Hypertherm Phoenix 8.0 - Manual (Page 545)

MicroEdge
538
A remote communications link can be connected to one of the two serial ports and an
external ground (PE) lug for earth grounding of the unit is also provided.
Serial Port
Please refer to the Ports Information section of the Installation Guide for additional
information on configuration of Serial ports for communication. Note: Serial ports for
the MicroEDGE are not optically isolated. Appropriate grounding or after market port
isolator or protocol converter to add optical isolation is recommended.
I/O Configuration
The cables that connect the control to the cutting machine are attached to the I/O
(Input/Output), and the DRIVE/ENCODER connectors. For the purposes of this guide
Single Ended I/O is referred to as Type “P” configuration.
The information provided here is the basic information for connection of the shape
cutting control to the cutting table. Each machine interface will vary slightly based on
the cutting table configuration and features. Additionally, I/O pinout information may
vary slightly based on the configuration of the selected I/O and their locations. Changes
to the I/O configuration may be made in the password protected I/O screen. All controls
are shipped with the default selection of Inputs and interface locations for the selected
control Interface (I/O) configuration. Installation and service should only be performed
by a qualified service technician.
I/O Connector
The I/O connector is a standard sex circular CPC connector from AMP. This connector
was specifically chosen for its rugged industrial design and its metal insulation
characteristics for EMI/RFI noise immunity.
In the single ended I/O scheme, a ground is provided on the I/O pin. The advantage to
single ended I/O is that it takes one pin for each point versus two for the double-ended
I/O scheme, thus increasing the total number of I/O points available to the user.
