Module A-174-4 generates several control voltages and a gate signal controlled by a spring-loaded X/Y cross potentiometer (so-called joy stick). The control voltages for X and Y are controlled by the X and Y position of the joystick in the usual way. The third control voltage Z is controlled by the rotation of the spring-loaded joystick knob. The gate signal is generated by a button at the center/top of the joystick knob. As an additional feature four control voltages are generated that are assigned to the quadrants of the Cartesian coordinate system. These quadrant voltages are derived from the X and Y voltages by means of a special algorithm.
For each joystick function the non-inverted signal (X, Y, Z) as well as the inverted signal (-X, -Y, -Z) is available. The generic joystick control voltages are bipolar and range from typ. -5V (lowest position) via 0V (center position) to typ. +5V (highest position). By means of the Offset controls OX, OY and OZ a variable voltage of up to 5V can be added to the generic voltages. That way it's possible that the X, Y and Z outputs become pure positive (0...+10V instead of -5V...+5V). That's necessary if e.g. VCAs have to be controlled, because VCAs require a pure positive control voltage. The offset voltages can be adjusted by means of three small potentiometers. When the control in question is fully CCW no offset is added and the "pure" control voltages X, -X, Y, -Y, Z and -Z without offset are generated. As soon as the offset control in question is moved clockwise up to +5V are added to the voltage in question. The offset voltages are also added to the inverting outputs. With max. offset the range of an inverted output becomes also pure positive (+10V...0V instead of +5V...-5V). These six voltages are output at the sockets "X+OX", "-X+OX", "Y+OY", "-Y+OY", "Z+OZ" and "-Z+OZ". Each of these outputs is equipped with a dual color LED (red/yellow) that displays the present voltage and allows to distinguish between positive (red) and negative (yellow) voltages.
On top of this the four quadrant voltages Q1, Q2, Q3 and Q4 are calculated. A quadrant voltage becomes positive when the joystick is positioned in the quadrant in question. The absolute value of the voltage depends upon the position of the joystick lever in the quadrant. By means of the Overlap control overlapping of the voltages between the quadrants is attainable. When the overlap control is fully CCW there is no overlapping, i.e. only the control voltage of the currently addressed quadrant becomes positive, all others are zero. As overlap is increased the voltages overlap more and more. E.g. both outputs Q1 and Q2 become positive in the 12 o'clock position of the lever when the overlap control is turned up. The overlapping increases with the position of the Overlap control. We will explain this behaviour by means of a drawing shortly. Each quadrant output is equipped with a single color LED that displays the present voltage. The quadrant outputs provide only positive voltages in the range 0...+10V.
Notes:
Because of the construction height of the joystick (about 7 cm) the module cannot be installed into the cases A-100P6, A-100P9, A-100PMS6, A-100PMS9 and A-100PMS12 during transportation as the depth of the case cover is not sufficient. Into the base cases A-100PB and A-100PMB as well as in all other cases without cover the module can be installed without problems. We are about to find a solution for this problem (maybe deeper covers, but this requires also the modification of the cartons).
Because of the outreach of the lever in the extreme positions (fully left, right or down) it may be necessaey to arrange the adjoining modules in a different way or to install blind panels instead of modules. It depends upon the controls and sockets of the adjoining modules if that's necessary.
In theory it's possible to remove the return springs for the X and Y potentiometers. For this the joystick case has to be opened and the return springs removed by means of suitable tools. But because of the small friction it cannot be guaranteed that the lever will remain in the last position when it is released. That's why we do not recommend this modification. Even the warranty is void if such a modification is carried out by the customer.
The joystick is a wear and tear part and is excluded from the warranty !
For this module the bus connection is located at the top because of the position of the joystick at the bottom (in contrast to most other A-100 modules with the bus connection at the bottom)!
How much is my shipping?
Shipping is automatically calculated before you submit your payment information. Simply add items to your cart and proceed to the checkout page, where you'll be offered shipping options and their prices. In the UK it's normally around £4 for order values under £150, and free above that. Shipping to mainland EU is typically between £7 and £20, depending on the shipping method and the size and weight of the order.
Do you ship to my country?
Almost certainly - the site will give you an estimate of shipping costs if you add an item to the cart and then enter your country and postcode. If you have specific requirements (such as if you prefer UPS over FedEx, for example) then let us know in advance and we'll try to work something out for you.
Shipping methods
We use a combination of Parcelforce, DPD, Royal Mail and UPS for the UK, and for international orders it's either Royal Mail, UPS, DHL or FedEx depending on where you are in the world. If you have a particular preference then try to let us know BEFORE you order so we can look into it for you. Please note that there may occasionally be additional shipping charges if you live in a remote area, depending on what surcharges are applied by the shipper. We'll get in touch to discuss this with you in such cases.
Dispatch times
For UK orders, we normally dispatch the same working day if we get the order before 15:00. If you have a really urgent situation then of course drop us an email before ordering and we'll always do our absolute best to accommodate you.
For international orders, we normally dispatch the same day if we get the order before 13:00 but again, occasionally it might be the next day before we can send it out, and sometimes FedEx or UPS may come a little earlier than scheduled which would also push an order into the next day.
Shipping times
Since April 2020 the couriers we use have suspended guarantees for shipping times, so even though we're paying them for priority services - 24-48 hours for most of the world - in practice it's often an extra day on top and sometimes it can be longer.
There is absolutely nothing we can do about this unfortunately. If you are outside the UK and it's a life-or-death situation where you absolutely MUST have that passive mult for the next day then... it may be better to find a local supplier.
Saturday shipping
If you're in the UK and you order before 15:30 on a Friday then we can send something for a Saturday delivery (NB: this applies to UK mainland addresses only). The success rate with DPD is about 95% so it's worth a punt most of the time. Please note that if you select Saturday shipping on an order placed earlier in the week, we'll wait until Friday to ship it.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch if you have questions.
