概览
The BDR320 had an SDI-12 interface, 2 differential (4 single-ended) analog input channels, 1 switched excitation output, 4 digital control outputs (one continuous), and 2 pulse count channels. Internal memory stored up to 30,000 data points. Data file format was NOT compatible with the CR500, CR10(X), 21X(L), or CR23X dataloggers.

A fully-equipped BDR320 system included a data logger module and wiring panel, an enclosure (ENC10/12 or ENC12/14), a power supply (alkaline or rechargeable), PC300 BDR Support Software (3.5" diskette), a DB-25F RS-232 interface (7026 or SC25PS serial cable required, ordered separately), and a DB-9F modem connector.

Power Supplies
Options were either the BPALK Alkaline Battery Pack or the PS12LA Sealed Rechargeable Power Supply. Refer to Ordering Info for information about the BPALK. The PS12LA has been replaced by the PS100 and is no longer available.
Note: BDR320s sold before 1996 had a PS12ALK Alkaline Power Supply instead of the BPALK.
AC Rejection
The BDR320 had a couple of AC rejection options that are no longer available. They were:
- 6661 Standard 60 Hz AC Rejection—integrated analog voltage measurements over one 60 Hz cycle which eliminates the effect of 60 Hz ac-induced noise on the measurement.
- 7600 50 Hz AC Rejection—integrated measurement based on 50 Hz cycle instead of standard 60 Hz rejection (for countries with 50 Hz ac power).
Software
All of the software used with the BDR320 is no longer available. PC208 DOS Datalogger Support Software supported telecommunications. PC300 BDR Support Software was used for programming, data retrieval, and interrogation of BDR320 by on-site laptop computer. One copy included with each BDR320 purchased.
