Serial Communications Interface
The modem communicates with the controller using the Data Interface
Port connection interface. The protocol supported over this link is the
Native Control Language (NCL). The data format for NCL is: 8 data
bits, no parity, 1 stop bit.
The serial interface lines (RXD, TXD, DCD, DTR, DSR, RTS, CTS,
RI) are TTL compatible. They are fitted with a 33Ù series resistor and
clamp diode to the internal supply line for protection. The electrical
interface capability of these signals is as follows:
Input Voltage Range 0 – 3.3V or 0 - 5V
Output Voltage Range 0 - 3.3V
Current Source/Sink ± 3mA (maximum)
The operation and active condition of these lines is summarized below.
