Short description:

Serial or parallel DB25 RS-232 protector (all pins) for any male or female 25-pin port


Tripp Lite's DB25-ALL offers dataline surge suppression for any DB25 serial port, regardless of cable configurations. Connects and protects all 25 pins plus D shell chassis for universal protection of any DB25 application. User configurable for use with male or female captive DB25 port. Convenient DB25 input and output connects directly to the protected port, obtaining a ground outlet from the computer chassis. Surge suppression is handled with balanced arrays of high-speed avalanche diodes that divert excess energies created by electrostatic discharges, faulty wiring or lightning away from network interface connections. Tripp Lite network surge suppressors reduce blown interface connections, garbled transmissions, system lock-ups and hard equipment failure by safely shunting dataline surges to ground.

SUPPRESSION: Reversible DB9 m/f jacks, protects pins 1-25 and chassis, 18V clamping
