The LinkMaster PRO Tester enables installers,contracto rs and maintenance technicians to map, test and troubleshoot data and voice communication cable and coax runs. Rugged, versatile, and easy-to-use, the LinkMaster PRO tester has mastered the link between performance, simplicity and value for both commercial and residential applications.
OPEN - There is no "OPEN" LED indication. A typical cable may have 2, 3, or 4 pairs. OPENS are displayed as an unlit LED. The user will determine if a pair is present and continuous or OPEN by comparing the illuminated LEDs to the expected number of pairs that should be good. For example, when testing a 4 pair cable, three illuminated LEDs in the PASS area indicate the presence of an OPEN condition in one of the pairs
SHORT - A short circuit condition exists
MISWIRE - Indicates the improper assignment of individual wire pairs to pins for the wiring schemes tested. Tester checks T568A, T568B, 10Base-T, and Token Ring configurations
REVERSAL - Reverse wiring means the pin for one wire in a pair is connected to the opposite pin for the pair in the remote jack
SPLITPAIRS - Split Pairs occur when the tip (positive conductor) and ring (negative conductor) of two twisted pairs are interchanged
Pass Indicators:
T568A and T568B
Four green LEDs on pairs 1-2, 3-6, 4-5, and 7-8. All four pairs are terminated correctly
Token Ring
Two green LEDs on pairs 3-6, and 4-5. Both pairs terminated correctly
10 Base-T
Two green LEDs on pairs 1-2, and 3-6. Both pairs terminated correctly
Shield
Green SHIELD LED indicates the shield on the cable is correctly and continuously wired through the modular plug termination
FAIL Indicators:
A flashing pair LED indicates that this wire pair has a fault. A flashing LED in the FAIL section will indicate which fault was detected. Multiple flashing LEDs indicate multiple pairs and/or multiple faults. Best practice is to correct cable faults until cable is verified as correct with appropriate green LEDs
