Tip:
For details on the types of modems supported,
refer to "PC Issues and Software Installation".
Note: External modems pertain to panel-to-PC
communications only. Messages are transmitted to a
central monitoring facility through the built in 300 baud
modem and/or an IP connection (
≥
V3.3 panels), or
high-security communications--HSC (via Mark7/DVACS
service in Canada).
Panel & Software Revisions:
Monitor AFx Director
software
≥
V3.2
can connect with panels
≥
V2.0
.
Associated panels must be the same rev. level, and the
Director software must typically be upgraded to the
same level or higher. Exception: V3.3 panels OK with
V3.20 software for this type of connection (i.e., non-IP).
PC Modem Installation or
Connection
Ensure that any PCs to be used for dial-up
panel communications have the required
modem(s) available, or install additional
modem(s) as necessary. Systems with
multiple dial-up panels should generally have
at least two modems available (or more as
needed, depending on the system
communications requirements).
For an external modem (that sits on the PC or
desk), connect to an available serial port using
a standard serial cable (with the appropriate
size 'DB' connector at each 'end').
Notes: A typical cable will be DB9-female to DB25-
male (check your PC and modem to verify your
requirements). Standard modem cables are available
in lengths up to 15 m (50 feet).
Attention:
Do NOT
connect using a "null-modem" cable or "file transfer"
cable. DB9 to DB25 adapters can be used if needed.
(Ensure all 9 pins are connected—some 'mouse'
adapters cannot be used).
Once connected to the computer, the modem
simply plugs into a standard telephone jack
using a telephone extension cable.
Note:
Modems require a direct/analogue telephone
line.
Windows Modem Setup
When a new modem is installed on a Windows
PC, the Windows software will normally detect
the new device, and lead you through some
simple installation steps. An installation CD or
diskette may also be provided with the modem.
If a new modem is not recognized, you can go into the
windows Control Panel and select "
Add New
Hardware
", and follow the prompts that appear.
Note:
Older modems may not meet compatibility
requirements for "Plug-and-Play" installation. In this
case, you may be able to use an installation diskette
provided with the modem (or the modem may need to
be upgraded or replaced).
After installing a modem (or if using one that is
already present), check to ensure that it's
maximum connection speed under MS
Windows is set to "38400" or higher:
•
From the Windows
Start
menu, select
Settings
, and then
Control Panel
.
•
When the 'Control Panel' selections appear,
locate and double-click
Modems
.
•
Select your modem in the list, and click
Properties
.
•
Ensure the "Maximum Speed" is set to
38400 or higher (change this setting if
needed).
•
Ensure "Only Connect at This Speed" is
NOT selected (if present).
•
When finished, click
OK
.
Tip:
Be sure to repeat the preceding steps for any
additional modems (on any applicable PCs).
Note:
The steps described in the next section are
not
required for a modem associated with a
MONITOR AFx Director PC (since the settings are
handled by the Director software and/or Windows
operating system).
