Timeout

Timeout is the length of time your computer will wait for a remote site to answer before it

hangs up.

9.3.2 Setting up the Remote Logger Station

The modem used at the remote logger site needs to be configured to work with data loggers.

The timing of signals generated from

TrendReader Standard 2

must be preserved over the

modem link. High-speed modems have features such as data compression, error correction,

extra buffers and proprietary protocols. These enhance computer-to-computer

communications but interfere with data logger transmission.

9.3.2.1

Software Configuration

Connect the remote modem to your computer (you cannot configure a modem remotely).

Then, set the remote modem's DIP switches to the same settings as the computer station

modem.

To communicate with the modem you will need a terminal program, such as Hyperterminal

availabe in Windows. In Windows, choose

Start >> Accessories >> Hyperterminal

and

then

Hyper Terminal

. When you have chosen the correct COM port:

Type:

AT & F

and press

Enter

. The modem should respond, "OK".

Type the following command string:

AT E

Q1 S

=1 V

and press

Enter

The modem will not respond. This is normal. The modem response mode command

tells

the modem not to respond to instructions. You have now correctly set up the modem for use

at the remote logger station. The individual settings are described below:

Offline commands not echoed

Result codes disabled

Auto Answer enabled (pick up after first ring)

Numeric result codes

Serial port rate follows connection rate

Override CD operation
