TPS150 Switching and Transmission System 4 Chapter Four Serial Communications ICS100 Windows-Based Control Program Serial Commands
Serial Communications, cont’d Serial Communications The transmitter must be programmed with commands to be sent upon input selection and with projector power on/off commands before those commands are sent. The transmitter can also be configured with several serial port variables to match the controlling device and the device to be controlled. You can program and operate the transmitter either by using the ICS100 Windowsbased control program or by sending individual ASCII commands.
Establishing communications with the program The TPT150 transmitter will not operate properly unless it is connected to a powered TPR150 receiver. Start the control program and establish communications with the TPT150 as follows: 1. Click Start > Programs > Extron > ICS100. The control program window appears. The TPS150 does not respond until it has been contacted with the valid address.
Serial Communications, cont’d The transmitter’s serial port is factory-configured to 9600 baud, no parity, no flow control, half-duplex mode. If desired, the computer’s serial port settings can be changed from within the ICS100 program. 2. Click Communications > Comm Port > Comm 1 (or the correct Comm port). The Serial Port setup window appears (figure 4-3). Figure 4-3 — Serial Port setup window 3.
9. Click Inline Model > Query Hardware to configure the ICS100 program to communicate with the TPT150 and to confirm that communications have been established with the transmitter. The connected window appears (figure 4-5). Figure 4-5 — Connected window 10. Click OK. 11. Use the software to configure serial port settings, program the input and projector codes, and/or operate the transmission system. See the procedures on the following pages.
Serial Communications, cont’d Using the software to configure the serial port settings If necessary, use the ICS 100 software to change the serial port settings of either the transmitter or receiver. The transmitter’s serial port is factory-configured to 9600 baud, no parity, no flow control, half-duplex mode. If desired, serial port settings can be changed from within the ICS100 program. 1. Click Communications > Comm Port > Comm 1 (or the correct Comm port).
Using the software to program the input and projector codes Use the control program to program the transmitter’s input selection and projector power on/off buttons as follows: 1. Click Controls > Projector Codes > Input Codes. The Program Projector Codes window appears (figure 4-7). Figure 4-7 — Program Projector Codes window 2. For each input or projector code to be programmed: a.
Serial Communications, cont’d c. Enter the desired code in the code window (figure 4-9). Spaces are ok when you are entering ASCII codes. Figure 4-9 — Code entry (ASCII code) Codes that are intended to be hex codes must be in pairs (such as 03 or DE). Use a leading 0 if necessary. Letters must be uppercase. Spaces between bytes are acceptable in ASCII codes (figure 4-9), but are not allowed in hex codes (figure 4-10).
3. Repeat step 2 for each button or code to be programmed. 4. Click 5. Click Controls > Projector Codes > Projector Delay. The Program Projector Delay window appears (figure 4-13). in the upper right corner of the window to close the window.

Serial Communications, cont’d With the exception of input audio level, the controls on the control panel window operate the same as the physical front panel of the transmitter. See chapter 3, Operation. 2. If you click the Projector On or Projector Off button, the Projector Power LED on the transmitter’s front panel blinks while the delay times out. All front panel operations are disabled during the delay. The button mutes and unmutes the audio output.
Serial Commands Communication protocols The transmitter’s and receiver’s serial ports (figure 4-16) are factory-configured to 9600 baud, no parity, no flow control, half-duplex mode. If you change the transmitter’s serial protocols, communications between the computer and the transmitter are lost until the computer is updated to match the new transmitter settings.
Serial Communications, cont’d When the system is in Pass-Through mode [CC98], commands and responses are sent between the transmitter and receiver. If the system is not in Pass-Through mode, all of the receiver responses to the transmitter’s button commands are buffered until you return the system to mode, at which time the buffered responses are sent back to the controlling device. In this way, the controller can track the activity that has occurred.
