Figure 13.2.1 Typical internal wiring
Note: For the sake of clarity, the
Serial Communications and USB op-
tion wiring are not shown.
Note: For 6 or 12 input channel recorders
the transmitter power supply may use either
option board 2 connector or (as shown) the
option board 4 connector.
For 18 input channel instruments, the trans-
mitter power supply must use option board
2 connector, because option board 3 and 4
slots (and associated connector) are occupied
by input board 3 and its cold junction sensor.
