6、he MRR7800 Remote Receiver Module is part of the Telecenter MR and Rauland Ranger series of products. It is compatible with the Telecenter IV+, Telecenter V (V308), Telecenter System 21, and Ranger systems. Note: For systems using the MR100 media controller, use version 7.1 or later software. The MR

7、R7800 receives infrared commands from the MRH7700 Hand-Held Remote Controller or RANBARC Bar Code Reader. It then translates the commands into DTMF signals and sends them to a media device controller (such as an MR100 or RANDTMF). Revision History In addition to bearing a new format, this manual rev

8、ision includes new mounting procedures when using the product under high efficiency fluorescent lighting conditions (see Chapter 2). 1 KI-1845C MRR7800 Remote Receiver ModuleInstallation and Operation Page 5 of 13 (06/26/98) Installation Mounting Select a position on or near the television set to mo

9、unt the MRR7800. You may need to “shade” the unit from direct exposure to ambient light (depending on the room conditions). Point the module so that it will be able to receive signals from all parts of the room where the remote control is likely to be used. Attach the MRR7800 to the location by usin

10、g the supplied Velcro adhesive strip. Power Connection Supplied with the MRR7800 is a calculator-style 9 VDC power supply which plugs into an AC outlet. Plug the other end of the cable into the back of the receiver. If you are installing multiple MRR7800 units, a regulated 12 VDC “Class 2” power sup

11、ply can be used to remotely power all receivers. Each unit requires 50mA DC. Make external power supply connections to terminals 1 and 4 of the RJ11 “Line” jack located on the rear panel, noting proper polarity (refer to figure 1.) ? Important: Many telephones provide a contact closure on terminals

12、1 and 4 of the RJ11 jack when the telephone handset is taken off-hook. When using a remote 12V power source, be sure to isolate the telephone terminals from the MRR7800 terminals. Otherwise, the phone will short the power supply when it is taken off-hook. Telephone Connection The MRR7800 directly co

13、nnects to a Telecenter or Ranger system across the classroom telephone line. When connecting to a Telecenter IV or Telecenter V system, the Tip and Ring connection is not polarity sensitive. However, you must observe proper polarity when connecting to a Telecenter System 21. Otherwise, the 2 KI-1845

15、 Ring (Negative) 3 Tip (Positive) 4 External Ground DIP Switch Settings The unit has 12 DIP switches accessible from the rear panel. They are arranged in two groups of six switches: SW1 and SW2. The switch settings may be changed at any time, even while the power is on. SW1 Position 1: Unused. Posit

16、ion 2 (12 or 48 VDC Interface): Set to “On” for 12V telephone line interfaces (typical Telecenter systems), “Off” for 48V interfaces. Position 3 ( System 21): Set to “On” for Telecenter System 21, “Off” for Telecenter IV and Telecenter V. Position 4 (Auto-disconnect Time): Selects the time interval

17、that the MRR7800 stays connected to the telephone line in between receiving commands. Set to “On” for 15 minutes, “Off” for 10 seconds. Note that the connection time is restarted each time a command key on the MRH7700 is pressed. Position 5: Unused. Position 6 ( Ranger): Set to “On” for Ranger syste

KI-1845C MRR7800 Remote Receiver ModuleInstallation and Operation Page 7 of 13 (06/26/98) SW2 Position 1 and 2: Stored Access Code Length Set the switches according to the table below. If “2,” “3,” or “4” is chosen, any attempt to store a code of another length will

19、be rejected by the receiver, and the red “Error” LED will flash. If “Any” is chosen, the access code may be from one to four digits in length. Access Code LengthPosition 1Position 2 AnyOnOff 2OffOn 3OnOn 4OffOff Position 3: Call Progress Detection (CPD) This switch determines how the unit gains acce

20、ss to the media controller. Set this switch to “Off” for Ranger applications and “On” for all other (Telecenter) applications. When set to “On,” the unit monitors the line for dial tone, busy, ring- back, and reorder signals. If access to the media controller has failed, the red “Error” LED on the f

21、ront panel will flash. This might occur if there is a lack of dial tone or a media device has not been pre-assigned. With the switch in the “Off” position, the unit waits a fixed time before dialing. It attempts to gain access whether or not the system is ready. The red “Error” LED is not applicable

22、 in this mode. Position 4, 5, and 6: Single-Digit Access The DIP switch settings shown in the table below determine which DTMF tone is used by the MRR7800 to connect to the media controller. Using the MRH7700 Hand- Held Remote to select the access code will override these settings. If the stored acc

23、ess code is cleared, the unit reverts to the code setting of the SW2 switch.

24、 on, the green “Active” LED will flash a specific number of times, indicating the software version number (e.g., five flashes for Version 5). The flashing will then stop until media access is initiated by the user. Media Device Access The access mode is determined by the DIP switch setting. Refer to

25、 “DIP Switch Settings” in the “Installation” section of this manual. To access a media device, press a command key on the remote control or send a bar code command. The unit will go off-hook, dial the access digit(s), and then send the command digit(s). While the MRR7800 is connecting to the media c

26、ontroller, the green “Active” LED will flash rapidly. If connection is successful, the LED will either light steadily (10 second access mode) or flash once every two seconds (15 minute access mode). If the unit detects a problem, the red “Error” LED will flash. If this happens, make sure that the cl

27、assroom has been pre-assigned to the media device and that the media device is not busy. Initialization Tones Initialization tones are media commands that are automatically sent to the media controller by the MR100 in a Telecenter system every time “Access” is initiated. Use the asterisk (*) initial

28、ization command for laser Disc players. This ensures that the media device is in the command mode (not the numeric mode). Single-Digit Access Mode From the Media Center telephone with display, dial #24 to pre-assign the media device to the classroom. When a single-digit access code is set, the MRR78

29、00 dials the corresponding DTMF tone to gain access to the media device. Single-digit codes 3 KI-1845C MRR7800 Remote Receiver ModuleInstallation and Operation Page 9 of 13 (06/26/98) are set via DIP switches on the rear of the MRR7800. DTMF Tones 5 through 8 may be selected (refer to the table on p

30、age 10). Stored Access Mode The Stored Access Mode is an alternative to the Single-Digit Access Mode. The teacher stores the extension of the media controller using the hand-held remote control. The MRR7800 automatically dials the extension whenever a command key is pressed. Unlike the single-digit

31、mode, the classroom does not have to be pre- assigned (if the MR100 has previously been released). Before using a stored access code, you must first program the dialing sequence using the following procedure: The stored code may be reprogrammed at any time. 1. Point the remote at the receiver. 2. Pr

32、ess Store. 3. Press the access sequence. 4. Press Enter. ? The stored access code will be lost if power to the MRR7800 is interrupted. For example, to access a device at extension 706, the user would enter Store, 7, 0, 6, Enter. The stored sequence may be from 1 to 4 digits in length. The length may

33、 be fixed or variable, as controlled by the DIP switches on the rear of the unit (see the “Installation” section for details). When the length is fixed, the receiver will not accept an alternative length, and the red “Error” LED will flash. The DIP switches may be set appropriately for any length. A

34、 stored access code will override the single-digit access code setting. To restore single-digit access, press Store, and then Clear. Call Progress Detection Mode The unit has a Call Progress Detection feature which examines the call progress tones (e.g. dial tone and busy signal) to verify connectio

35、n to the media controller. If access fails, the red “Error” LED flashes. The Call Progress Detection feature should normally be left on, but it may be turned off via a DIP switch on the rear of the unit. When off, call progress tones are ignored and the connection is assumed to be good. Duration of

36、Access The MRR7800 automatically disconnects the telephone line if it does not receive a new command during the auto-disconnect time. Each time a key is pressed, the timer is restored to the full amount. If the unit times out, the media controller is KI-1845C MRR7800 Remote Receiver ModuleInstallati

37、on and Operation Page 10 of 13 (06/26/98) disconnected. However, the media device is still reserved, and the viewed program is not interrupted. The length of time before disconnect is programmable through a DIP switch for either 10 seconds or 15 minutes. While in the 10 second mode, the green “Activ

38、e” LED is steadily lit. In the 15 minute mode, the light flashes every 2 seconds. If access is set for 10 seconds, you may extend it to 15 minutes by pressing the “Keep Ctrl” key. The MRR7800 must be actively connected to the media device at the time the key is pressed (check that the green “Active” LED is steadily lit). Once extended, the timer will remain in the 15 minute mode until the connection is lost. Subsequen
