SPECIFICATIONS

As of the date this Instruction Data Sheet was published, the following specifications apply to the RFL NCM Module. Because all of RFL products undergo constant improvement and refinement, these specifications are subject to change without notice.

Live Insertion/Extraction: The NCM Module is capable of live insertion and extraction into the IMUX 2000 shelf without interruption to the DS1 or any other DS0.

Asynchronous Data Interface: Full duplex or half duplex, one channel operation, one or two data ports.

Data Rate: 2400, 4800, 9600, 19.2kbps and *38.4kbps. (*38.4kbps may require character pacing and/or additional stop-bits)

Start-Stop Distortion: Referenced to actual Rx Baud <9%

Gross Start-Stop Distortion: Referenced to nominal Baud <50%

Character Delay: 16 characters max (delay is dependant on input frequency deviation from nominal data rate)

Frequency Deviation: Allowable input Frequency Deviation from nominal data rate is ±4%. (Stop bit reduction is used to compensate for frequencies greater than local oscillator generated baud).

NMS Mode ASCII Character Addressing Format: [0-9][0-9][0-9] [:]

Example: NMS sends “215:”

Time Slots: Occupies one selectable DS0 time slot.

Jitter: Excluding Stop bit <1%

Rogue Detectors: One minute pick-up, two minute drop-out

RS-232 DCE Interface:

Supports: Tx Data, Rx Data, and Signal Ground. Receive Line Signal Detect and Clear to Send are always held active.

RS-485 DCE Interface:

Two-wire: Supports half-duplex, transmit data or receive data, and ground.

Four-wire: Supports full-duplex transmit data, receive data, and ground.

Telnet Interface: Supports: Tx Data and Rx Data over ethernet.

Connector:

For RS-232 the NCM module uses an MA-402I Module Adapter, which provides two DB-9 female connectors.

For RS-485 the NCM module uses an MA-485 Module Adapter, which provides a single, six position terminal block.

For Telnet the NCM module uses a shielded RJ45 connector.

Power Dissipation: 0.5 Watt nominal

MTBF (Calculated): TBD

Operating Temperature: -20oC to +55oC (-4oF to +131oF).

Humidity: 0 to 95 %, non-condensing.
