COML 2232F

4.2 ELECTRICAL

All figures quoted are typical parameters @ 25°C (77°F)

RS-232 SIGNALS: Typical output level ±5.5V (open circuit voltages) TX, RX, CTS and RTS are supported on each port

UART CLOCK SPEED: 1.8432MHz, max baud rate 115.2K bps

ISOLATION:Isolation is defined between ISOGND and host 0V supply (metal case of card and cable shield braid) and can be up to +/-50V, DC to 60Hz. The two ports share a common ground (ISOGND): no isolation exists between the two ports

SCAVENGED POWER: The isolation driver circuit will only supply enough power to guarantee correct RS-232 signal operation into 3K-ohm loads on TX and RTS. Using terminal equipment that scavenges power from the RS-232 signals may not work

UNUSED SIGNALS: If RX or CTS inputs are not used, make sure they are looped back into TX and RTS respectively to prevent them from floating
