RS232/RS485/USB Device Function
A) The OHAUS Interface is preset to communicate using the following settings: 9600
baud, 8 bits, no parity, no handshake. Determine the RS232/RS485/USB Device
parameters required for the printer or computer that is to be connected. See the
computer or printer documentation if assistance is required. If the parameters do not
match, it will be necessary to change either the indicator's settings, or the computer /
printer settings.
B) Upon installation of the interface, the indicator will recognize the RS232/RS485/USB
Device Interface and add relevant items to the menu. Configure the indicator to the
