Chapter 5 Connecting to an ISP
Configuring Captive ISP on the JACE-4/5
Niagara Release 2.3
Niagara Networking & Connectivity Guide Revised: May 22, 2002
5–11
General Properties
remoteAddr any valid IPv4 address in
dotted decimal notation
192.168.1.111
The IP address of the remote machine you are dialing into.
For most ISPs you do not need to specify this parameter. You
should remove the default value (remoteAddr= ) or comment out
the line (#remoteAddr=192.168.1.111) so the JACE accepts
whatever address the ISP assigns.
localAddr
Note: In release
2.2, this parameter
is not listed in the
file. In release 2.3, it
is listed but disabled
by the preceding #
sign. To enable the
parameter, remove
the # and supply a
valid IP address.
any valid IPv4 address in
dotted decimal notation
disabled
Specifies the IP address of the dial-in interface on the JACE. If the
ISP requires the JACE to request a specific static IP address, you
must specify it using this parameter. When this parameter is absent
(or left blank), the JACE accepts whatever dynamic IP address is
assigned by the ISP.
Release 2.2 and earlier—If you specify an address for this
parameter that does not match what the ISP assigns to the JACE,
the JACE will not connect to the ISP.
Release 2.3—If you specify an address for this parameter that
does not match what the ISP assigns to the JACE, the JACE will
ignore your setting and use the address the ISP assigns.
Modem Configuration Properties
device COM1
COM2
The COM port used by the modem. If using the JACE-4 internal
modem, this should remain at COM2. If using an external modem
with the JACE-4, this should match the serial port assignment of
the RS-232 port as listed in the port.properties file (see “Enabling
the JACE-4 Modem (Internal or External),” page 4-10).
baudrate
57600
48800
36600
19200
The initial baud rate to use between the JACE and the modem. In
most cases you will not have to change this parameter.
initString depends on modem
• JACE-5—AT&F1E0X4
(USR Sportster)
• JACE-4—ATE0Q0V1X4&D
2&K3\N3%C2&C1&Q5W2
(internal Cermetek)
The modem-specific initialization string sent to the modem when
the JACE boots. It sets options required by our hardware (see the
“About Pre-configured Modems” section on page 4-7).
Initialization string for the Zoom External V.90 Dualmode
Faxmodem— AT&FE0S0=0
updateNvRamCmd depends on modem
AT&W0 (USR Sportster)
Modem specific command used to save the initialization string to O
so it is available to initialize the modem if the modem reboots and
the JACE does not.
updateNvRamFlag
false
true
Set to true to save the initialization string to NVRAM during the next
boot. This flag must be manually set to true each time initString is
changed. The JACE will automatically set this back to false after
the NVRAM has been successfully updated. This prevents
unnecessary writes to modem NVRAM.
initFailLogOnly
Note: Supported in
release 2.3 or later.
false
true
When set to false, the JACE will reboot up to three times in order to
initialize the modem if it does not respond on the first boot. If the
modem is not initialized by the third time, a message is sent to the
Admin Tool’s event log. When set to true, the JACE will not reboot
if the modem doesn’t initialize, but will only send a message to the
event log.
