mode. It operates at 300/1200/2400 baud. This modem has
speech and tone capabilities and comes with a connect cable to
attach to the telephone line.
Note
The modem is disabled when an interrogator cable is con-
nected to the flow meter’s interrogator port. It cannot receive
incoming calls, and the alarm dialout will be rendered inopera-
ble, while this cable is connected. Disconnect the interroga-
tor cable in order to use the 4200T Modem.
4.2.2 Modem and
FLOWLINK Software
The 4200T Modem communicates with Isco's FLOWLINK data
storage and acquisition software, setting up the flow meter to
collect blocks of data. FLOWLINK allows storage and interpre-
tation of flow meter data. Other FLOWLINK software packages
can write reports with this collected data.
4.2.3 Connection to a Line The FCC (Federal Communications Commission) governs com-
munications over telephone lines. Your local telephone company
will provide you with the line between the flow meter and the
computer. Call them for connection information. The FCC
requires the following information be published for connecting the
modem to the phone line:
“This equipment complies with part 68 of the FCC
rules. On the case of this equipment is a label that
contains, among other information, the FCC regis-
tration number and ringer equivalence number for
this equipment. If requested, this information must
be provided to the telephone company.”
“This equipment uses the following USOC jacks:
USOC RJ11C.
“The REN is used to determine the quantity of
devices that may be connected to the telephone line.
Excessive REN's on the telephone line may result in
the devices not ringing in response to an incoming
call. In most, but not all areas, the sum of REN's
should not exceed five (5.0). To be certain of the
number of devices that may be connected to the line,
as determined by the total REN's, contact the tele-
phone company to determine the maximum REN for
the calling area.
“If this equipment causes harm to the telephone net-
work, the telephone company will notify you in
advance that temporary discontinuance of service
may be required. If advance notice isn't practical,
the telephone company will notify the customer as
soon as possible. Also, you will be advised of your
right to file a complaint with the FCC if you believe
it is necessary.
“The telephone company may make changes in its
facilities, equipment, operations, or procedures that
