I posted a query to the net a week or so ago about connecting a Pioneer consumer model laser disk play to the RS232 port of my Amiga. Thanks to everyone who responded. I replied to you all individually but some mail bounced. As many people expressed interest and some of the posts to the net said it couldn't be done, I thought I'd let you all know how things worked out. It is indeed possible to hook up a Pionerr consumer model laser disk player to an RS232 port. In fact any Pioneer component that supports it's SR system can be controlled from the computer. Here's what I ended up with. Hardware: SIA-III Visual Database Systems 614 Bean Creek Road Scotts Valley CA 95066 (408) 438-8396 $200 The unit is a small black box with it's own power supply, it has two cables, one to connect to the RS232 port the other to the control port of the laser disk player (or any other Pioneer component with the SR system). The hook-up to the 3030 is a little weird, the control cable must be plugged into the control out jack and a small grounding cable connected to the control in port and the right analog output jack. There is a slight hum when the unit is connected. I presume the grounding cable was designed to prevent this. It didn't, in fact I am not sure what it's for as it did not seem to make a difference whether it was connected or not. I was able to run an extension cable and move the unit 25 feet from my Amiga. I made the cable with a couple of RS232 to telephone jack connectors and a telephone modular cable. All available at Radio Shack. There are versions available for the Amiga, IBM-PC and Apple Macintosh. There are also adapters to allow you to hook it up to the older Pioneer laser disk players that have the DIN-8 connector, e.g. CLD-900 and the 24 pin models, e.g. LD-V4000. Service: The guy on the phone at VDB was very helpful and answered all my questions. He said he would try to ship the day I called and it arrived the next morning via UPS. He told me to call back if I had any problems. Software: I understand that the IBM and Mac versions come with software the amiga version doesn't. (Actually the Amiga version is the IBM version without the software). Even without the software it's easy to use, just fire up your favorite terminal program and set it to 4800 baud, 8-N-1. The commands are actually hex codes which can be entered as /nn. The more common codes can be entered as a single character and will be translated by the unit, for example P is play, O is chapter input, S is search. The sequence O6S will play chapter 6. Writing ARexx EXEC's to interface with the SIA-III is a breeze. The manual includes all the codes for Pioneer components (LD, amps, tuners, VCR's, etc.). I am going to be investigating the use of Hypercard type software on the Amiga, CanDo, UltraCard etc., with the SIA-III. As long as you can write to the serial port, you shouldn't have any problems. There are some commercially available hypercard stack products available for the Mac. Hopefully someone will come up with a way to get these to the Amiga. Summary: If you are looking for a way to control any Pioneer SR components from your computer, the SIA-III does a very good job. I can sit at my computer and change tracks on my CD's, adjust the volume on my amplifier and position a laser disk at a specific frame all ready for digitizing with DigiView. The laser disk player responds instantly to the command, the second I press Q (for pause) the player pauses, there is no delay. The price is a little steep but I am having a lot of fun. I intend to develop software to control my player for use with DigiView. I am also thinking of building a database of all my CD's, my favorite cuts and playing sequence and let the computer program it. Now if I could only figure out a way to get my Amiga to pull the CD off the shelf and load the player!
