Verify that the network cable between the LAN Controller Card and the hub is in
good condition.
Verifying Settings
via HyperTerminal
Use the setup procedure described previously in "Configuring the LAN Controller”
to check the LAN Controller’s IP settings for incorrect values. Make corrections, if
necessary. For example, if a LAN Controller Card has been moved from one office to
another, the IP address information will need to be reconfigured for the new office.
Note: When examining the IP settings, you need to be on site with the 289H monitor
so that you can set the LAN Controller Card dipswitches to the Configure Mode
(Figure 3) before re-entering the desired information. You will also need to make the
serial connection between the LAN Controller and a PC that has the HyperTerminal
program (see Step 3 of the procedures for Configuring the LAN Controller). Once
the IP settings have been verified and/or changed, remember to reset the LAN Con-
troller Card dipswitches to the Server Mode (Figure 4).
When reconfiguring the IP settings, verify your network cable connection as de-
scribed previously in “Network Hardware Connections.”

Appendix A –
Network Information for LAN Controller Operation
The LAN Controller Card uses 10 Mbps Ethernet. The network hub or Ethernet
adapter to which the LAN Controller is connected must be either a 10 Mbps unit or a
10/100 unit that can adapt to either 10 or 100 Mbps.
The LAN Controller normally works in “server” or listen mode. In server mode, a
289H with a LAN Controller Card receives calls from PressureMAP. When the 289H
sends an alert to the PMAP system, the LAN Controller switches to “client” or call
mode. During alerting, the PMAP system becomes the “server.”
For the LAN Controller to work properly on a telephone company network, all net-
work firewalls must be configured to allow PMAP calls to the 289H with the LAN
Controller Card. For alerting to work properly, network firewalls must also be con-
figured to allow the 289H with the LAN Controller Card to call the PMAP system.
To help the network administrator configure the network to allow two-way commu-
nications between the LAN Controller and PressureMAP, please fill out the follow-
ing two-part worksheet and give it to the network administrator.
