File name RS232 null modem.pdf CableEye Wiring Report Name: 3 DB9F-DB9F-S7X MATCH DATA DB9 NULL MODEM 7-6-03 12:18 PM Print your company information here. Set up in Preferences / Print Options. Socket L DB9 Female SH 1 2 3 4 5 6 7 8 Socket R DB9 Female SH 6 7 8 1 2 3 4 5 NETLIST L-SH L-1 L-2 L-3 L-4 L-5 L-6 L-8 R-SH L-7 R-8 R-3 R-2 R-6 R-5 R-4 R-1 R-7 NOTES DB9 NULL MODEM Use this female-to-female cable in any application where you wish to connect two DTE devices (for example, two computers). A male-to-male equivalent of this cable would be used to connect two DCE devices. The cable shown below is intended for RS232 asynchronous communications (most PC-based systems). If you are using synchronous communications, the null modem will have additional connections for timing signals, and a DB25 connector would be necessary. NOTE: Not all null modem cables connect handshaking lines the same way. In this cable, Request-to-Send (RTS, pin 7) asserts the Carrier Detect (pin 1) on the same side and the Clear-to-Send (CTS, pin 8) on the other side of the cable. This device may also be available in the form of an adapter. CableEyeTM by CAMI Research Inc. Conductivity Threshold: 2 Isolation Threshold: 5 M |
