Modular I/O Emulation Unit

I/O tests on processor-based boards

This modular I/O Emulation Unit can be used in conjunction with our Manufacturing Test and Hardware Debug Solutions for processor-based boards. It allows I/O ports on the unit under test to be functionally tested, without the need to attach real devices. Test execution is accelerated with greater diagnostic resolution.

Construction details

The unit contains a backplane with universal connectors for adding up to 16 modular I/O cards, in any combination. The card shown below is a General Purpose I/O (GPIO) card, which provides 5 x 8-bit bi-directional lines.

Cards available for the modular I/O Emulation Unit:

• Keyboard / Mouse (3 ports)
• USB (4 ports)
• Serial (2 ports) & IrDA (1 port)
• Parallel (1 port)
• Ethernet LAN (1 port) / IEEE 1394 - Firewire (2 ports)
• SCSI (1 port)
• IDE (1 port)
• Video (1 port - RGB voltage level checks; V-Sync and H-Sync frequency checks)
• LCD (1 port - high speed serial line checks, inc. shorts, opens; V-Sync and H-Sync frequency checks)
• Audio (3 stereo mic outputs, driven by tone generator; 1 stereo line input; 1 stereo speaker input; 1 mono I/O)
• Modem - Line Simulator (1 port - simulates ring voltage, dial tones, line off hook, etc.)
• Battery Emulator (1 port - includes power supply and emulates a battery in various states, e.g. on charge, discharge, AC adapter plugged in/out, individual cell status, temperature, etc.)
• Switch Card (16 x MOSFET's < 1.1A @ 60VDC, 1 x DPDT Relay < 4A @ 250VAC or 30VDC)
• GPIO (1 port - 5 x 8-bit bi-directional lines)
• Analog/Digital (1 port - 8 programmable DAC output channels; 12 programmable ADC input channels with selectable voltages ranging between +/- 5V and +/- 25V; 4 programmable ADC input channels with selectable 2V, 4V ranges and active gain stage)
• Prototyping Card (PTH matrix, CPLD 64 I/O lines)

Preprogrammed Tests

A range of test programs and application notes is available for use with the I/O Emulation Unit cards.
