adaptor contains a small, long-lasting battery (not user-replaceable). The Adaptor should always be stored above freezing temperatures and with caps on to prevent unnecessary battery drainage and protect the optical eyes.
Levelogger Edge and Gold Series dataloggers can be used with L5 Direct Read Cables, as well as the older style Direct Read Cables. To use L5 Direct Read Cables, an Edge–L5 DRC Adaptor is required.
Note:
The Edge–L5 DRC Adaptor contains a small, long-lasting battery (not user-replaceable). The Adaptor should always be stored above freezing temperatures and with caps on to prevent unnecessary battery drainage and protect the optical eyes.
Note:
When connecting an Edge–L5 DRC Adaptor, only turn the coupling on the Adaptor and hold the datalogger still. Hold the Adaptor still while threading on the Direct Read Cable coupling.

Note:
The dimensions of an older style Direct Read Cable are the same as the L5 Direct Read Cable.
Follow these steps to install a Direct Read Cable assembly to a Levelogger:
- Remove the installation cap from the Levelogger, align and connect the optical socket of the Direct Read Cable to the Levelogger by threading the coupling onto the Levelogger tightly. If using an Adaptor, thread the Adaptor onto the Levelogger first, then thread the Direct Read Cable coupling onto the Adaptor.
To ensure a water-tight seal, when connecting a Direct Read Cable or Aaptor, tighten the coupling onto the Levelogger until there is no green o-ring visible.
- The Levelogger (and Adaptor) and optical socket of the Direct Read Cable will fit through the hole in the Well Cap insert.
- The non-optical socket (wellhead end) of the Direct Read Cable will seat in the Well Cap insert.
- The two plugged holes in the Well Cap can be opened to provide an access port for a Barologger, as well as a water level meter probe.

Note:
The o-ring on the optical end of the Levelogger should be inspected regularly and replaced as required. See Section 10.2.
When removing a Direct Read Cable from a Levelogger (or Adaptor), ensure you only twist the coupling. To avoid possible damage, do not twist the strain relief on the Direct Read Cable.
