Surge suppression option 

Surge suppressor is applied to each line; capable of sustaining up to 

40-A peak, 8 x 20-µs transient surges, a clamping voltage of 30 V (RS-

232) or 15.5 V (RS-422/485), and a peak energy dissipation of 0.1 

Joules.  
Note: Units with the "SS" option are limited to 115.2 kbps due to 

capacitive loading.
