DATAGRAPH II SERIES VIDEOGRAPHIC RECORDER
HIGH RESOLUTION 6.1” SCREEN WITH UP TO 18 CHANNELS AND PLUG & PLAY I/O
The Datagraph II is the newest, most advanced paperless recorder available. It is ideal for monitoring, recording, and evaluating processes
in a variety of applications, including: laboratory, chemical, petrochemical, semiconductor, automotive, food & beverage, and environmental
monitoring.
The Datagraph II is the first modular paperless recorder that allows for up to 18 analog inputs or a mix of analog and digital I/O cards. Other
industry-leading features include: high-resolution color display (640 x 480 pixels), infrared detector for prolonged display life, plug & play I/O
card, shallow unit depth, and user-friendly interface. The low-voltage and bench-top kit options also make the Datagraph II ideal for portable
applications.
Multiple display formats and easy-to-access keys make monitoring and setup extremely easy. Data can be stored in flash ROM, on a
compact flash card, or on a PC via RS232/422/485 or Ethernet options. The Datagraph II meets CE approval standards.

Notes:
• The recorder is built with 6 rear slots. These slots and a com-
bination of input/output cards restrict the ordering code above.
For example, 12-channel analog input requires 4 slots tted with
3-channel analog input card, VG18-AI3, leaving 2 empty slots
for other I/O cards.
• The basic PC software Observer I is supplied free with the
recorder. There is an additional charge for the extensive PC
software, Observer II (VG18-SW2), for use with
RS-232/422/485 or Ethernet communications option.
