Serial Port (PPP) Details
Physical Connection
Connect a computer to the Master Alarm or Area Alarm Network
Communications Board with an RS-232 cable to the proper connector.
Serial Driver
Windows® typically wants to dial a PPP connection. In our case, we make a
direct connection. The driver, nullmodem.inf, makes a serial connection without
dialing. Install it according to the provided instructions (see “NULL Modem
Driver Setup Instructions for Windows® Operating System” on page 6–20).
Addressing
MedPlus TotalAlert® Alarm Network devices always use IP address 192.168.1.1
with a serial port connection. All of the Web pages that are accessible using the
Ethernet are accessible using the serial port. However, the loading rate is much
slower.
Accessing
Browsers can locate devices in the following two ways:
1. IP address
Example: http://192.168.1.1
2. Local name lookup
Example: http://Master400187
This method works on a LAN if your browser has the “Use NetBios Name
Lookup” option enabled, but will not work across routers to the Internet. The
name used is configured in the Device Setup Web page (see figure 6-10 on page
6–18). The
Device Name,
which is the word
Master
plus its serial number,
always works.
