Printer Installation (J1 RS-232)
A Liquid Controls meter system with a LCR 600 typically includes an Epson slip printer or roll printer. The installation is the same for either printer.
An LCR 600 is typically shipped with a black-sheathed data cable prewired to terminals J1 and J3 on the LCR 600 CPU board.
See instructions in Routing Data and Power Cables for routing the data cable from the back of the truck to the cab.
