5.2 ELECTRICAL
All figures quoted are typical parameters @ 25°C
ESD PROTECTION: All RS-422/485 signal lines on the SSCF-200/300 card are protected
against electrostatic discharge (ESD)
• >1kv – IEC1000-4-4
UART CLOCK SPEED: x1: UART CLOCK is 1.8432MHz ->115.2KBaud max
x8: UART CLOCK is 14.7456MHz->921.6KBaud max
RS-422 MODE: CTS/RTS flow control signals available.
RS-485 MODE: Auto-tristate of TXD drivers when not transmitting
TERMINATORS: None fitted in card, use an external termination resistor as required.
FAIL-SAFE FEATURE: The receiver inputs include a fail-safe feature that guarantees a logic
high on the receiver when the inputs are open circuit.
