The serial connector is used for computer, printer and
modem communications:
Figure 1- 4
The serial connector is an 8 pin mini DIN
connector (AppleTalk
TM
compatible pinout).
1 - Flow control output (RS-232C levels)
2 - Flow control input (RS-232C levels)
3 - Transmit data negative output (RS-232C levels)
4 - Ground
5 - Receive data negative input (RS-422)
6 - Transmit data positive output (RS-422)
7 - Control input (RS-232C levels)
8 - Receive data positive input (RS-422)
Both outputs have a 600 ohm series
resistance.
The AC/DC output connector is used to output the signal
from the System 824 microphone to external devices such as
DAT recorders, real-time analyzers, other sound/vibration
measurement equipment, voltmeters, chart recorders, etc.
NOTE: See chapter 5 for more details
concerning the AC/DC outputs.
