4-Bit Parallel
ECR Interface
The 6700 is capable of interfacing with an EIA
Standard RS-232, full duplex, asynchronous,
smart device, or 4-bit parallel interface for
output of weight data to an ECR device. The
6700 15 pin style is normally configured as a 4-
bit Parallel standard from the factory. The 6700
9-pin style is capable of RS-232 communication
only.
Serial commands will be responded to only
when the scale is in the ‘normal’ operating
mode and Switch 1 on the main board is in the
CLOSED position.
Baud Rates:
1200, 2400, 4800, 9600, or 19.2K
Word Length: 10 Bits
1 Start, 7 Data, 1 Parity, 1 Stop
Parity: Even, Odd, or None
The scale is DTE.
The 15 pin version of the 6700 is normally
shipped configured to function as a 4-bit
parallel interface device.
Follow these steps to configure the scale to
serial RS-232 interface operation.
1. Locate the dip shunt jumper at JMP2 on the
main PC board.
2. Place the jumper so the shorting pins are
located away from the DE-15 connector at
end of the PC board. See Figure 4 below.
