The standard for the ES data output signals is 5 VAC when a 38, 70, or 120
kHz ES is installed, and is 12 VAC when another board is installed.
The ES data output from pins 3/4 are the data from the board installed in board
slot No. 1 of the model SR-87 transducer. The ES data output pins 5/6 are the
data from the board installed in board slot No. 2 of the model SR-87
transducer.
* The signals from the model SR-87 transducer in the case of 38, 70, or
120 kHz are output only from pin Nos. 3/4.
* In the case where the TX output from the board mounted in the No. 1
board slot in the model SR-87 transducer is set to OFF (refer to Section
3-2-3), ES trigger signals are not output, and there is no data output
from board slot No. 2, so set the transducer to ON when using the
system.
