8.7 Testing & Troubleshooting
The T-Link TL250/TL300 and the System III Receiver can be connected directly with an
Ethernet crossover cable. An Ethernet crossover cable can be made by taking a standard
Ethernet cable (which will have wires attached to pins 1, 2, 3 and 6 only on the 8 pin RJ-45
connector) and swapping pin 1 with pin 3, and also swapping pin 2 with pin 6, on one end of
the cable only. This effectively reverses the transmit and receive pairs, and allows two hosts
to communicate without the use of a network hub.
Upon T-Link power-up (without the Ethernet cable connected), LED2 will blink periodi-
cally, approximately once every 12 seconds. This represents the T-Link TL250 attempting to
send a connection request to the receiver. The TL250 will try to connect to the receiver until
it succeeds.
The Activity and Link LED's are normally OFF in their default state after power-up (i.e.
when no Ethernet cable is connected, and there are no packets being transmitted or received,
respectively). Refer to the Status Indicator table above for details.
Blinks/
Priority
The Ethernet link between the transmitter and local
1 hub or router is absent. This is equivalent to the link
LED on the Ethernet chip being off.
The transmitter account code is still set to the
2
default value of FFFFFF.
The transmitter is not receiving Receiver Heartbeat
3
commands from the receiver.
The transmitter is not receiving polls from the DSC
4020, 5020 or DVACS panel through the PC-Link
4
interface. Generic panels are not supervised by the
transmitter.
There are inputs on the T-Link which are in 'alarm'
