TOUCH SCREEN (optional) & SCOM / BIT Interface:
The connector provides dual functionality for Touch Screen and SCOM/BIT interface. The relevant touch screen pins
are unconnected for non-touch screen models. There are different approaches to utilize this connector. They are:
1: For TOUCH SCREEN & SCOM usage simultanously, the provided VSD100641-1 cable designed for HM 20T07 models must
be used. A commercial standard RS232 cable will not work!
2: For SCOM usage ONLY, the VSD100641-1 cable designed for HM 20T07 models must be used.
3: For TOUCH SCREEN usage ONLY, a commercial standard RS232 cable will work (no need to use the VSD100641-1 cable)
TOUCH SCREEN:
Connect your cable to the D-SUB 9P Connector (female) on the rear side of the unit. Connect the other end to your
COM port of your computer. Install the nesscessary software needed to operate it. Fasten it using the regular
mounting screws on the cable itself and make sure you don’t bend any of the pins inside the connector when
connecting.
SCOM/BIT Interface:
The serial remote control connector (RS232) for controlling backlight and display parameters.
Connect the combined serial/touch cable (VSD100641-1) to the D-SUB 9P Connector (female) on the rear side of the
unit. Connect a standard serial cable to the SCOM/BIT connector on the combined serial/touch cable and connect the
other end to the COM port of your computer. For simultaneous use of SCOM/BIT and Touchscreen interfaces use the
other connector on the combined serial/touch cable. For extended documentation on usage, refer to the appendix in
this manual.
