For optimum communications performance with your Analog landline to the CDS-
9022 in Analog Mode, you should be using a CONEXANT/ROCKWELL HOST
modem chipset, or other cellular ready modem. For further information, see the
suggested modem list at www.dataremote.com, in the products, landline modem
section.

Do not change these commands, and assure that your DTE device does not initialize
the modem with different values for this AT-COMMAND. If your DTE device
requires additions to the above modem initialization string, please call our Technical
Support line for help.
We can provide you with customized firmware which offers options that our standard
object code does not offer, such as; DTR ALWAYS ON, DISPLAY MODIFY
RESULT CODES, PASSWORD, or only accept certain Caller ID #’s by checking
with a lookup table database of allowed incoming phone #’s before answering,
callback numbers, and various other applications.
Saving AT-strings into the CDS-9022A Analog modem via a host terminal,
laptop, etc.
Use any type of recommended terminal program and set the Terminal to N,8,1, NO
FLOW CONTROL. Default DCE speed = 19,200pbs. If you have changed the DCE
speed in the Config Menu make sure you use that
DCE speed.
TYPE:
*ATI3 <enter>
Modem will echo
V3.500-V34_2M_DLP
OK
This echo verifies that you’ve selected the Analog modem. This Command is for
modifying the CDS-9022A’s Default modem string.
NOTE: Some Terminal programs will not echo back the * character. The CDS will
still see it. LED D6 will also indicate that the Analog modem is selected.
