20-7 Data Communications Precautions
Note the following precautions whenever you perform data communications.
• A TRANSMIT 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.
• A RECEIVE ERROR occurs whenever the receiving unit does not receive any
data approximately six minutes after it is set up to receive data. When this hap-
pens, press A to clear the error.
• A TRANSMIT ERROR or RECEIVE 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.
• A MEMORY FULL occurs if the receiving unit memory becomes full during data
communications. 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.
