5.4.2 - Use of Special Codes $06, Set Filter
Special code $06 is a seven-byte instruction used to establish a filter configuration. It is composed of a command
code ($06) followed by six hex codes that define the filter setup. The parameters to be programmed are listed in
Table 5.4.
Table 5.4 Parameters Programmed with Code $06
Each byte in the $05 sequence performs a part of the setup function. The programming process involves the use of
this special code to setup the sixteen filter configurations in the instrument.
5.4.2.1 - The Code $06 Command Setup
The setup of each byte in the $06 Command Code sequence is:
• Byte 1 is the command code and, therefore, is always $06.
• Byte 2 contains the channel number to be set up, which is defined as one of the following:
• Byte 3 contains the filter configuration number to be set up, which is defined as one of the following:
Table 5.5 Filter Configuration Codes
• Bytes 4 to 7 define the setup of the selected channel number and filter configuration number. These bytes are
mapped out in Table 5.6. Calculation of the correct values for this table is critical to understanding and imple-
menting the remote control process.
