Installation and Wiring

The scale's back panel comes equipped with
a female DSUB-9 connector for the RS-232
serial port, a jack for DC power input, a cali-
bration switch, a remote display connector
(SB-30 & SB-70 only) and an ON/OFF rocker
switch. To install the scale, simply plug the
enclosed AC Wall Adapter into the scale's DC
power jack first, then into an AC outlet (115
VAC only). For SB-30 and SB-70 scales, plug
in the remote display/keyboard unit. Finally,
turn the rocker switch to the ON ("1") position.
The scale is now ready for use.
