User Manual . All lines are fully 16 bit latched for both inputs and outputs. A special mode of operation is included connecting the 2 handshaking signals to allow maximum transfer rates. 5532DMA can access 2 external PC DMA lines to allow essentially simultaneous operation for data in and data out of the host computer in 16 bit output format. Maximum transfer rate under DMA operation in an XT system is 200,000 bytes per second.
Actual rates are a direct function of the speed of the computer used.
All lines are configured with pull-up resistors to allow direct connection to dry contacts. The 5532TTL is also compatible with LabVIEW , Test Point , LabTech Notebook , and LabTech Control . How To Order 5532TTL 32 Channels of TTL Level Inputs, Operates Under Program Control and Program Interrupt Control, Includes User Manual. 32 Channels of TTL Level Inputs, Operates Under Program Control and Program Interrupt Control.
