The SEL-3390S8 serial adapter card comes with standard PCIe x1 edge connector and RIG-B time synchronization for the SEL-3355 computer. Each serial port provides up to 921 Kbps data rates, +5 Vdc port power, and IRIG-B synchronization signals. The RJ45 to DB-9 adapter cables allow for up to six EIA-232/-485/-422 multidrop connections per card. Up to four SEL-3390S8 serial adapters can be added to each SEL-3355 Computer.

The EL-3390E4 four-port Gigabit Ethernet card comes with standard PCIe x4 edge connector and four independent 10/100/1000 Mbps Ethernet ports for connecting up to four different networks. The EL-3390E4 has copper and fiber-optic connections which include 4 RJ45 copper ports, 4 LC small form-factor pluggable (SFP) fiber-optic ports, or 2 RJ45 and 2 SFP ports. Up to two SEL-3390E4 cards can be added to each SEL-3355 computer.
