Model 232SP9 protects RS-232 ports from damage caused by large voltage peaks

from lightning and other power problems.The surge protector uses 600W Transient

Voltage Suppressors to protect all 9 pins. It has one DB9 male and one DB9 female

connector with all 9 pins passing straight through. The TVSs are connected between

the ground screw and pins 1, 2, 3, 4, 5, 6, 7, 8 and 9. The 232SP9 will suppress any

voltage levels above 12 Volts without affecting the normal RS-232 data.

Model 232SP9 is placed inline, between the data cable and the RS-232 port, as

close to the protected port as possible. The ground screw must be connected to earth

ground. A minimum of 12 AWG copper wire is recommended. Model CU15B is a

copper grouping strap, cut to length, for ground connections that are longer than a few

feet (one meter). If this device is not properly grounded, it will not protect RS-232 lines.
