SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
eNfusion™ HSD-128 High-speed Data Terminal
(a) Step One: Honeywell System Configuration
Using the Honeywell SATCOM Direct CMT, obtain the antenna loss parameter
and configure the High Rate Data Support settings.
The connection to the Honeywell SATCOM Direct CMT Port uses an RS-232
interface with any “VT-100” terminal emulator program. Configure your VT-100
terminal settings as follows: 9600 bps, no parity, 8 data bits, and 1 stop bit. Refer
to Honeywell provided documentation for more information.
To configure the Honeywell System:
1. Obtain the HPA to Antenna Loss Parameter Value
To maximize system performance, adjust the HPA-to-Antenna Loss
parameter within the HSD system to accommodate the HPA to antenna loss
from the Honeywell SDU.
• Using the Honeywell CMT, obtain the value of the HPA to antenna loss
from the Honeywell SDU.
• Record the HPA to antenna loss value for future reference. Typically, the
value is between 1.5 dB and 2.5 dB. Enter this antenna-loss value into the
HSD system configuration using the HSD transceiver’s Maintenance Port
Utility Program.
2. Configure the High Rate Data Support Settings
Usually, the High Rate Data Support parameters of the Honeywell SDU
(Global Beam, High Rate Data and Spot Beam, High Rate Data) are
configured to “DIS/EN” (disabled/enabled). Although not mandatory, setting
both parameters to “disabled” is recommended.
(b) Step Two: Configuring the HSD Transceiver for HCM Mode
This section describes how to use the HSD Maintenance Port Utility to configure
the HSD system parameters for operation in HCM Mode.
Refer to "Test and Fault Isolation" on page 4-1 for detailed instructions on how
to connect to and use the HSD Maintenance Port Utility Program.
When all the required system parameters have been configured, the HSD must
be “reset” to activate the new configuration. To configure the required system
parameters first establish a connection to the HSD Maintenance Port Utility
program:
• Connect a computer to the maintenance port of the HSD transceiver as
described in
"Test and Fault Isolation" on page 4-1, and then power up the
system.
• Using a terminal emulation program, open the HSD maintenance utility
program.
• Type the password MAINT. (The password does not appear on the screen.)
The HSD Maintenance Port Utility Program menus appear. You are now ready
to begin configuring the system parameters for HCM operation as described in
the following sections.
