During module configuration, the OK LED is red and the APP and BP ACT LEDs

will be on. If the LEDs are latched in this mode for a long period of time, look at

the configuration error words in the configuration request block. The structure of

the block is shown in the following table.

M0 Offset Description Length

0 9000 1

1 Spare 1

2 Port 1 Configuration Errors 1

3 Port 2 Configuration Errors 1

The port configuration error words have the following definitions:

Bit Description Value

0 Type code is not valid. Enter a value from 0 (master)to 1 (slave). 0x0001

1 Protocol parameter is not valid. 0x0002

2 Termination type parameter is not valid. 0x0004

3 Baud rate parameter is not valid. 0x0008

4 Parity parameter is not valid. 0x0010

5 Data bits parameter is not valid. 0x0020

6 Stop bits parameter is not valid. 0x0040

7 Command count parameter is not valid. 0x0080

8 Retry count parameter is not valid. 0x0100

9 Spare 0x0200

10 Spare 0x0400

11 Spare 0x0800

12 Spare 0x1000

13 Spare 0x2000

14 Spare 0x4000

15 Spare 0x8000

Correct any invalid data in the configuration for proper module operation. When

the configuration contains a valid parameter set, all the bits in the configuration

words will be clear. This does not indicate that the configuration is valid for the

user application. Make sure each parameter is set correctly for the specific

application.

If the APP, BP ACT and OK LEDs blink at a rate of every one-second, this

indicates a serious problem with the module. Call ProSoft Technology support to

arrange for repairs.
