Signal Name | Pin # | I/O | Description |
SD | 2 | O | Sending Data |
RD | 3 | I | Recieving Data |
RTS | 4 | O | Request To Send: This Signal is set to on when the NC starts sending data and is turned off when the transmission ends. |
CTS | 5 | I | Clear To Send: When this signal and the DSR signal are set high, the NC can send data from SD. If this signal is set low the NC will stop sending data after two more characters are sent. Jump 5 to 4 if signal isn't used. |
DSR | 6 | I | Data Set Ready: When the external device is ready to operate to needs to set this signal high. If this signal goes low anytime during data transfer, NC alarm 86 will occur. Jump 6 to 20 if signal isn't used. |
SG | 7 | - | Signal Ground |
CD | 8 | I | Carrier Detect: Signal must be straped to DTR. Jump 8 to 20 in cable. |
DTR | 20 | O | Data Terminal Ready: This Signal is set to on when the NC is ready for operation. |
FG | 1 | - | Frame Ground: This electrically connects the NC cabinet ground to your extirnal device's ground. Note: If grounds are of a different potential between devices, damage to equipment and/or electric shock can occure. Be sure all equipment is properly grounded! |
