utility. If this ControlWave is a BSAP slave node, and the range of

addresses defined for the BSAP master port end of the

communication line does not encompass the local BSAP address

defined for this ControlWave, BSAP communications will not

function.

 Incorrect EBSAP Group number – if you use expanded BSAP the

EBSAP group number must be correct; if you are not using EBSAP,

the group number must be 0.

If IP communications do not function, it is often due to incorrect IP

addresses or masks. Check to see that the IP address you defined for the

ControlWave is compatible with the range of IP addresses defined for

the communication line on which the unit resides. Also check that the IP

address of the default gateway is correct.

5.3.2 Checking LEDs

The ControlWave GFC Plus includes two red light emitting diodes

(LEDs) that provide operational and diagnostic functions.

You must open the chassis door to view these LEDs.

disabled it - see Table 2-1 in Chapter 2.
