21-7 Data Communications Precautions
Note the following precautions whenever you perform data communications.
•An error occurs whenever you try to send data to a receiving unit that is not yet
standing by to receive data. When this happens, press A to clear the error and
try again, after setting up the receiving unit to receive data.
•An error occurs whenever the receiving unit does not receive any data approxi-
mately six minutes after it is set up to receive data. When this happens, press A
to clear the error.
•An error occurs during data communications if the cable becomes disconnected,
if the parameters of the two units do not match, or if any other communications
problem occurs. When this happens, press A to clear the error and correct the
problem before trying data communications again. If data communications are
interrupted by A key operation or an error, any data successfully received up
the interruption will be in the memory of the receiving unit.
•An error occurs if the receiving unit memory becomes full during data communi-
cations. When this happens, press A to clear the error and delete unneeded
data from the receiving unit to make room for the new data, and then try again.
•To send picture (graph) memory data, the receiving unit need 1-kbytes of memory
for use as a work area in addition to the data being received.
