NOTE 1 - All rear panel connectors are accompanied by wire harnesses with MTA connectors installed. The purchaser must solder the harnesses to the connectors unless he selects the 'ASSEMBLE CABLES Option below.
NOTE 2 - We offer two power supplies for the DRO-550. One is supplies 9vdc @ 1.0 amps, which is sufficient for the DRO-550 with 3, 1.5vdc "Chinese" scales. If you are using more than 3 scales, using RS-232, powering an external tachometer or using 5vdc scales we recommend choosing our 12vdc @ 2.0 amp model.
NOTE 3 - DELETED
NOTE 4 - Depending upon the scale types used, you may have need of Mini-DIN, DB-9, Mini-USB (iGaging) or another type of scale connector for your kit. In the options below, you may select the number of Mini-DIN, Mini-USB and/or DB-9 openings (up to 5 total) you want for your case. We will match your internal scale cables to the type/combination of openings you request. If you want a different configuration, please include it in the notes area provided during checkout. If you require a connector other than MiniDIN. Mini-USB and/or DB-9, you may request ZERO scale connector openings be milled into your case. We will then provide MTA connectors with 6" pigtails attached. You may then connect these to the connector or your choice. PLEASE NOTE THAT Mini-USB CONNECTORS ARE EXTRA COST. SEE OPTIONS BELOW. IF YOU SELECT Mini-USB SCALE OPENINGS WITHOUT SELECTING Mini-USB INTERNAL CABLES, YOUR KIT WILL BE SHIPPED WITH MTA CONNECTORS WITH PIGTAILS FOR YOUR INTERNAL SCALE CABLES.
NOTE 5 - Optional RS-232 Internal Cable includes additional 3 pin MTA-100 connector for board.
NOTE 6 - The ShumaTech BOM calls for 2 MTA-100 2 pin connectors mounted on the board. The 2nd connector is a 5vdc output. We do not include it in the standard kit and recommend that it not be installed unless needed. Mistakenly connecting the power supply to this connector could, and most likely would, damage the DRO-550 board. If you need this 2nd 2 pin MTA-100 connector, just mention it in the notes section of your order (at check out time) and we will include it at no charge.
REMEMBER - THE TOTAL NUMBER OF SCALE OPENINGS MUST NOT EXCEED 5.
