E-FSA Panel to Laptop Connections

E-FSA Panel to Laptop Connections
There are three different option modules available for the E-FSA series of small analog
panels. Each allows for communications between the panels and a laptop computer
running the FSA-CU configuration utility program. You must have one of these three to
be able to communicate to an E-FSA panel with a computer. The modules are not
included with a panel and must be ordered separately.
1. The SA-232 provides an RS-232 interface to the panel. The SA-232 has a four
position terminal block, and requires a download cable with a DB9 female
connector. This DB9 connects directly to a DB9 male connector on a laptop. For
those computers without a serial port, a USB to RS232 serial port adapter is
required (purchased locally). The Edwards part number for the download cable
is 260097, or you can make your own.
To build your own download cable, refer to the picture of
DB9 connector to the right and pin designations below.
Pins on DB9 are numbered looking at the female side
facing you.

The SA-232 card is small pc board measuring approximately 2” wide x 1” high.
In lieu of ordering one card for every panel, consider making up a “portable”
download assembly for each technician. Connect the wire leads of the download

cable to the SA-232 terminal block, and use heat-shrink tubing or a small plastic
case available from a local electronics store to protect the assembly, leaving the
small ribbon cable accessible. Connect the ribbon cable to the main board to
download to the panel, then take it with you when you’re done. Be careful when
unplugging the ribbon cable from the panel. The panel does not have to be powered
down, but the physical connection is delicate.
Since most computers today do not come with a serial port, you will probably need a
USB to RS232 Serial port adapter (not supplied by Edwards). Be sure the adaptor
works with the particular laptop and operating system being used. Also pay
particular attention the first time the adaptor is plugged into the laptop to make sure
the drivers install properly.
You will need to know which COM port is configured when the adaptor is installed.
To find out, open Device Manager and look for the USB-to-Serial Comm Port as
shown below. This will be needed when you select the COM port to use in the FSACU Configuration Utility Communications tab.
Be sure the COM port number assigned to the USB adaptor is between 1 and 8. If
higher than 8, you will need to reassign it a new number. You can do this by right
clicking on the port, then select Properties > Port Settings > Advanced > COM Port
2. The SA-DACT dialer module can be used as a modem to provide
communications to the control panel over a telephone line system. Phone line
connections must be available for the SA-DACT and laptop computer.
3. The SA-ETH provides an Ethernet network connection. This connection can also
be used as a direct connection from a laptop to the control panel. A standard
network cable (crossover type not required) is all that’s needed from your laptop

to the SA-ETH card. See below for computer network connection settings for
both Windows XP and Windows 7 operating systems.
From your Windows XP Start menu, go to Settings, Network Connections.
Double click on Local Area Connection.
Stay on the General tab, click Properties.
3|P a g e
Scroll down to Internet Protocol (TCP/IP) option. Highlight it, and click on Properties.
Select the “Use the following IP address” option.
Note: If the pc already has an IP address listed in the field, copy it down so that the
address can changed back to that setting once panel programming is complete.
4|P a g e
The SA-ETH card defaults to IP address
Enter an IP address that is different from that by one or two places (or different from
whatever the panel’s IP address is if it’s been changed).
Then hit Tab, and Subnet mask will fill in as shown.
Hit OK. You can now connect a network cable between your laptop and SA-ETH card
to communicate with the panel.
5|P a g e
If your laptop has Windows 7 operating system, go to Control Panel from your Start
Click on the Network and Sharing Center icon.
Select the Change adapter settings option on the upper left hand side of the screen.
This will display the available network connections on your laptop. Highlight the Local
Area Connection option, right click on it and select the Properties option.
6|P a g e
Highlight the Internet Protocol Version 4 (TCP/IPv4) option and click on Properties.
Then follow the same steps to set the IP address as described earlier for Windows XP.
