7.15 RD490 UNIVERSAL PERIPHERAL INTERFACE
7.15.1
General
The RD490 Module is compatible with a broad range of VCRs, Quads, Monitors, Frame
Stores and Video Printers. The Module has the capability to support 1 peripheral device
by means of its RS-232 port, or up to 8 peripheral devices simultaneously via the 8 PPM
IR drive ports.
The module also features 8 level sensing alarm inputs, the input threshold being Dip
Switch selectable. An I.R. sensor is provided to enable the module to "learn" user
defined I.R. functions.
7.15.2
Operation
The RD490 Module can be installed in any I/O Subrack location. Connection to the
RD490 is via the 25 pin D connector associated with the subrack slot. Full D connector
pin-out defaults are as per Table 1.
In the RS-232 mode of operation, connection to peripheral equipment is achieved by
connection to the RS-232 port on the 25 pin D connector to the peripheral device (non
standard RS-232 pin outs). When interfacing via the IR PPM mode the module is
capable of driving IR LED's directly. This enables an IR LED to be located in close
proximity to the receiver on the peripheral device, control over the peripheral device is
thus achieved without physical connection.
The alarm inputs are configurable as level sensing inputs, the input threshold voltage is
adjustable to 3, 6, 9 or 12V by means of dip switches (refer to table 2). The detection
logic may also be inverted, and a self-biasing option is also available. The options allow
for virtually any peripheral device to be interfaced with ease.
The RD490 module is pre-programmed with IR data for a range of standard VCR types.
Should a function or sequence be required which is not available in the standard
selections then the "learn" mode can be utilized to user define the functions. RS-232
control sequences are also readily programmed into the module.
The RD490 module features a comprehensive test mode and error display function to
enable users to rapidly identify and resolve any difficulties that may arise.
