Product Summary Summary

  • The 20mA sink digital I/O port consists of 12 individual TTL-compatible lines (Ch, #1...#8), each of which can be configured as: digital input bit, digital output bit, control output, clock output43 . When configured as an input, a channel can be used to sense a digital high (2.1 to 30 Volts) or digital low (-10V to .65Volts). When configured as an output, a channel can be set high (e.g. >2V) or low (e.g. <0.8V). These I/O pins are short-circuit protected against high voltages up to 32.0V and down to -16.0V.

  • The 200mA sink digital I/O port consists of 16 individual TTL-compatible lines (Ch#9...#24), each of which can be configured as: input or output bit44 . When configured as an input, a channel can be used to sense a digital high (2.1 to 30 Volts) or digital low (-10V to .65Volts).

Description 12 Bidirectional Digital I/O The 20mA sink digital I/O port consists of 12 individual TTL-compatible lines (Ch, #1...#8), each of which can be configured as: digital input bit, digital output bit, control output, clock output. When configured as an input, a channel can be used to sense a digital high (2.1 to 30 Volts) or digital low (-10V to .65Volts). When configured as an output, a channel can be set high (e.g. >2V) or low (e.g. <0.8V). These I/O pins are short-circuit protected against high voltages up to 32.0V and down to -16.0V.
Function Multiple Options Software programmed to one of: digital input bit, digital output bit, control output, clock output. Clock output options are: 24MHz, 12MHz24 , 6MHz, 1.5MHz, 1MHz, 375KHz, 100KHz, 94KHz, 23KHz, 10KHz, 5.9KHz, 1.5KHz, 1KHz, 366Hz, 100Hz, 92Hz, 23Hz, 10Hz, 5.7Hz, 1.4Hz, 1Hz, 0.358Hz, 0.0894Hz. Control output options are: pulse low when rd/wr from Dio Ch9..24 port (Cs2), pulse low when read from Dio Ch9..24 port (Cs3), pulse low when rd/wr to Uio 25..28 port, pulse low when read from Uio 25..28 port, pulse low when in software reset or power is off.
" input or output bit Each bit is independently software programmed as an input or output
Maximum Sample Rate17 166Ks/sec/aggregate Input70 digital data at a maximum sample rate of 166K sample/sec for 1 channel. More channels involve slower rates, e.g. 83Ks/sec per channel for 2 channels, 41Ks/sec/ch for 4 channels, and 20Ks/sec/ch for 8 channels. Things that decrease High Speed I/O sample rate: longer computer to instruNet cable, i330 optical-isolator. Sample rate is set accurate to 50 ppm (e.g. user specifies 20000 s/sec yet system actually digitizes at 20001 s/sec). Minimum sample rate is 0.015 samples/sec/ch.
Maximum Update Rate 41Ks/sec for 1ch Update 1 output channel at 41K sample/sec. More channels involve slower rates, e.g. 27K sample/sec per channel for 2 output channels
TTL Compatible Yes Supports 0.8V for logic 0 and 2V for logic 1, which is typical for TTL
3.3V CMOS Compatible " Supports 1.1V (3.3V*.35) for logic 0 and 2.3V (3.3V*.7) for logic 1, which is typical for digital Cmos powered by 3.3V
