11. Establishing a Connection with the CV-TAC400
The CV-TAC400 is programmed via a Windows PC, using an USB to RS485 converter for local access
or an optional CV-TAC4M Modem Module for a remote dialup connection.
Remote Connection Using a Modem
Overview
The CV-TAC400 may be connected to a computer system over a telephone line. To do this the CV-
TAC400 requires the modem module. The computer requires a modem connected to it and the SFTD5202
software.
Using the modem is identical to the RS485 connection after the connection has been made. Because a
computer with a modem may be used to manage multiple CV-TAC400's, the "Open Session" initialization is
not used. Downloading and uploading data using the modem is described below in sub-section 11 - 'Open
a Session with the CV-TAC400 (Working Online with a Modem Connection) and sub-section 16, Part B –
'Uploading Saved Information into the CV-TAC400 – Working Online Using the Modem Module'.
The telephone number and password for each building must be entered into the system. When you wish to
update that particular building the dialing information can be selected from that list.
Configuring the SFTD5202 Software for the Modem
Overview
Each time the modem is used the modem must be initialized. Once the modem is initialized it may be
used until the SFTD 5202 software is closed.
Finding the COM Port
To identify the modem to the SFTD5202 software the computer system gives it a name, such as COM3. To
use the modem you must know its COM port number. Determining the COM port varies depending on the
computer's operating system.
Different versions of the operating system will have different methods for determining the COM port. The
following discussion may not exactly match your particular system. In general, for Windows Operating
systems the "Control Panel" will have an icon for modem options. It may be under the "Hardware and
Sound" Icon or directly visible. Selecting it will show which COM port the modem is connected to.
Changing the Settings
a. To change the communications settings follow the steps below:
b. Start the SFT5202 Windows Client Software
c. Select the "Setup" menu. A list of submenus will be displayed
d. Select the "Communications" submenu. The "Communication Setting" form will be displayed
