10 / 99 page áç áç áç áç XRT4500 MULTIPROTOCOL SERIAL NETWORK INTERFACE IC REV. 1.0.7 7 PIN DESCRIPTIONS (CONT.) PIN # Signal DTE MODE DCE MODE TYPE FUNCTION 15 TX5D D_DTR D_DSR I Transmitter 5 – Digital Data Input from Terminal Equipment This input pin accepts a TTL level binary data stream, from the local terminal equipment, and outputs it, in either a V.10, V.11 or V.28 manner, via the TX5A (pin 12) and TX5B (pin 13) output pins. The exact role that this input pin plays depends upon whether the XRT4500 is operating in the DTE or DCE Modes. DTE Mode – Data Terminal Ready (DTR) Input Pin If the XRT4500 is operating in the DTE mode, then this input pin should be tied to the DTR output pin of the terminal equipment. DCE Mode – Data Set Ready (DSR) Input Pin If the XRT4500 is operating in the DCE mode, then this input pin should be tied to the DSR output pin of the terminal equipment. Note: If the XRT4500 has been configured to operate in the “Registered” Mode, then data applied to this input pin will be latched (into the XRT4500) upon the rising edge of the REG_CLK input signal. 16 VPP +12V Power: This supply voltage is internally generated by the Charge Pump Circuit within the XRT4500 device. If +12V is available, then the external components can be eliminated. 17 TX8D D_RL D_RI I Transmitter 8 – Digital Data Input from Terminal Equipment This input accepts a TTL level binary data stream, from the local terminal equipment, and outputs it, in either a V.10 or V.28 man- ner via the TX8O (pin 19) output pin. DCE Mode – Ring Indicator (or Test Mode) Input Pin If the XRT4500 has been configured to operate in the DCE Mode – This input pin should be connected to either the “RI” (Ring Indicator) or the “TM” (Test Mode) indicator output pin of the Terminal Equipment. DTE Mode – Remote Loop-back Indicator Input Pin If the XRT4500 has been configured to operate in the DTE Mode – This input pin should be connected to the “RL” (Remote Loop-back) indicator output pin of the Terminal Equip- ment. Note: If the XRT4500 has been configured to operate in the “Registered” Mode, then data applied to this input pin will be latched (into the XRT4500) upon the rising edge of the REG_CLK input signal. |
