How to Extend Tempurity™ Connections to Monitored Devices

You can use standard off-the shelf wiring to extend any Networked Robotics connection up to 300 feet.

What do I need to extend a connection?

You can use network (CAT5 class) cable to extend the reach of any Networked Robotics' interface or sensor by up to 300 feet. The figure below shows how this is accomplished when using our TPL3-series digital temperature probes. One end of the extension cable is plugged directly into the data collection port of the NTMS. The other is attached to the RJ45 coupler, and then the Networked Robotics interface or sensor is also attached to the coupler and then to the "monitored device".

The method above assumes that the extension phone or network cable is of the form of a "patch" cable with two male ends.    Use a standard and not a "crossover" cable to extend.

How should I extend Networked Robotics' TPL3 digital temperature probes?

You will be able to use either standard network (CAT5) or standard phone cable to extend the reach of Networked Robotics digital temperature probes. When Networked Robotics installs we sometimes prefer to use 6-pin flat phone wire (business phone wire) as extensions for our digital temperature probes. We find that the flat phone wire runs well at the bottom of walls and through ceilings. You can use CAT5 as well which has the advantage of being able to extend all Networked Robotics connections and is thus more uniform.

Extending your network

In some cases you may need to extend the network to the  location of the "monitored device". Your  IT or network group or electrician will be aware of the possibilities.

Extending your network with wireless infrastructure

If your organization has deployed a wireless network, you can place a wireless bridge or access point like the LinkSys WET11 in the room near the monitored site. Connect the NTMS to your wireless bridge using CAT5 cable, and the monitored devices to the NTMS. See the Tempurity User's Guide for further details.  Maintaining wireless infrastructure is different from maintaining wired infrastructure. Confirm with your IT group that the wireless infrastructure in your facility is reliable enough for data collection from critical sources.

Extending ultracold connections

The best way to extend an ultracold connection is simply to use a longer CAT5 patch cable between the NTMS and the ultracold adapter. You may also use a RJ-45 female-female coupler (shipped with the ultracold interfaces) to extend the reach of an existing patch cable by placing it in series with a second CAT5 cable.

Some RJ-45 female-female couplers on the market cross the pins internally. The correct implementation passes the pins straight through without modification. Use the couplers shipped with your unit.

Extending by Patching through Network Closets

Because the distance between NTMS hardware and monitored devices may be very long you can place NTMS hardware in your network closet and patch the digital temperature probes to the NTMS via the network wall plate in the room or laboratory. In this way you can  collect directly from the monitored device through your buildings network infrastructure. See the support document “How to connect your NTMS4 in a network closet”.

Where to get cable

Your network, telecom, or facilities group will probably have a supply of phone or CAT5 patch cable and adapters. If not, you will be able to purchase from common network or computer supply stores.

For those customers with internal electricians or other wire-termination capability, you can create your own CAT5 cable with one male and one female end to whatever length you wish. 

TPL3 digital temperature probes use IDEAL 6 position 6 contact  connectors ( Ideal part number 85-395) that are available at Home Depot.  The connector must be offset-crimped as TPl3 wire has 4 wires and the connector is 6 position.  See the .pdf here for instructions on how to recrimp the end connector of the TPL3 probe.

Wiring accessories

There are a wide variety of wiring accessories to help you run cable along baseboards. Many are adhesive backed. If you use adhesive backed cable mounts we suggest you use the high end products that are available at electrical supply houses. Cable ties are commonly available and can be used to bundle multiple cables into a manageable unit.
