Flow Chart 1: Power Up

What to Expect for Normal Power Up Operation

Upon power up, the Power indicator LED on the front of the TX and the RX illuminates solid red for a
short time while the module is performing power up testing. The solid red LED is normal at power up
and indicates that power up is in process. Once the power up testing is complete, the LED illuminates
solid green. (When a USB cable is connected, the Power LED blinks red while communication is being
established with the PC (see page 67).

Important:

The Power LED can illuminate solid amber at any time, not just at power up. If this

occurs, check the error code (see page 62) and contact technical support (page 64).

Troubleshooting Flow Chart – When Power Up Problems Occur

Start

Apply power to modules.

Does power LED turn from red

to constant green?

No

1

Does power LED

illuminate red?

Yes

Yes

Finished

Power up is successfully

completed.

Check power connections.

*

* Cycle power by

unplugging desktop

power supply from AC

power source and

plugging it back in.

Does

power LED

blink red rapidly

(approx. 5/sec.)?

Does

power LED

remain solid red?

No

No

No

Yes

Yes

Yes

Start over and cycle power.

*

USB is plugged in;

unplug or establish

virtual COM port.

Determine the error code

(page 62) and contact

technical support.

* Cycle power by

unplugging desktop

power supply from

AC power source and

plugging it back in.

If power cycling does

not work, contact

technical support

(page 64).

Note:

Normally on power up, all LEDs

turn on, turn off, and then illuminate in
their operational state.
