Series 5000 Sonar System Operations and Maintenance Manual
Selects the transmitter mask. Each transmitter board is
comprised of 16 transmitters. Each transmitter can be
individually masked. Each bit in the hex value dddd
corresponds to a transmitter. For example $XM0001 would
enable only the first transmitter. Likewise $XMF00F would
enable the upper four and lower four transmitters. The
default is $XMFFFF (all on).
Selects the Sub Bottom Preamp Gain where d = 0 is low and
d = 1 is high. Default is 1.
Enables (d=1) or disabled (d=0) the Sub Bottom Tx. Default
is 1.
Selects the Sub Bottom Tx waveform where d = 0 - 15.
Default is 0.
Selects the Sub Bottom test mode where d = 0 - 6. The test
modes are as follows:
d = 0: Normal mode: RX data is sent.
d = 1: Reserved.
d = 2: Reserved.
d = 3: Generate a sawtooth waveform by holding the low
12 bits at 0xFFF, and incrementing a 12-bit
counter every sample time to drive the high
12 bits.
d = 4: Reserved.
d = 5: Send the static data pattern 1-2-3-A-B-E for every
24-bit sample.
d = 6: Redirect selected TX waveform to uplink.
Decimate the sample rate as required (8:1) and
assign to MS 8 bits of each 24-bit sample. (Low
16 bits 0x0000).
