If the RS-232 interface does not function correctly, first check that the correct RS-232 cable is being
used, and that all cable connections are secure. Next, reset the baud rate of the scale to match the
external device. See Appendix II, "Setup Functions." Now, make certain the data formats are identi-
cal. See Appendix VI, "RS-232 Serial Data Communications." If data transmission or reception is still
not possible, be certain that the cable is the correct type. (When communicating with certain types of
devices, especially computers, it may be necessary to "cross" the receive and transmit lines of the
interface. That is, the receive line of the scale must connect to the transmit line of the external device.
Likewise, the transmit line of the scale must connect to the receive line of the external device. Special
cables can be purchased for this purpose from a computer dealer.) See Appendix VI for more infor-
mation.
If the problem still persists, contact your dealer or consult Appendix XI, "Limited Two-Year Scale
Warranty," for more information.
