The VLR-100 can be factory upgraded to the VLR-100PC. The VLR-100 comes standard as a desktop unit and can be installed in a standard 19" rack using an optional rackmount ear kit, or can be attached to a wall or other piece of equipment using an optional wall mounted swivel bracket kit.

Page 7: Smpte Time Code Chapter
Depending upon the playback capabilities of the video recorder, the VLR-100 can read and decode LTC signals at speeds as slow as 1/30th times play speed up to speeds as high as 100 times play speed. - Page 8 numbers progressing from ..28, 29, 00, 01, 02, etc., drop frame time code advances from frame 29 to frame 02, skipping frame numbers 00 and 01, progressing from …28, 29, 02, 03, etc. at the start of each minute. Although drop frame time code is widely used in the broadcast industry, if real time is not an issue it is often avoided elsewhere due to the nature of it’s unconventional numbering system.

4.1 Connecting Power Included with your VLR-100 is an AC power adapter that provides a 9 volt, 500 milliamperes DC output. This adapter is equipped with a miniature phone plug with the "+" (positive) voltage output connected to the front tip of the plug. - Page 10 4.5 Connecting Serial COMM (VLR-100PC Only) The HORITA-supplied serial interface cable connects the VLR-100PC COMM connector (3.5mm phone jack) to a DB-9 male connector compatible with most PC RS-232 serial port interfaces. For a USB connection an RS-232-to-USB adapter cable can be used.

Page 11: Operating The Vlr-100 Chapter
Because it takes an entire frame time to read the LTC number, the VLR-100 updates its display value by one frame so that it is always showing the frame number it is reading. This process is known as "on-time updating" and is generally used by all of HORITA's Longitudinal Time Code Reader products to ensure the greatest accuracy. -

-30, -60, -90, or -120 seconds. If the MODE switch is held in its SET position while the VLR-100 is powered up, the automatic backtime preset selection mode is immediately entered. As long as MODE remains in the SET position, the display will sequentially change between 00:00:30:00, 00:01:00:00, 00:01:30:00, and 00:02:00:00, once per second. -

LTC generator presets to the last good time code read, but remains in its STOP mode. If the SELECT switch is in its VITC position when the MODE switch is changed to GEN LTC then the VLR-100 enters the VITC-to-LTC translation, which is described in more detail further on in this manual. -

Page 15: Display Description
Figure 5-1, VLR-100 LED Display When displaying reader time code data, the VLR-100 automatically shuts off display of the frame digits whenever the tape speed is above two times play speed. (The frames digits can be permanently blanked via the setting of an internal jumper, see Chapter 6.) Four of the discrete LEDs indicate the operating status of the VLR-100 as follows:... -

1. Check all cables for opens or shorts. 2. If using an AC power adapter different from the one supplied with the VLR-100, make sure it supplies the VLR-100 with at least 9 volts (maximum of 14 volts) when the VLR-100 is switched on. -
