PRS Infra Red
Interwrite™ PRS Infra-Red handsets
The infra-red system is in use in many locations today, and still readily available in original and high-speed types. The Cricket handset should be considered for new installations though – talk to us about your requirements.
January 2010 update: eInstruction no longer supply the infra-red handsets shown on this page, but they do have a low cost CPS infra-red handset for small classes. Banxia is able to supply these – contact us for more information.

Drivers
The drivers for the Infra Red receivers can be downloaded from SRSReceiverDrivers.exe.
Infra Red Transmitter
| Feature | Description | Benefit |
| Unique Transmitter ID |
Each transmitter has a unique ID that can be assigned to individual students. | Each student’s response can be tied directly to him or her. |
| Low Cost and No Recurring Fees |
Transmitters are owned by the student or purchasing institution. There are no online or registration fees assessed to activate the transmitter. |
Saves significant money over multiple semesters and for students using the transmitters in multiple classes. |
| Alpha Numeric Keypad |
Transmitters have alphanumeric values (i.e. 1A, 2B, 3C, 4D, 5E, 6F, 7G, 8H, 9I, 0J) | Teachers can ask multiple-choice questions that have up to 10 options and numeric valued questions. |
| High & Low Confidence Levels |
Two programmable keys allow students to indicate high and low confidence levels with their responses. | Teachers can not only gauge if the students’ answers are correct or incorrect, but how confident they were in answering the question. |
| Infrared Technology |
Receivers use infrared technology similar to a TV remote. The transmitters operate at a range of up to 60 feet from the receivers. |
Very reliable technology that operates on a “line of sight”, so it will not interfere with radio frequency equipment or other systems in adjacent rooms. |
| Wireless Option for Receivers |
Wireless transceivers allow the connection of the computer and one or more groups of receivers to be accomplished without cables. | In larger classrooms, wireless transceivers are useful to eliminate floor wiring. The wireless system may also be a cost savings for institutions requiring contractors to perform extensive hard-wiring configurations. |
| Compatible with Standard Computer Hardware |
Receivers are connected to the computer’s comm port (or a USB converted port). | Easy to install. |
