B.1.9 INITIALIZATION MESSAGE

If datapoints A188 and A189 are configured to NON-NULL values, their contents will be transmitted
onto the Datalink network at reset/power-up. Prior to transmitting, a delay based on the unit’s in-
strument address is observed. There is a one second delay between the transmission of datapoint
A188 and datapoint A189 contents. Datapoints A188 and A189 can be configured as two NULL
TERMINATED strings up to 10 characters each. For example, to initialize a Hayes compatible mo-
dem to Auto Answer, datapoint A188 would be configured through the faceplate push buttons to ap-
pear as follows:

A188

L

ATS0=4

C

R

This 7 character string is an Auto Answer command that directs the modem to respond to calls on
the fourth ring. It is an

AT command that loads the modem S0 register with a 4 to indicate a mo-

dem response on the fourth ring. Any value other than

0 in this modem register activates Auto An-

swer. The NULL TERMINATING values are automatically propagated into the remainder of the
datapoint field by the controller. Datapoint A189 can be left at all NULL VALUES for this operation.
