California Prop 65 Warning
For CA Residents Only.
California Proposition 65 Warning
Proposition 65, officially the Safe Drinking Water and Toxic Enforcement Act of 1986, is a law that requires warnings be provided to California consumers when they might be exposed to chemicals identified by California as causing cancer or reproductive toxicity. The warnings are intended to help California consumers make informed decisions about their exposures to these chemicals from the products they use. The California Office of Environmental Health Hazard Assessment (OEHHA) administers the Proposition 65 program and publishes the listed chemicals, which includes more that 850 chemicals. In August 2016, OEHHA adopted new regulations, effective on August 30, 2018, which change the information required in Proposition 65 warnings.
• WARNING: Some cable, plastic, and metal products may contain chemicals known to the state of CA to cause cancer, birth defects, or other reproductive harm.

Serial communication has been used by computers for many years though it is not as widely used in today’s market. When most people refer to serial, they think of the DB9 cable.
It is referred to as DB9 because it carries 9 pins within it. There is also DB25 in the serial family too, which obviously carries 25 pins. DB9 was typically used for devices such as gamepads, mice, keyboards, or other such interface devices.
The StarTech NM9FF null modem adapter features two DB9 serial female connectors on either end to allow you to connect two male serial cables together. This is a great cost-saving way to convert a straight through cable into a null modem cable.
Null modems are usually used to connect DTE (data terminal equipment) like terminals or printers together using an RS-232 cable. Originally, the RS-232 standard was developed and used for teleprinter machines which could communicate with each other over phone lines. This was so that you wouldn’t have to use an actual modem for transferring of information between the two devices.
