Logical Systems Frequently Asked Questions

1.
Q. Is there a minimum adapter order price or quantity?
A. No, there are no minimums.
2.
Q. Does Logical Systems have adapter distributors in the U.S.?
A. Digikey is our only authorized U.S. distributor however some programmer, emulator and adapter manufacturers package our adapters along with their products.
3.
Q. Are a printed catalog and pricelist available?
A. There is no current printed catalog. We have decided to concentrate our resources on an extensive and completely informative web site. Our next catalog will be in the form of a line-card. There is a pricelist in .pdf format here. Clicking on a part number on this web site will get you a window that includes the price, photo, and datasheet link for that item.
4.
Q. Are replacement test sockets available and can I just purchase test sockets?
A. Yes, virtually all of our adapters have replaceable sockets and we keep a small supply in stock. See your adapter data sheet for the socket part numbers and type them into our search box at the top of any page.
We can order non-stock sockets for you but we are not an authorized or stocking distributor of sockets. See resources/links for suggested sources.
5.
Q. Are adapters returnable?
A. Yes. Please call or email to discuss the problem and obtain an RMA# before returning any items.
6.
Q. Does the U.S. list price apply to adapters purchased from overseas distributors.
A. No, our distributors may set their own pricing.
7.
Q. Does Logical Systems sell eprom programmers or emulators?
A. No, we have no plans to sell programmers or emulators. See resources/links for suggested sources.
8.
Q. Will PLCC adapters accept LCC packaged devices? 
A. Yes, but you will need to order the lidded socket and ask us to include a "shim" for a proper fit.
9.
Q. What are the differences between auto-eject and lidded sockets?
A. This is mostly a matter of personal preference. Auto-eject sockets are convenient and less expensive but the pins may become damaged by improper device insertion. A vacuum pen should be used to insert and remove devices from the sockets. In a pinch a piece of tape on a pencil eraser makes a workable insertion and removal device. Lidded sockets are more durable and less likely to be damaged by fingertips but they are also larger and we do not recommend them for gang programmers.
10. Q. Are adapters RoHS compliant?
Some of our adapters are available RoHS compliant upon request.
