Tip: For details on the types of modems supported,
refer to "PC Issues and Software Installation".
Panel & Software Revisions: VEREX 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).
Once the modem is installed and recognized
under Windows, you need to set a couple of
items through the Control Panel as follows:
Open the Windows
[Start]
menu, and
select
Control Panel
.
Open Phone and Modem Options
(double-click).
In the next screen, select the
Modems
tab.
Select your modem in the list, and click
[Properties]
.
In the
Modem
tab, ensure the "Maximum
Speed" is set to 38400 or higher.
In the
Advanced
tab, enter the following text
as a modem initialization string: ATS7=140.
Tip: Uppercase as shown; 0 = zero.
Purpose: This allows for a longer 'phone number'
(e.g., with pauses, long distance access codes, etc.)
When finished, click
[OK]
as needed to close
the screens.
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 VEREX
Director PC (since the settings are handled by the
Director software and/or Windows operating system).
Panel Modem
xL panels (narrow mainboard) use a plug in
modem module that do not require any special
set up--other than general communications
selections including setting the "Modem Type",
under "Your Account,
Configuration,
System, Communication".
ISM panels (square mainboard) use a built-in
modem/dialler for small accounts, or an
external modem that requires special set-up to
allow it to work correctly with the panel. For
details on wiring and modem set-up, refer to
the Hardware or Commissioning guide for your
panel.
Tip: PDF files for manuals are included on the Director
CD.
Note: External modems pertain to panel-to-PC
communications only. Messages are transmitted to a
