6 Connecting to External Devices
The analyzer can be interfaced to a variety of external devices via the ports on the rear
panel. Alarm contacts, voltage, and current outputs, and serial communications are
supported. All outputs, analog or digital, are fully isolated from earth ground.
NOTE
During the six minute warm up period at startup, all analog and
digital outputs are held to an artificial 0.011ppb reading to avoid the
reporting of false readings.

Serial Communication Port – J5
Either of two serial communication ports are available at the time of order: RS232C or
RS485 which enable interface between the analyzer and other operating systems.
Up to 32 units may be accessed via RS-485. Operating parameters are 8 bits, no parity,
and one stop bit. Baud rate may be selected from the menu on the display.
See Table 2 and Table 3 for wiring information.
