When the Switch Data command is accepted, the 853 responds with a 256 byte IKX Return Data packet or an 18 byte ILX Return Data packet. A message type of IKX must be selected to change any of the programmable settings.

Page 5: Operation
65536. New for version 1.02: 853 Echo Sounders are now available with the standard frequency of 120kHz or with an optional frequency of 300kHz. Byte 11 of the 'IKX' Echo Sounder Return Data packet reflects the configured frequency (0=120kHz, 1=300kHz). - Page 6 A timestamp has been added to the ping header. The date and time must be sent to the unit using the appropriate fields in the Switch Data Command. The 853 will keep track of the time until the next command. Each ping header in the file will contain a unique time.
- Page 7 16JUL15 SWITCH DATA COMMAND The 853 accepts up to 27 bytes of switch data from the serial interface and must see the switch data header (2 bytes: 0xFE and 0x44 HEX) in order to process the switches. The unit will stop accepting switch data when it sees the termination byte (0xFD HEX). The termination byte must be present to process the switches.

Page 11: Return Data
16JUL15 RETURN DATA After a Switch Data Command, the 853 replies with a serial return data packet. The packet size depends on the value of “Message Type” (Byte 8 of the Switch Data Command). The standard return (Message Type = 0) is a 256 byte “IKX” packet consisting of a 55 byte header, 200 range bins of echo data and a termination byte value of 0xFC. - Page 12 [(Byte 7 & 0x7F)<<7] | (Byte 8 & 0x7F) Byte 9 Range 0 = 25 Meters 1 = 50 Meters 2 = 100 Meters Byte 10 Gain 1 = 20dB 2 = 40dB Model 853 Serial Interface Specification Page 9 of 13...
