YTerm Software Manual
Editor Only: If YTerm is to be used for viewing or editing programs while a
controller is not present, select Editor Only. This will allow YTerm
to operate without using a communications driver. Only the
programming window will be accessible in the Editor Only mode.
Note: If the controller is in “monitor mode”, a mode where the firmware
is not executing, YTerm will detect this and assume that a firmware
upgrade attempt has previously failed. If this is the case, YTerm will
attempt to download firmware to the controller again if requested. This
feature is only applicable if connected to an SMC–3010 or SMC4000
controller.
When establishing communications with an SMC, check all cable and power
connections. Make sure that the cable between the computer and motion
controller is plugged into the correct computer port. Verify the computer port
matches the one selected in YTerm.
Press Test (A) to try to establish communication once more and press
Continue (B) upon seeing the connection screen.
If problems persist, contact technical support.
Press Editor Only (C) to work in offline mode if there is no SMC
connected. In offline mode, only the Programming screen is available.
Press Exit (D) to exit YTerm.
Note: All SMC units are configured for 19200 baud rate by default.
