The Meridian Technologies Digitally Encoded 2 Unidirectional Audio Channel, a part of the SA series, can receive two 24-bit unidirectional audio channels over a single optical fiber. This series is compatible with Meridian's SpectraSmart Network Management and diagnostic PC based systems, which offer real-time identification of faults and out-of-tolerance conditions. The channels are used in intelligent transportation systems (ITS), security and surveillance, and access control.

Local indicators allow you to view the operations of each audio signal; local LED status Indicators help monitor system diagnostics and performance parameters. For single mode fibers, laser based systems are used; for highly reliable and repeated output, Surface Mount Technology (SMT) is used. FC optical connectors and hot swappable rack cards allow you to remove the card even when the system is operational. To obtain stable optical laser output over full temperature range, it has a back-biased photo detector circuitry.

The unidirectional audio channel uses internal switching power supplies and meets NEMA TS1 / TS2 & CALTRANS specifications. To provide protection from fault currents, the equipment has automatically resettable solid-state current limiters on all power lines. Wide optical dynamic range allows clear image capture even when lighting intensities vary widely across the field-of-view. It has a 3-pin screw terminal connector for convenient and easy connection of the audio channel interfaces.

accessible Greek for all
Format: Paperback
I got this book for my wife, who is a complete Greek novice. She enjoys it. And it is accessible for her. The book is divided into three sections, where each section gives an increasingly in depth summary of nt Greek. This is a great idea; if you only want to know the basics, do section 1. If you want to know a little more, perhaps do section 2 as well. Section 3 starts to get into the basics that you would hit in a first year text book. This is not a replacement for a first year textbook; this is for someone who doesn't want to commit to a first year textbook. For a extra fee, you can order helpful videos done by the author himself.

VERY GOOD FOR ITS PURPOSE, SOME RESERVATIONS
Format: Paperback
To same space, WM= William Mounce. BBG=Basic Biblical Greek Grammar. This is an expanded edition of the earlier book of the same name. One will recognize many elements of the author's BBG, but this is more of "how to use Greek for exegesis" so it doesn't have a lot of paradigms etc. WM even puts in the "professor" character from the BBG 3rd ed. He has chapters on word studies, translations, textual criticism, advice on how to use commentaries, etc. It's written at an elementary level so it's an excellent guide for someone just wanting to understand more deeply the scriptures, or to check the accuracy of translations. If one wants to go more in depth, he/she can consult the intermediate grammars like Gerald L. Stevens or Wallace (that one is really detailed!). WM divides the book into sections of increasing depth - Fundamental Greek, Church G., & Functional G. He deals with verbal aspect in several places. He says tenses do have the time element in the indicative mood, but it's second to aspect. Outside the indicative, only aspect is a factor. The 3 are UNDEFINED, CONTINUOUS, and (traditional perfect) complete w/ continuing results. Whether the traditional perf/pluperfect is THE meaning of the tense, or an aktionsart, I will leave to the reader. Sometimes these 2 tenses represent a state. The traditional perfect is there much of the time, determined by the meaning of the verb and context. One should look at how the verbs are actually used (sometimes it's really hard to tell why the perfect was used). Perhaps the old proverb applies to Greek i.e. "the only hard and fast rule, is that there are NO hard and fast rules". The book is helpful for students of the word. One can learn the plan of salvation from good translations, but knowledge of the Greek can answer questions, like the seeming contradiction between (ROM 3:23 & 1 JOHN 1:08,10) with (1 JOHN 3:06,09). Or the question of why Jesus told Thomas to touch Him, but said to Mary "touch Me not" in (JOHN 20:17). Understanding the (normally) continuous/repeated of action of the present tense can answer these questions. I believe the book has a few flaws (thus 4 stars). I think WM gets some things wrong, like when he says a commentator should never say something in the Bible is clear or obvious. One might say this about figurative language - like REVELATION, but if the Bible isn't clear about say, what one must do to go to Heaven, then what's the point? Also WM says on pg 126 (2nd "dot") a student can't "argue" with a commentator or a translator - he/she doesn't know enough Greek. One doesn't have to be a scholar to be able to see when someone is putting in his/her own theology (at least there are enough clear passages in the Bible that one shouldn't have to). The great scholar A.T. Robertson mentions this on pg 389 of his "big book" - there comes a point when grammar stops and theology takes over. Even WM says there're commentaries he doesn't recommend. I recommend the book. As to the few problems, always remember what Douglas K. Stuart said in his book on commentaries "just because one is a PHD, doesn't NECESSARLY mean that he/she is right and you're wrong". Always let the Bible speak for itself.

Greek for the Rest of Us
Format: Paperback
I wish I had had this book when I first started New Testament Greek back many years ago. (I'm sure my grades would have been better, and my understanding much better.) I got this book to brush up on my Greek and it has helped a great deal.
