CAT Commands
Legend:
Send all commands in REVERSE order from that shown! Commands that duplicate a front panel
button are named with all caps. Parameter variables are named to reflect their format: eg., "CH" indicates
a memory number, from 1 to 64h (1 to 100 decimal).
·- · indicates a padding byte. Value is unimportant, but it must be present to pad the block out to five
bytes.
Opcodes are listed in both hex and decimal format for convenience - only one opcode byte can actually
be sen t.
