8.0 Optional and Advanced Features
8.1 Expanded Serial Communications
The UMC600 has two serial ports. Both serial ports 1 and 2 are ASCII-compatible, RS-232, or 20 mA current loop
outputs. The serial format is compatible with most printers, scoreboards, and other remote devices. Each output can
be disabled, set for “print on demand” mode, or set to output data continuously.
8.1.1 Demand Output Serial Data Format
You can use the port or key pad to fully customize the output to work with a wide variety of printers, scoreboard
displays, and other remote equipment. To comply with legal-for-trade regulations, demand output data is inhibited
during the following conditions:
• Scale in motion
• Negative gross weight displayed
• Positive overload
• Negative overload
• Unit in “display check” mode
• Other “non normal” display mode
In demand mode, selection can be made to print gross/tare/net when in net. If either port is set to print on demand
mode, use the following format.
