pattern to avoid searching out far enough to be attracted by and tracking onto a nearby (adjacent)
satellite. If you wish to change this parameter, key in the desired value and press ENTER.
5.3.9. SEARCH DELAY
Sets the time-out for automatic initiation of a search operation when the signal level (AGC) drops
below threshold. Units are in seconds. Range is 0-255 seconds. Default setting is 30 seconds. A
setting of 0 disables the automatic search initiation. If you wish to change this parameter, key in
the desired value and press ENTER.
5.3.10. SWEEP INC
This parameter should be set for the desired azimuth sweep speed of a No Gyro search or the
Sweep Increment dimension of an Inclined Orbit search (refer to the search pattern information in
paragraph 2.7).
When the GYRO TYPE parameter is 0000 the ACU is in “No Gyro” mode (no heading input is
available for the ACU). A SWEEP INC setting of 0040 = 9 degrees/second, 0060 = 13
degrees/second or 0080 = 18 degrees/second. Larger antennas should have slower speeds and
smaller antennas should have faster speeds. Refer to your antenna manual for factory default
setting for your antenna. If Gyro Type is set to 0000, you must set SWEEP INC correctly and
SATELLITE REFERENCE MODE
MUST also be turned ON .
If you want the ACU to conduct an Inclined Orbit search pattern you must set SWEEP INC to 192 if
your antenna is a Series 04 or Series 06. Set to 193 if your antenna is a Series 97, Series 00 or
Series 07. This parameter sets the sweep increment dimension of the search pattern.
5.3.11. SYSTEM TYPE
Selects system options according to the following table. Add together all the desired options to
determine the proper entry. Refer to your Antenna Pedestal manual for the correct default setting
for your antenna. If you wish to change this parameter, key in the desired value (the sum of the
desired functions) and press ENTER.
128 Reverse External Modem Lock input polarity (logic hi = lock)
64 Enables LNB voltage output
32 Display Relative in the Azimuth entry display
16 Reverse blockage output logic (SW2 logic hi = blocked)
8 -- Reserved --
4 Auto SAT load after SEARCH failure
2 Enable External Modem Lock Input (logic low = lock)
1 Auto SAT load on “hot” RESET and ACU Power-Up
5.3.12. GYRO TYPE
Selects the type of gyro compass interface for ship turning compensation. 2 indicates S-B-S, or
NMEA, gyro interface. 1 to 360 indicates a 1:1, 36:1, 90:1 or 360:1 Synchro gyro interface. 362
indicates 360:1 synchro using 12bit S/D interface. If you wish to change this parameter, key in the
desired value and press ENTER.
362 for 360:1 Synchro with S/D Converter
360 for 360:1 Synchro with SBS Converter
90 for 90:1 Synchro with S/D Converter
36 for 36:1 Synchro with S/D Converter
2 for Step-By-Step gyro or NMEA gyro
1 for 1:1 Synchro with S/D Converter
0 for No Gyro linear AZ Search Mode (No Heading input
available)
