(708) 679-0900 Version 6.0 Sofhrvare Changes Laser-Disk Commands The latest version of the modules EPROM software remaps the keypad com
2、mands for the video players. The illustration on the next page shows the new layouts; you can effect them by closing switches 1, 2, and 4 on the modules DIP switch, the standard setting. To continue using the older layouts, close switches 1, 3, and 4 (i.e., close 3 instead of 2). VCR Commands The ke
3、ypad layout for the laser-disk play mode was remapped to parallel the VCR layout. For example, “2” now means “Play” for both types of players. The new layout includes three additional commands, which select the audio output from the laser player: “Channel 1” (7), Channel 2” (*), and “Stereo or Com-
4、bined Channels” (# in the Numeric Mode). These com- mands are explained in detail in the TC4411 “CPU3” manual, KI-1655A. The new VCR layout has eliminated the “Power” (6), VCR/TV” (7), and “Keep” (#) commands. In addition, it has moved the “Release” command from the asterisk key to the zero key (to
5、make the release process the same as for laser-disk players), and has added one new command: “Frame Advance” (6). EPROM Location The U7 EPROM is in the middle of the MRlOO printed circuit board, between the largest chip and the DIP switch. Its software version number is printed on its label. RAULAND

(708) 679-9900 General Information Description The MRlOO module is an
7、interface that enables a user to operate a video cassette recorder or a Pioneer LD- V2200 Laser Disk video player via a Telecenter IV push- 4 button telephone. With this system, all an institutions video players can be kept in one secure location. An authorized user “calls” the player with the desir
8、ed pro- gram, tunes the rooms television monitor to the appro- priate channel, and then uses the phones dial pad to control the player. d The MR200 is a rack-mounting chassis that holds up to six MRlOO modules. Equipment Requirements supplied Parts Qty. Description 1 6 5 5 MR100 Modules Supplied Par

For power, use either Rauland 12-VDC, 300-mA regulated supply: theVP0145 or the VPO057. Either supply will accommodate up to four MRlO
10、O mod- ules. Each supply requires a proximate AC outlet; keep in mind that these supplies will impinge upon adjacent sockets. For all the connections to the MRlOO module, use #22-gauge twistedpairs. To mate with the supplied connector, the pairs should be ma each socket is directly behind the rest o
11、f the circuitry for its line; the numbering appears along the front section of the LLM Board.) Step 2. Orient the MRlOO module with the compo- nent side of the PC board on top and the header pointing at you. Locate DIP switch “SW 1” (on the middle left side) and remove the protective tape from it. S
12、tep 3. Make sure that all four switches are set to the appropriate position: SW1 Dip-Switch Setting Desired output SW.1 SW. 2 SW.3 SW. 4 VCR 1 1 1 1 Laser disk 1 1 0 1 ASCII(for 1 1 1 0 diagnostics) I IIII 1 1= Closed O=open Notes: (1) Both the “Open” position and the individ- ual switch numbers are
13、 printed on the DIP switch. (2) For diagnostic purposes, unplug the universal re- mote control and set Switch 3 to its closed (“1”) position and Switch 4 to its open (“0”) position. This will change the control instructions to ASCII characters. A computer con- nected to the port can then provide a r
14、eadout of the digits dialed Gom a remote station. Laser Player Installation Steps 7G9L here are for installlng a Pioneer Laser-Disk Video Player; for installing a video tape player, follow Steps 7V-9V under VCR Installation,” above. Step 7L. To prepare the MRlOO for a laser-disk player, unplug Conne
15、ctor J2 to disconnect the universal VCR remote control from the MRlOO. Step 8L. Obtain or fabricate a serial control cable (see KM1005). Plug its “D” connector into the rear of the laser-disk player, and wire the other end to Pins 9 (“send”) and 10 (ground) on the MRlOO. Set the players rear-panel D
16、IP switch to “0-0” (“OF-see KM1005). Step 9L. Insert the module into its intended slot in the MR200 chassis. Continue witb the Step 10 of “Final Installation. Final Installation The units serial port comprises the last four pins on the header. Pins 9 (“send”) and 10 (ground) output the same data as
17、are sent to the remote control. Pins 11 (ground) and 12 (PC input) can be used to send signals from a computer directly to the remote control (factory use only). These concluding steps are for both tape and laser video players. Step 4. If the racks holes are not tapped, clip the four supplied Tinner
18、man nuts, flat sides to the front, over the appropriate holes. Step 10. Complete the wiring in accordance with the appropriate attached wiring diagram (for a VCR, KM 1009; for a laser-disk player, KM1005). Note that the supplied connector will fit either way on the rear termi- nals; to avoid confusi
19、on, both now and for future servic- ing, use Socket 1 on the connector for “LR,” the top pin of the modules header. Step 5. Install the MR200 chassis in the rack with the Important: On the earlier (“0”) versions of the PC supplied mounting hardware; the fiber washers go be- board, the LR and LT term
20、inals are reversed. Starting tween the flat washers and the front of the chassis, to protect the latters finish. Step 6. Remove the “U” shaped locking bar and its two thread-forming screws from the rear of the chassis and set them aside. VCR Installation Steps 7V-9V here are for the installation of
21、a video tape recorder; to install a laser video player, follow Steps 7L-9L under “Laser Player Installation,” below. Step 7V. Loosely install the #l0 hex thread-forming screw and the cable clamp on the modules mounting bracket for the remote control. Push one end of the optic cable through the groov
22、e in the cable clamp, work- ing from the rear (connector-side) of the module. Thread the cable through the hole in the plastic guide; feed the cable through until it touches the remote con- trol. Tighten the clamp. Temporarily insert the module into its intended slot in the MR200 chassis. Step 8V. C
23、ut each MRlOO modules optic cable so that it has reasonable, but not excessive, slack between the modules mounting position and the infrared receptor of the associated VCR. You can use a sharp knife or blade cutter. Step 9V. Insert the other end of the optic cable into the optic disk: insert it far
24、enough so that it will remain firmly attached, but do not insert more it than one-quar- ter inch. Do not attach the disk to the VCR at this time. Skip to Step 10 under “Final Installation,” below.

Connect the power and TC IV lines, including a gro
28、und wire from each MR1OOs common to an MI0 “Z” terminal, as shown. 6. Install one end of the optic cable through the clamp terminal and against the remote control. The cable should reach the corresponding VCR without coiling or making a sharp bend; if necessary, shorten it with a sharp wire cutters.
29、 7. Insert the optic cable into the optic disk, then center the disk over the VCRs infrared receiver chip (which may be off-center in the infrared window). 8. List each MR1OOs Telecenterdialing and TV-channel num- bers on a supplied label and attach it to the MR200 chassis. 9. Program the CPU3 (TC4411) as required by the Telecenter IV Plus manual (KI-1655). MRlOO MEDIA RETRIEVAL MODULE: VCR INSTALLATION AND WIRING Irirrnno%l
