By default, the subcard works in hardware configuration status and is configured to
RC3000-SUB-D232 mode.

4.14.5 Interfaces

There are four RJ45 interfaces on the RC3000-SUB-RS24.
Figure 4-11 shows PIN definitions of the RJ45 interface on the RC3000-SUB-RS24.

Figure 4-11 PIN definitions of the RJ45 interface on the RC3000-SUB-RS24

The maximum length of the cable used by the RS232 interface is 15 m according to
RS232 standard.
Software configuration status
In software configuration status, each RJ45 interface can be independently configured to
work in RS232, V.24, RS422, or RS485 mode. PIN definitions of the four RJ45 interfaces in
different modes are listed Table 4-21, 0, Table 4-23, and Table 4-24 respectively.
