232LB9R - 9-PIN RS-232 line booster
by Advantech/ B+B Smartworx

The 232LB9R is a 9-pin RS-232 repeater that re-transmits all 8 signals and carries the ground line through. Many CE computers, laptops, and some desktops ship with low-power versions of RS-232 ports that are unable to drive port-powered devices or full-length RS-232 cabling. The 232LB9R can amplify these weak signals up to the RS-232 Standard for uses such as running port powered devices. It is also ideal for extending full-powered RS-232 cable runs beyond the typical 50 to 100 feet.
