Progam Cascade Modem to Work with ECM Hestia equipment

By default the Cascade modem version 3 is set from the factory to work with Diamond equipment and can be used with some other standard equipment without programming. With the ECM Hestia unit the Cascade modem needs to be programmed to interface correctly and hold the correct settings. This is done with the standard AT command set and the modem will store these commands when programmed properly. The steps below show how to program a Cascade modem using a terminal program to work with the Hestia device.

Step #1:
Open a terminal program such as Hyperterminal and set the COM port settings to a baud rate of 19200, 8N1.

Step #2:
Power on the Cascade Modem and plug the serial cable into the modem and your computer making sure you are on the correct COM port.

Step #3:
Connect to the cascade modem by clicking the dial icon or start connection depending on the terminal program you are using.

Step #4:
Type "AT" then the ENTER key in the terminal to establish a communication line to the modem. The modem should return either a "0" or an "OK" as a response. If there is no response than a proper connection has not been established unless the modem has been previously set to not respond (in case of the modem set to not respond type "ATV1" then ENTER to set the modem to provide a “OK” response to AT commands).

Step #5:
Once the Modem connection has been tested you will need to send the following command strings to the modem (it is important to send these commands in this order as the order in which the commands are set does matter).

Send: "AT&F+GCI=B5" (press ENTER - Modem will return "0" or "OK")
Send: "ATX4&D0&K0S0=3S7=60S10=7S11=70$SB9600&E12Q1V0E0" (press ENTER - modem will not return an OK as it programmed not too after this string)
Send: "AT&Y0&W0" (press ENTER - This will store the current setting into memory)

Step #6:
To verify the modem was properly programmed type in "AT&V" then the Enter key to have the modem print out the current settings which should match the following.
