The (introduced starting with v12.2) use a Pro Tools Plan or Pro Tools HD Plan license.The poll message in enclosed in a frame that has the following format: where: =, i.e. Baud rate 57600 bps Data bits 8 bits Parity None Stop bit 1 Flow Control None 284 Philips 07 14023 3.2 Data frame 3.2.1 Poll sequence: frame format The poll sequence must be transmitted before sending any command, to check whether the monitor is ready to accept a command or it is busy. Function Description 1 GND Signal Ground 2 RxD Receive Data 3 TxD Transmit Data 4 NC Not Connected 5 GND Signal Ground 6 NC Not Connected 7 NC Not Connected 8 NC Not Connected 9 NC Not Connected 3.1.4 RS232 settings This section describes the parameters used during the whole communication process. The pin assignment is as following table. 3.1.3 RS232 pin assignment There is a 9-pin male connector on the set for RS232 communication. Whether it is ready or busy and other information. If the poll sequence has been sent, the acknowledgement tells the transmitter the monitor status, i.e. The hex commands for the Philips LCD screens for the Serial Xpress. Serial Xpress Protocol for interactive systems. In case of a request, the requested information is sent back and it becomes the acknowledgement by itself. After sending a command or a request in the appropriate format (see section 3.2), the master receives form the slave an acknowledgement, which tells the transmitter whether the command is not valid (or not executable, anyway) or it is accepted. The first action is always taken by the master, which can be either a built-in PC-based video controller in a MASTER monitor or any external device (acting a server) interfaced to the monitor. The protocol is specifically designed to allow data communication in half duplex multi-point environments, but it can also be used for half duplex point-to-point RS-232 communication.ģ.1.2 Communication characteristics A half duplex communication is implemented starting from the concept of a master-slave structure, where the monitor is supposed to be the slave. Serial Interface Communication Protocol 3.1 General specifications 3.1.1 Protocol definition Communication to the main monitor microprocessor is possible through the serial port, which support a communication protocol dedicated to BDS only. Oke this is the problem, i have a Philips BDL4221, i accidently locked the remote control and the onboard buttons, so i cant change the input or change anything on the tv, i tried to send some thing via 232analyzer but i have no idea what to do, the tv send me 2 messages back those are CTS turned on and DSR turned on, i found this in the user manual from the tv but i dont have any idea what to do with this: 3.
