Getting started
Before opening the DART 200 box, but preferably before it arrives,
check that the following equipment is available:
• A 12.0 V DC regulated power source with 2.5 amp capability. You
can either provide your own, or order the power source as an option
with the DART 200
• A standard cellular antenna of good quality with a maximum gain of
3 dB. Cable attached magnetic mount antennas are preferred because
the antenna can be positioned easily for optimum signal reception
• A PC with a communications program capable of operating in ASCII
terminal emulation mode. For IBM PC-compatibles this can be
Procomm, Windows Terminal, Hyperterminal, Kermit or something
similar
This makes the PC function as a terminal attached to the modem and
permits the entering of AT commands required for both modem
setup and diagnostics. It is recommended that the program chosen is
capable of logging terminal communications activity to a file for
later analysis or printout in the event that technical support is
required
• A PC communications cable with a male DB9 connector. If your PC
has a DB25 communications port, get a DB25 to DB9 adapter
(available from electronics stores)
Modem setup
To setup the DART 200:
1. Connect the antenna, PC, and power supply to the DART 200 using
appropriate cables and connectors. The red light on the end of the
modem turns on and start blinking at a rate of approximately once
per second (slow blink). If the light does not turn on, check the
power source and connections.
The red OPR light doubles as a signal strength indicator. When the
DART 200 finds a usable CDPD channel the rate of blinking
increases in proportion to the strength of the received signal. This is
discussed in more detail in Channel acquisition, p. 2-10.
