RS-232 Protocol
This document describes the hardware interface spec and software protocols of RS-232 interface communication between ViewSonic LFD and PC or other control units with RS-232 protocol.
The protocol contains three command sections:
- Set-Function
- Get-Function
- Remote control pass-through mode
- NOTE: Below, “PC” represents all the control units that can send or receive the RS-232 protocol command.
Description
RS-232 Hardware Specification
ViewSonic LFD communication port on the rear side:
- Connector type: DSUB 9-Pin Male (or 3.5 mm barrel connector)
- Use of crossover (null modem) cable for connection
- Pin Assignment:
