PI-1604A & PI-1608A
Parallel Interfaces
The Quartz Parallel Interface is used to provide interfaces between Quartz routers and equipment requiring parallel rather than serial control e.g. Edit Controllers and custom control panels. The interface is a compact 1RU high 19" rack-mountable unit.
There are two models available supporting four or eight panel ports. The PI-1604A supports four ports and the PI-1608A eight. These units include a serial port as standard and optionally, on the PI-1608A, a second Q-Link and a second serial port.
A typical application of the Parallel Interface is to connect to custom control panels. All Quartz systems use serial communications between the matrix frames and the control panels via a single standard video coaxial cable, called the Q-Link. However, there are times when the standard panels will not fit into a desk or the buttons must be integrated into a common panel with the controls of third party equipment. The Quartz Parallel Interface is designed to meet this requirement.
The other main application offers a low cost solution where several panels are needed in the same area. Here, variants of the front panels of standard panels CP-1601A and CP-1604 are used without their normal cases. They are connected to the Parallel Interface by multi-core or ribbon cable. This is especially useful in situations where space behind the panel mounting surface is strictly limited, for instance in horizontal desks where a standard panel limits knee room.
Each port has 16 lines with read/write capability. Each line can read a button push and/or drive a lamp or LED wired to the button in the traditional button-per-source fashion. Each port also carries power for illumination. Alternatively an external source of power may be used.
Features
- Supports custom button-per-source panels

- Supports buttons with LED or 24V bulb status illumination
- Reads GPI signals
- Interfaces to VTR edit controllers with BCD or binary data format
|
- Joystick override function is supported
- Drives external relays
- Optional second Q-Link port on PI-1608A
- Serial port as standard, plus an optional second port on PI-1608A
- An optional local panel fits to the front of the PI-1604A
- Power supply provides 24V power for lamps or LEDS
- External Power Supply may be used to drive lamps, LEDs or relays
