Note the following cabling information for this wiring guide:
• Only two pairs of wires are used in the 8-pin RJ-45 connector to carry Ethernet signals.
• Even though pins 4, 5, 7 and 8 are not used, it is mandatory that they be present in the cable.
• 10BaseT and 100BaseT use the same pins; a crossover cable made for one will also work with
the other.
• Pairs may be solid colours and not have a stripe.
• Category 5 cable must use Category 5 rated connectors.
Devices on the Ethernet network continually monitor the receive data path for activity as a means of
checking that the link is working correctly. When the network is idle, the devices also send a link test
signal to one another to verify link integrity.
10/100: This Amber LED is ON when a 100Base-TX link is last detected. The LED is OFF
when a 10Base-T link is last detected (the LINK LED is ON). Upon power-up the
LED is OFF as the last detected rate is not known and therefore defaults to the
10Base-T state until rate detection is completed.
LN/ACT: This dual purpose Green LED indicates that the control panel has established a
valid linkage to its hub, and whether the control panel is sending or receiving data.
This LED will be ON when the control panel has established a good link to its
supporting hub. This gives you a good indication that the segment is wired
correctly. The LED will BLINK when the control panel is sending or receiving data.
The LED will be OFF if there is no valid connection.
The control panels require a specific IP Address and Q-Link ID. The IP Address and Q-Link ID can either
be set using the front panel “setup” menus or using the DEBUG serial port on the rear of the unit.
The control panels can be upgraded using either serial or ftp. Both options are available through the
DEBUG serial port. The serial configuration options can be configured by connecting a straight-through
D9 serial cable to the DEBUG serial port and using a third party tool like Hyperterminal or TeraTerm with
serial settings 115200, 8, None, 2, None.
Please note that Qlink Mode can’t be used with the 3025EMC. Only ETHERNET Mode
can be used.
Please note that the front panel setup will only be available while the control panel is
“Offline”, i.e. while the 3025EMC is NOT currently communicating with the control
panel.
