The 4-Port Serial Interface SPA provides up to four synchronous serial interfaces. Each port allows a
maximum bandwidth of 8064 Kbps except for the X.21 and EIA/TIA-232 interfaces.
Use EIA/TIA-232 for speeds of 128 kilobits per second (kbps) and below. Use X.21 for speeds less than
2 Mbps. Use EIA/TIA-449, V.35, EIA/TIA-530, or EIA/TIA-530A for higher speeds.
4-Port Serial Interface SPA Cables, Connectors, and Pinouts
The 4-Port Serial Interface SPA uses Smart Serial cable interfaces that support two independent serial
interface ports. The serial end of the Smart Serial cable is a 26-pin connector.
