Gigabit inline PoE

tester and detector

2

• 2 independent Volt and Ammeters for all PoE methods. For measuring 802.3af, 802.3at, passive and also DC power supplies.

• Mode A and Mode B displays o Mode A displays the voltage on pins 12 and

36, also displays DC voltages o Mode B displays the voltage on pins 45 and

78

• 568A or 568B Inputs for Mode A o RJ45 LEDs on each input RJ45 detect

polarity - o If ON or Pulsing – change to the other

input RJ45 connector

o 568A expects 12+ and 36- o 569B expects 12- and 36+ o Load side is always 568B ( 12- 36+ )

• Switch to Active mode to detect 802.3af

3

• 802.3af on / off – set to ON o Emulates an 802.3af device in class 3 to

detect a PoE switch, will cause a PoE switch to send power even if no device is

connected. Voltage will be displayed, internal load is 300 mw.

o Will power a non-PoE device from a PoE switch.

o Disables mode A ground return unless an 802.3af switch is detected for passive tests

• 802.3af on / off – set to OFF No display until voltage is present – does not change the class of the attached device.

Display is active once voltage is presented by

either a PoE switch or a passive PoE injector. Connect an 802.3af or 802.3at load to initiate power from a PoE switch. Passive PoE is always on.

4

• 4 Display Modes o Display A – shows the status of pins 1,2

and 3,6 from the RJ45 In to RJ45 Out o Display B - shows the status of pins 4,5

and 7,8 from the RJ45 In to RJ45 Out o Display A also shows the status from the

2.1mm DC plug In to DC plug Out o Display B and A can operate at the same

time with different supplies in full isolation

• Voltage Range – 1% accuracy o Mode A – 20 to 56 volts o Mode B – 20 to 56 volts o DC connector – 6 to 56volts

• Amps measured o Mode A and Mode B – 0 to 500 ma

2% accuracy above 5 ma o DC connector – 0 to 5 amps

2% accuracy above 50 ma

5

• Fuse protection The RJ45 inputs are protected by a self resetting 500ma fuse on each of the Mode A and Mode B power pairs ( 12/36 and 45/78)

• Expected Polarity on this device o 568A expects + voltage on 12, - on 36 o 568B expects + voltage on 36, - on 12 o Mode B expects + on 45, - on 78 o The DC socket expects center + o Reverse voltage does not harm the poe

Tester o RJ45 LEDs pulse if voltage is reversed

• Battery Free operation

o The Tester requires just 4 ma for operation, taking power from the PoE source

6

• Data compatibility: o 10/100 and gigabit data rates are

supported in all modes o Data passes without modification thru the

tester o An RF transformer separates the power data

data from all 4 pairs on the input, and re-inserts power onto data at the output

o Measure power without interruption of data.

o Works with managed or unmanaged Ethernet switches, or injectors

o Works with midspan or endspan PoE systems.

Connect the the PoE tester Source side to your

Switch or Injector. Try the 568A or 568B inputs to see which works for you. Or use the included 2.1mm jumper cable for DC power supply testing

Every 3 seconds the display cycles to a different parameter. The top display is the Mode A and DC input display, the bottom display is the Mode B

display. Mode B and A (or DC) can operate at the same time.

802.3af Mode B vs Mode A

Mode B uses pins 4,5 for + voltage and 7,8 for return

Mode A uses pins

1,2 and 3,6 for power and Data, either polarity is allowed since EIA

568A and 568B are mixed in the real world.

568A and 568B inputs are provided for Mode A operation. Note in the diagram above, that pairs 1,2 and 3,6 can be swapped – and both are

legitimate Ethernet connection methods. Therefore, somewhere in the wiring between the PoE source and load, the polarity of power on 1,2 and 3,6 could be reversed.

12

568A/B inputs have no impact on mode B power – but if the reverse polarity mode A Yellow LED lights up – then unplug and test using the other input on your PoE Tester.

568B output - The PoE Tester load side is 568B – pins 1,2 are minus and 3,6 are plus.

Passive PoE - If the source is passive PoE – then

the voltage will be displayed with or without load. Mode B PoE - Power and data will be passed thru

to the LOAD side of the tester. Use either the 568A or 568B input for Mode B. The Volts will be displayed. Once current is flowing, Amps and Power will be displayed.

Cambium/Canopy – these are mode B reverse polarity – use our WS-CS-RJ45 (x2). If Mode B power is reversed, then a Yellow LED will light.

13

802.3af Pass-Thru Mode – Set the 802.3af switch to OFF. If the source is an 802.3af or 802.3at switch, then there will be no indication until a compatible load device is connected.

Connect your PoE switch to either the 568A or 568B input. If you see a pulsing yellow light – then move the source to other input. Once a 802.3af or 802.3at device is connected, the

display will start to show Volts, Amps, Watts.

802.3af Simulate Mode - Set the 802.3af switch to ON. If the source is an 802.3af switch, then the

display will be active even without a load. Connect your PoE switch to either the 568A or 568B input. If you see a pulsing blue light – then move the source to other input. Once any load is

connected, the display will start to show Volts,

Amps, Watts. Note, this operation enables a non-PoE device to receive power from a PoE switch.

14

802.3at - An 802.3at compatible PoE switch may provide power on all 4 pairs of the Ethernet cable – in this case – both displays will activate – and the power will be the total of the two displayed

values.

Once power is flowing to the device, the PoE tester will display the Volts (U) the Amps (A) and Volts * Amps as Power (P). The current is

measured on the ground return from the load RJ45 to the source RJ45 connector, or from DC out to DC in.

DC connector – A power supply can be tested with this device. Connect the 2.1mm Source connector to the PoE tester, the voltage will be displayed. Connect the load side to the device to

be powered, the results will be displayed on the

Mode A display.

15

Note – it is possible to use the DC connector and Mode B at the same time. 2.1mm jumper - an 7.5 inch 2.1mm jumper is

included for testing DC power supplies from 6 to 56 volts. USB voltage Tester – please see our 5v USB

inline tester for 5 volt USB applications.

Operation with WiFi-Texas dual power supply Injectors: Like WS-GPOE-12-1U or WS-POES-8-7.

o If only mode A power is provided, compare the current flowing into the DC connector with the total load, since some current might bypass the A mode sensor and flow undisplayed via the B mode path.

o If only mode B power is provided, set the

802.3af switch to “ON” - this will direct all

current into the Mode B signal path.

o If both A and B power is provided, add the A and P values together to record the total.

Normally, all current will be directed to the

A mode return path.
