RS-232/422 serial line connection with an ESA video terminal
The RS-232/422 connection of the ESA terminal with the drives is made
through the MSP connector located at the bottom of the VT module. See

MSP connector of the ESA video terminal for the RS-422 connection.
The MSP serial port (Multi Serial Port) is a part of any ESA video terminal
and is used to connect it with other devices. Hence, the project is
transferred from the PC to the VT through this port.
This port is accessed from a 25-pin female SUB-D connector and may establish
communication with other devices through RS-232, RS-422, RS-
485 and C.L. (TTY-20 mA) protocols.
NOTE. Pin 16 does not contemplate communicating with any type of
load. Any disturbance going into this pin can damage the video terminal
and the process.
The pinout of the MSP connector is described in the following table:
