2.3.6
Mechanical Mounting
The STX100-000 is a tray-mounted device and uses a standard 1/4 ATR style tray.
Mount (with counter-sunk screws) onto a clean, grounded surface having a resistance
of less than 0.5 ohms to airframe ground. The STX100-000 may be mounted in any
attitude, but upright (mounting hook at the bottom) is preferred for access and
condensation drainage.
The TX Filter Assembly should be mounted in close proximity to the STX100-000. The TX
Filter is supplied as part of the STX100-IKC install kit, which also includes the base plate
and associated hardware that can be used to provide a convenient method of mounting
the TX Filter. The TX Filter (with base plate attached) is secured with four 10-32 screws.
Installation of the STX100-000, its mounting tray, and the TX Filter should be in
accordance with AC 43.13-1B, chapter 4, section 4, and AC 43.13-2A, chapter 2. Ensure
adequate space is available to allow airflow around the STX100-000 unit.
2.3.7
Data Port
The Data Port allows the user to connect a computer to the STX100-000 to access data
services. There are 2 types of data services handled by the Data Port: Asynchronous,
and Packet Data. For both of these services, the equipment interfacing to the STX100-
000 must be configured for 19200-baud, 8 bits, 1 stop bit, no parity, and hardware
handshaking, with EIA/TIA RS-232 standard signal levels.
Note: The STX100-000 is shipped from NAT in a deactivated state. The unit must be
registered with and activated by Globalstar™ before the following tests can be
conducted. Please refer to the information sheet packaged with the STX100-000
for registration details.
2.3.7.1
Asynchronous Services
Asynchronous Services establishes a data connection between a computer or other
device connected to the data port, and any Hayes compatible modem that is connected
to the Public Switched Telephone Network. The connection between the device and the
remote modem is accomplished by dialing the number of the remote modem from the
AT command line (i.e. ATD18883359533 ). Once the connection is
established between the 2 modems, binary data, or ASCII data can be transmitted.
Sending the "+++" followed by a delay of longer than 1 second, followed by "ATH"
terminates the connection.
2.3.7.2
Packet Services
The data connection is established by the computer issuing a dialing command
"ATD#777". This starts a PPP session using the TCP/IP protocol. Sending the
"+++" followed by a delay of longer than 1 second, followed by "ATH" terminates the
connection.
