computer typically located in the ED. It will listen on two internal ports for connections
from the Gateway.
The Gateway Client may be installed on multiple computers such as the Gateway server
and any other computers on the network that have access to the Gateway server.

While this will not be a typical installation, it is possible to install the Monitoring Station
and Gateway on the same computer. This offers no advantage for network isolation, but it
does enable the Gateway Client to be used to monitor network transmissions.

In this configuration, the system will be a dedicated computer typically located in the ED
on an isolated network such as a dedicated high speed internet connection or in the DMZ.
The Gateway will run as a windows service. To receive 12-lead data from the PDAs the
gateway requires a fixed IP address and two port assignments. This fixed IP address must
be accessible to eSync on PDAs as a public address on the internet or through a VPN. If
network address translation (NAT) is used the address may be assigned to a router rather
than directly to the gateway. This is the same IP address that is then entered in the Server
Address field when adding the Server to the eSync application’s Server list (see
“SmartLink Wireless Monitoring Station installation” on page 8). When installing the
SmartLink Wireless software, ensure that the IP address and ports are not blocked by any
firewall. Contact your Network Administrator concerning this subject.
The Gateway Client may be installed on multiple computers such the Gateway/Monitoring
Station system and any other computers on that have access to the Gateway.
