Comtech EF Data ROSS - Manual (Page 36)

ROSS MN/13070
4.17 Heading Position
This position retrieved from the most recent ACU poll. This value is expressed in decimal
degrees. ROSS polls the ACU for position on a five 5 second interval.
4.18 Handoff Mode
The ROSS Handoff Mode is defaulted to automatic mode (satellite handoff is triggered by vessel
position within Service Areas) on startup. If Force Manual Mode is invoked, Automatic Handoff
mode is disabled. Automatic Handoff mode can also be enabled or disabled. When Automatic
Handoff mode is disabled, the modem will continue to transmit except if it enters a coordinated
area with a transmit flag set to disabled. On power up Automatic Mode is always enabled.
4.19 Stealth Mode
If enabled, ROSS will omit any location information in the Satellite Location Identification
Protocol (SLIP) message. Some modes of operation require location of vessels to remain
unidentified from network operators. This mode can be enabled or disabled from the Operations
menu in the ROSS client console.
4.20 Last Poll
This indicates the last poll time at which the ROSS queried the modem and ACU for status
display updates, approximately every 5 seconds.
4.21 ACU Status
The ACU status is the number of failed or successful poll attempts from start of ROSS server or
from last Reset. A percentage is calculated from the count differences between failed or
succeeded attempts. If failed attempts are equal 100%, check communications between ROSS
and ACU.
Note if status is indicating failed the modulator transmission is muted.
4.22 Modem Status
The modem status is the number of failed or successful poll attempts from start of ROSS server
or from last Reset. A percentage is calculated from the count differences between failed or
succeeded attempts. If failed attempts are equal 100%, check communications between ROSS
and modem.
Note if status is indicating failed the modulator transmission is muted.
