How to push RS-232 female to RJ12 connector?

Question

System administration

Good afternoon! The crimping diagram of RS-232 (female) and the RJ12 connector is given, but since I do not know the signals of the Rj12 contacts, the data does not go through the cable, respectively. Who can tell which contact on RJ12 is responsible for which signal
(RxD, TxD, GND)
Here is the cable crimping diagram in the instructions for the equipment

Answer 1

study the pinout of the signals on the RJ12 connector, if provided by the manufacturer.
the name, signal assignment and pinout on the DB-9 are standard.
the use of RJ12 is non-standard.
next time search the Internet for "RS232 cable for EasyLite "
finds something, but I don't know how it works.
