1.3 RS-232 Modular Adaptors and Cables

RS-232 modular adaptors are available from Equinox to convert RJ-45 modular jacks to DB-25 or DB-9 connectors. These modular adaptors, used with the 10-wire reversing modular cables, perform the same functions as shown in Figures 3 through 5. Figure 6 shows the RS-232 modular adaptors available from Equinox.
