Static IP Addresses
We recommend using static IP addresses for each
Gateway:
●
DL-Windows software performs faster; no wasted
time re-locating Gateways that have had their IP
addresses changed by DHCP
●
Static IP addresses allow operation across subnets
in large corporate networks (such as those that ex-
ist between buildings)
●
Static IP addresses allow Emergency Commands
(such as "Emergency Lockdown") to perform
properly
Contact the Network Administrator
If you know the Gateway will be installed on a large
corporate network that includes multiple subnets, we
recommend you start by contacting the corporate net-
work administrator and request the following:
●
IP Address - An address for each Alarm Lock Gate-
way device
●
Subnet Mask - Filtering data ("mask bits") as re-
quired by the aforementioned IP address
●
Default Gateway - The address of the physical de-
vice, such as a router, for the current subnet to
which DL-Windows will be connected
Subnets
To improve security and processing performance, cor-
porate networks are often divided into interconnected
but separate "subnet" segments. The network admin-
istrator may decide to use routing tables or may speci-
fy blocks of addresses through which the two subnets
can freely communicate in both directions. However,
if the two subnets cannot freely communicate as in the
illustration below, in order to communicate to the
Gateway across the subnet, follow the steps below:
●
Connect the Gateway to local network (DL-
Windows on same subnet); Gateway receives val-
id IP address
●
Using DL-Windows, Discover and add the Gate-
way to an Account
●
Configure Gateway with the static IP address infor-
mation of the subnet you plan to communicate with
●
Disconnect from the local network - remove power
from the Gateway (Gateway will retain static IP
information)
●
Re-connect / re-apply power in the desired loca-
tion / subnet
"
EXPANDER GROUP" DIALS
Inside the Gateway are 2 rotary dials (see Fig. 4).
These dials are used to set the "Expander Group"
when you wish to add
AL-IME2-EXP
Expanders in
your system (all
AL-IME2-EXP
Expanders include an
identical set of dials).
Therefore, the dial values set on
your Gateway MUST then match the dial values set on
your AL-IME2-EXP Expanders. IMPORTANT: Each
Gateway in your system MUST be set to a different
"Expander Group" value along with its associated Ex-
panders. The "Expander Group" dial setting deter-
mines which Expanders are associated with which
Gateway, thus preventing Gateways from discovering
unintended Expanders
. See WI2156 for more infor-
mation about installing
AL-IME2-EXP
Expanders in
your system.
Expander Group values of "
00
" through "
99
" are valid
selections.
IMPORTANT:
The small " selection arrow" on each
dial must be pointing directly to the desired Group val-
ue. In Fig. 5 (below), the Group value is set to "
50
".
Use a small flat-head screwdriver to turn the dials and
make the selections.
Be sure to orient the Gateway
as shown above with the RESET button ABOVE the
dials to ensure proper Group setting!
