EPP and ECP offers several enhanced features, that PC software can make use of, but the control lines are not bidirectional anymore in these modes. Here's a compatibility chart between cables and parallel ports of different modes. If you are interested in the electronical details of PC parallel ports and the X1541-series cables, please, read the Technical background information section in The Star Commander documentation. However, on most Pentium and above motherboards, setting the parallel port to SPP mode won't give you a true SPP port because of the slight changes in the electronical layout of the parallel port. Rather check the real mode of your parallel port with LPTDetect or The Star Commander. Continuity check the ribbon cable. You can check if your parallel port is compatible with the X1541 cable with X1541Test. Now you can take a 220 Ohm resistor and insert it into one set of pads of R40-R55 and see how bright the LEDs are. You should have already tested the base PCB before now, so after inserting the master PIC and the 74HC595 and 74HC165 and connecting the LCD, you can turn it on and see if the switches and rotary encoders work.

If the rotary encoders work, you can now solder their tabs now. Do proper solder joints of all the pads. For each cable, insert it from the top into the pads on both sides, checking it is perpendicular to both PCBs and maintaining both PCBs are parallel. Then use the holes of the PCB to bend the ends of the wire - insert cable so 2mm of wire (about the thickness of the PCB) is visible between the top of the PCB and the start of the insulation, then bend 90 degrees. What you do not want to do is cut, scratch, dent, damage the wire in any way, because if you do, the wire will break when bending. If you are using some ultrabright or superbright LEDs, blue or white LEDs, etc. you may want to try 2K, what is control cable 3K or higher resistors. Let's say both drives are hard-wired to be drive B. Now we don't have to setup them, but they both listened to the select B signal, while the motherboard would still want to send a signal to select A to select drive A. Here comes the twist! This suggests that while the drives and controllers should support plugging either cable in any order, when they have control over how cables are connected they prefer power before data.

February 10, 2002 -You will all note that the Discussion Forums have been down for a while now. Added a note on flashing the Professional radios with a RIB-less cable. Make sure you do not put cable in the extra "GND" pads Put all eight 8-wire cables in, plus the single 2-wire cable. I realised when I first tried to put the two shells together that it wasn't possible to close the case. Make sure there are NO SHORTS between any two adjacent pins of the ribbon cable joints. There are two other situations here which don't apply to this question. All the following situations shall not damage the device or host, and both the device and host shall resume normal TX/RX communication after any of the following events. The purpose of this section is to provide the minimum set of normative requirements necessary for a Serial ATA Host or Device to be declared as "Hot-Plug Capable". Unpowered OS-Aware Hot Plug / Removal: This is defined as the insertion / removal of a Device into / from a backplane connector (combined signal and power) that has power shutdown.

For all I know, I may have wired the pad up correctly after all and it was my inability to properly install the driver that was the problem (I'm no Linux power user. They are not hosted locally, and we do not have control over the servers they reside on. Make sure GND and 5V are not connected (the single 2-wire cable). The assembly is held together by a 5mm OD plastic housing to make a relatively stiff cable housing. Make a very small solder joint on the first and last wire of each cable. I worked in theater (at a university conference center) only briefly but the fact that it was a very small operation gave me a great deal of exposure to the cutting edge of theatrical control last time a major capital expenditure had been authorized, in the '90s. So if you wanted to be pedantic and prefer one order above the other, your best bet is to follow what they do and connect the data cable last. Rather than risk breaking something or proceeding with the ordeal of prying the hinges out of place, I drilled a hole through the plastic to reveal that last remaining screw in the layer beneath; this area being out of sight at the rear of the player and beneath the lid when closed.
