RTSI Connector
The Real-Time System Integration (RTSI) connector allows connection to one or more NI DAQ devices. This allows I/O and trigger expansion beyond that normally available to the NI PCIe-1437. The RTSI bus should only be used with NI devices compatible with the RTSI bus.
Notice The RTSI connector is designed to work only with the NI products that have a RTSI connector. Each RTSI I/O is a bidirectional pin that is compatible with both 3.3 V (LVTTL/LVCMOS) and 5 V I/O (TTL/CMOS). No over-voltage protection, reverse voltage protection, or isolation is provided on this connector. Improper use of this connector will result in damage to the NI PCIe-1437. Use of a RTSI-compatible NI product is recommended.
