Modem Connections
Communications to or from the remote-ARM unit can be configured in either of
two ways:
• The internal modem (inside the remote-ARM unit) uses North American call
progress tones.
• External Modem (via RS-232 COM1) used for International locations when
North American call progress tones are not used.
Internal Modem:
(Required parts: cable with RJ-11 male connectors on both
ends)
The internal modem is situated inside the remote-ARM unit. The phone line
connection is connected to the port marked, “Line” in COM1, at the back of remote-
ARM unit.
External Modem:
(Required parts: US Robotics External modem, DB-25 to
RJ-45 converter, cable with RJ-45 male connectors on both ends)
If you choose to use an external modem, use a US Robotics 56K external modem.
If this modem is used, please prepare the modem with the initialization commands
given in the modem preparation section prior to usage. Connect the phone line to
the phone line marking at the rear of the modem. Connect the DB-25 to RJ-45
converter at the rear of the modem, and run the other end of the RJ-45 cable to the
RS-232 COM1 port at the rear of the remote-ARM unit. Verify that you are using
a remote-ARM unit that does not have an internal modem (part number ARM2000-
RU-EXT).
Testing Communications Between PCARM and Remote-ARM Unit
To test communications between the two modems, the PCARM software needs to
be running. (Install the software and configure it, if not done.)
1
Turn on the PC and wait for Windows 95 to load.
2
Click the PCARM.exe shortcut icon to run the PCARM program.
This puts you at the System View screen.
3
On the System View screen, click the device with which you want to
communicate.
This puts you at the Device View screen. To find the device, place the mouse
pointer over the cell for the device.
4
On the Device View screen, click Test to test communications between the
PCARM and the remote-ARM unit.
An alarm condition prompts the remote-ARM unit to dial the PCARM (alternate
method of test).
