| Most SAT-B terminals has a synchronous RS232 High Speed data interface port. Because RS232 is an unbalanced technology it is relative sensitive to induced noise into cabling. If relative long cables are used this could derate the quality of the established link. ROP25 has builtin fibre optic modems and therefore cabling is replaced with fibre optic cables which eliminate this problem. Alternative RVP-NET can be used, as cabling to this device is made via LAN. |
