Quatech CompactFlash Card User’s Manual SSCF-200/300 6. Using the SSCF-200/300 Card 6.1 TERMINATION RS-422 and RS-485 lines should be terminated at the end of the main branch of the receiver with the cables characteristic impedance. These terminating impedances reduce signal reflections at the cable end. It is not necessary to terminate the transmitter end of the cable. The most common method of termination is to install a terminating resistor, typically with a value of 120Ω, at a single receiver.
Quatech CompactFlash Card User’s Manual SSCF-200/300 6.4 RS-422 OPERATION Generally, in RS-422 systems, all 8 signal lines from the DB9 connector are used. Thus 4 twisted pair cables are used, one pair for each of the 4 signals TXD, RXD, RTS and CTS. The RS-422 arrangement allows data to be transmitted and received simultaneously since each signal has its own twisted pair. 6.
