Jumper Settings.
There are five jumpers on Option 32/33. Jumper 1 (JMP1) is determined by the clock model;
Jumper 2 (JMP2) determines board operation with JMP3 and JMP4; Jumper 3 (JMP3) determines
board operation with JMP2 and JMP4; JMP2 and JMP3 always move as a pair; Jumper 4 is used
with configuring NTP servers over the RS-232 port; Jumper 5 sets the board for Option 32 or 33.
See jumper settings in Table C.8.
