Page 4: About This Manual
920i Introduction The BCD interface is used with 520 digital weight indicators to send weight and status information to remote displays, printers and other peripheral devices. The data is updated after each display update and continuously available for use. -
Page 5: Installation
Installation Figure 2-1 shows the BCD option card as installed in the 520 indicator. The indicator enclosure must be open to install the BCD card. The 520 has no on/off switch. Before opening the unit, ensure the power cord is disconnected from the power outlet. - Page 6 7. Plug serial cable to J3 on BCD card. Plug other end of serial cable to J8 on 520 CPU board. Use the nylon tie in the parts kit to secure the serial cable to the mounting pem (see Figure 2-2 below).

Page 9: Data Information
Figure 3-1. BCD External Connection NOTE: The 520 parallel BCD option does not have a floating ground. For proper operation, it is necessary to connect Logic Common of the BCD peripheral device to Logic Common pins 1 and 2 of the BCD option. - Page 10 MSD 2 Data Valid Bit. Informs the external device that the BCD output registers have been updated and the data is “true.” Data is not valid if the display shows other than numeric data, if the display is held (in regulatory modes), or if data integrity has been lost.

Page 14: Floating Decimal Point
Floating Decimal Point A BCD receiving device must assume the decimal point in a single location for either units (no decimal point is actually sent on the BCD lines). The BCD offers several configurations for aligning the decimal point. Refer to Table 2-5 on page 5 for dip switch settings. -
