Electrical Installation
Electrical Connections
All of the electrical connections originate at the back of the analyzer (see Figure
3-15). The analyzer is shipped with all of the electrical connections intact.
There is no assembly or installation required. The four output signal connectors
are screw terminals for two wires per output and polarity is noted below each
set of terminals. The five alarm circuit connectors are screw terminals for alarm
relay contacts which are noted below each set of terminals.
The five selectable alarms provide a set of Form C contacts. The contacts are
capable of switching up to 3 amperes at 115 VAC into a resistive load.
The RS-232 port is configured as data terminal equipment (DTE) and uses a
9-pin D connector wired as follows:
Pin # Signal
1 No connection
2 Transmit Data
3 Receive Data
4 N/C
5 Ground
6 N/C
7 RTS
8 CTS
9 N/C
Connecting the analyzer to a modem requires a PC-to-modem cable. When
connecting the analyzer directly to a PC, terminal or other data terminal
equipment, a “null-modem” cable is required.
Serial interface parameters are as follows:
Defaults
1200 Baud (Fixed)
8 Bits
No Parity
1 Stop Bit
