Table C-4. MVME761 EIA-530 Interconnect Signals

Signal
Mnemonic
Not used.
TxD_A Transmit Data (A). Data to be transmitted; output from DTE to DCE.
Receive Data (A). Data which is demodulated from the receive line; input from
RxD_A
DCE to DTE.
Request to Send (A). Output from DTE to DCE when required to transmit a
RTS_A
message.
Clear to Send (A). Input to DTE from DCE to indicate that message transmission
CTS_A
can begin.
Data Set Ready (A). Input to DTE from DCE to indicate that the DCE is ready to
DSR_A
send or receive data. In DCE conÞguration, always true.
SG Signal Ground. Common return line for all signals.
Data Carrier Detect (A). Receive line signal detector output from DCE to DTE to
DCD_A
indicate that valid data is being transferred to the DTE on the RxD line.
Receive Signal Element TimingÑDCE (B). Control signal that clocks input
RxC_B
data.
Data Carrier Detect (B). Receive line signal detector output from DCE to DTE to
DCD_B
indicate that valid data is being transferred to the DTE on the RxD line.
Transmit Signal Element TimingÑDTE (B). Control signal that clocks output
TxCO_B
data.
Transmit Signal Element TimingÑDCE (B). Control signal that clocks input
TxC_B
data.
Clear to Send (B). Input to DTE from DCE to indicate that message transmission
CTS_B
can begin.
TxD_B Transmit Data (B). Data to be transmitted; output from DTE to DCE.
Transmit Signal Element TimingÑDCE (A). Control signal that clocks input
TxC_A
data.
Receive Data (B). Data which is demodulated from the receive line; input from
RxD_B
DCE to DTE.
Receive Signal Element TimingÑDCE (A). Control signal that clocks input
RxC_A
data.
Request to Send (B). Output from DTE to DCE when required to transmit a
RTS_B
message.
Local Loopback (A). Reroutes signal within local DCE. In DTE configuration,
LL_A
always tied inactive and driven false. In DCE conÞguration, ignored
Data Terminal Ready (A). Output from DTE to DCE indicating that the DTE is
DTR_A
ready to send or receive data.
Remote Loopback (A). Reroutes signal within remote DCE. In DTE
RL_A conÞguration, always tied inactive and driven false. In DCE conÞguration,
ignored.
