If you’re looking to Sell Test-Um JDSU TP300 Resi-Tester Cable Tester

Test-Um TP300 Resi-Tester
The Resi-Tester™ is designed to test all common low voltage cabling systems found in todays automated homes; telephone, network or video. The Resi-Tester™ has a large, bright LCD display and four momentary buttons used to directly access each function. The remote attaches to the main unit for storage and patch cable testing.

The Resi-Tester™ is turned on by pressing any one of the four momentary function buttons and begins testing in the mode for the button pressed telephone (TEL), coax (COAX), network (NTWK) or tone generator (TONE). The corresponding connectors at the top end of the tester are labeled the same as their mode switches. An LCD icon for the currently selected mode will be on or flashing on the screen. To turn the Resi-Tester™ off when in one of the cable test modes, press the button for a different cable test mode, but not the TONE button. Pressing the TONE button will start the tone generator in the Tel Tone, the Coax Tone or Ntwk Tone mode, depending on the current cable test mode.

Upon completion of a telephone or network cable test, the wire map display, ID and any faults are displayed. The top line of numbers on the display represents the connector pins on the main unit. The second line of pin numbers represents the connector pin numbers of the remote, normally being the same as the top line for a one-to-one wired cable. If there is a miswire, the pin numbers on the second line will indicate the pin numbers detected and the “Fail” icon will be on. The icon and the pins involved in the error will flash. If no connection was detected for some of the pins, the first and second line of pin numbers will be blank in those pin locations. If a short is detected, the second line will have a ‘-‘ in those positions along with the “Short” icon being on. If a split pair is detected, those pin positions on the first and second line will be flashing the pin numbers detected from the remote and the “Split” icon will be flashing. If there are multiple errors to display, there will be a combination of the above error displays. The ID icon will have a number directly to the right of it, indicating the remote ID number detected from the remote. A new test is in progress whenever the “Tel” or “Ntwk” icons are on.

In the coax mode, the “Open”, “Short” or “Pass” icon will be on to indicate the results of a test. If the cable passes, the “ID” icon will be on as well as a remote ID number, on the bottom line of the display. The “Coax” icon turns on when a test is in progress.

As mentioned above, the tone generator operates in Telephone, Coax and Network modes. The different modes are provided so that the pins or pairs being driven with a tone signal are displayed in terms of one of the three connectors. The specific mode is selected by pressing one of the cable test buttons (TEL, COAX or NTWK) followed by the TONE button. If the Resi-Tester™ was off when the TONE button is pressed, the last cable test mode used will be selected. The tone generator saves the driven pins for each mode independently. For example, selecting a different pin to drive in network mode will not change the driven pin in coax mode. Pressing any cable test mode button will turn off the Resi-Tester™ when in tone mode.
