The low capacitance diode array assures that the RS-232 signals will not be degraded by the suppressor. This is in comparison to protectors based on high capacitance TVS diodes. The unit will protect up to eight RS-232 data lines. It will also support two RS-232 lines with no hardware handshaking or one RS-232 line with hardware handshaking. For more complete protection, two units should be used, one on each end of the line.
The compact weather resistant housing features a lockable hinged cover and break-away holes are provided on the rear of the enclosure for mounting. The cable grommet may be adjusted to cable size and is removable.
