I-O Port (J1)
All output pins of the I-O port (J1) are open collector devices.
The I-O port pins are referenced to the pin 4 ground level.
The receptacle used is an AMP 206705-1 with 66103-4 male pins. The mate would be AMP
206708-1 plug, with 66105-4 socket pins.
When the OEM TM-50 is placed in the RUN mode at
the beginning of a job, the control pins will be in the
following states:
Pin 5 - End of Job - High Impedance
Pin 3 - Ready/Busy - High Impedance
Pin 2 - Fault - High Impedance
Pin 1 - Advance - Logic High 5VDC
The sequence of the handshake controls is as follows:
1. The Advance pin is pulled down to a logic low, for no less than 10 milliseconds.
2. The OEM TM-50 will set the ready/busy line low and begin the advance process. The ready/
busy line will remain low until the advance is done and the heat sealing dwell time is completed.
While the OEM TM-50 is running this process, all advance commands are ignored. Upon com-
pletion of the advance/seal sequence, the busy/ready line will return to high and the next
advance will be accepted.
3. When the preset stop value is reached, two things happen that can be used as job done indi-
cators.
• The busy/ready pin remains at a logic low.
• The job completed pin switches to a logic low.
Releasing the busy/ready and job completed signals is accomplished by pressing the ESC key,
and re-entering the RUN mode.
