Serial I/O Port Cable Connections

Connection to the Serial I/O Port on the laser extensometer is straight forward.

DTR/DSR and RTS/CTS handshaking requirements are not implemented and

only three wires are required for operation. An accessory cable assembly is

available for direct connection to the serial port of an IBM compatible PC. It is

supplied with a standard 9-pin D female connector on one end and a 4-pin RJ11

modular plug on the other. Contact MTS for additional details.

Note See Electrical Connections section for modular jack pin identifications.
