Interpreting EX2 LEDs

Status LED

The Status LED on the EX2 module operates differently from the status LED on LonTalk devices. Table 25 describes EX2 Status LED activity.

Table 25. Status LED

LED activity

Explanation

 

 

LED is on continuously

Power is on and the unit is operating normally.

 

 

LED blinks twice

The EX2 has not received its configuration from

 

the Tracer MP580/581. Use the Rover service

 

tool to make sure that the Tracer MP580/581 is

 

correctly configured for use with the EX2 mod-

 

ule. Check the I/O bus wiring.

 

 

LED blinks once

The EX2 is not communicating on the I/O bus.

 

Check the communications LEDs described in

 

Table 26 for more information.

 

 

LED is off continuously

Either the power is off or the controller has

 

malfunctioned.

 

 

Communications LEDs

The LEDs labeled TX and RX indicate the communication status of the EX2 module. Table 26 describes the LED activity.

Table 26. Communications LEDs

LED activity

Explanation

 

 

Both LEDs blink regularly

The EX2 is communicating with the Tracer

 

MP580/581 on the I/O bus. (If the LEDs blink nor-

 

mally but the EX2 is not working properly, make

 

sure that I/O bus addresses are not duplicated.)

 

 

Both LEDs are off

The EX2 is not communicating on the I/O bus.

continuously

Either the I/O bus wiring is faulty or the Tracer

 

MP580/581 has not been configured to use the

 

EX2 module. Use the Rover service tool to con-

 

figure the Tracer MP580/581 for use with the

 

EX2 module.

 

 

RX LED blinks,

The EX2 is receiving communications from the

TX LED is off

Tracer MP581 (either for itself or another EX2)

 

but cannot send communications. Either the

 

module is not configured in the Tracer MP580/

 

581 or its I/O bus address is incorrect. Use the

 

Rover service tool to configure the Tracer

 

MP580/581 for use with the EX2 module. Make

 

sure the DIP switches are set for the correct I/O

 

bus address (“Setting the I/O bus addresses” on

 

page 93).

 

 

RX LED is on continuously,

Polarity is reversed on the I/O bus wiring. Swap

TX LED is off

the wires at the plus (+) and minus (–) I/O bus

 

screw terminals on the EX2 module.
