AEC-BOX-30/30G/31/32 Literature AEC-BOX-30/30G/31/32 SERIAL TIME The AEC-BOX-30/30G/31/32 products were designed to effectively add time code capabilities to serially controlled "Sony protocol" VTRs. This serial protocol is used by many high quality VTRs, including the Sony U-matic, Betacam, 1-inch, digital video, and Panasonic MII machines. The LTC and/or VITC data is read and inserted into the serial data stream by the AEC-BOX-30/30G/31/32 as needed. The AEC-BOX- 30G can also generate analog LTC. In addition, all models properly control the VTR during prerolls, searches, auto-edits, etc., without any intervention required from the controller. Each AEC-BOX-30/30G/31/32 is small (modem sized), rugged (all metal), and attractive. For both reliability and convenience, an internal power supply is used, for which 115VAC/230VAC is required, and which is Hi-Pot tested for your (and our) safety. Installation is very easy. Standard 9-pin RS422 cables are used from the AEC-BOX-30/30G/31/32 to both the controller and to the VTR. Also, the LTC/VITC outputs of the VTR are connected to the appropriate inputs on the AEC-BOX-30/30G/31/32 (VITC inputs are Hi-Z looping). Other than that, no setup work is required. ALL documented (and many undocumented) "Sony protocol" serial commands are supported. We believe that the AEC-BOX-30/30G/31/32 will work with any controller which is designed to control such VTRs. Our 15 day money back guarantee on this product, if you are not fully satisfied, supports this claim. Please call us at 1-800-782-2321, or at the number above, if you have any questions. We look forward to hearing from you. Sincerely, Tracey Ruesch, President P.S. If your application requires something a little different from what you see here, please give us a call. These boxes (and their software) have been designed with customization in mind. Since we are a small company, we can (usually) respond quickly to your particular needs, and at a reasonable price.

LTC READER NOTES The LTC reader uses a proprietary integrated circuit to read even poor quality LTC signals from (theoretically) 1/30x to 50x play speed, in both the forward and reverse tape directions. In cases where the LTC signal is unreadable, such as below 1/10x with many VTRs, the VTR's control track pulses are used to automatically adjust the LTC data as needed. VITC READER NOTES The VITC reader uses a proprietary integrated circuit to read even poor quality VITC signals from at least -1x to STILL to +3x. In cases where the VITC signal is unreadable, such as at search speeds, the VTR's control track pulses are used to automatically adjust the VITC data as needed. Normally the VITC reader just reads the first two VITC lines it sees in each vertical interval. Alternatively, you may specify which two VITC lines are to be read via DIP switch programming (described in the manual). AUTO LTC/VITC READER NOTES The AEC-BOX-32 has both LTC and VITC read capabilities. In addition to the LTC and VITC reader notes above, this box automatically switches back and forth between reading LTC and VITC, depending upon which signal has the fewest read errors. LTC GENERATOR NOTES The AEC-BOX-30G includes an LTC generator with an analog LTC output, plus a Hi-Z looping video sync input to synchronize the LTC output to the desired video reference signal. The LTC output is activated by RECORD, ASSEMBLE EDIT, and INSERT EDIT (with LTC track selected) commands from the controller. The AEC-BOX-30G cannot be used as a standalone LTC generator - it only responds to serial commands from the controller. USES FOR THE AEC-BOX-30/30G/31/32 The most obvious application is to effectively add LTC and/or VITC time code reader capabilities to serially controlled VTRs which do not have internal time code readers. The AEC-BOX-30G can also generate analog LTC. The AEC-BOX-32, with its LTC/VITC reader, can also be used to add VITC read capabilities to an "LTC only" VTR. Another important use (pointed out by several of our customers) is the ability to recover (and use) tapes which have had LTC recorded onto one of the audio tracks instead of on the LTC track. VTRs with internal LTC readers are helpless in this situation. SPECIAL NOTES FOR JVC CR-600U AND JVC CR-850U VTRs The RS422 serial port on these machines is only about 2/3 "Sony protocol" compatible, which leads to big problems with many edit controllers. The AEC-BOX-30/30G/31/32 automatically sense the presence of these JVC VTRs and provide full protocol translation in addition to the box's time code capabilities. Your edit controller will then believe that it is talking to a real "Sony protocol" VTR, saving your JVC machines from obsolescence. SONY VTR EMULATOR SOFTWARE INCLUDED If no VTR is connected, the AEC-BOX-30/30G/31/32 automatically enters the "Sony VTR Emulator" mode, during which it reads LTC/VITC and emulates a "Sony protocol" VTR all by itself. This allows use of the box with tape logging software and inexpensive VHS tape machines. The AEC-BOX-30/30G/31/32 then automatically reverts to normal operations as soon as an RS422 VTR is detected, facilitating use with RS422 routing switchers and patch panels. NTSC/SMPTE AND PAL/EBU COMPATIBILITY Each AEC-BOX-30/30G/31/32 senses whether an NTSC or PAL type VTR is present, and automatically adjusts its operations as needed to handle the types of signals present. No setup work of any kind is required to switch between NTSC/SMPTE and PAL/EBU operations.
