2.4 Wiring method

The I-7530, I-7530-FT and tM-7530 are RS-232 data communication modules, and
the RS-232 interface uses a D-Sub 9-pin female terminal. The below picture will
describe the wiring between the PC and the module.

The UART communication port of the I-7530A has three interfaces with RS-232,
RS-485 and RS-422, and the three interfaces cannot be used at the same time. The
below figure shows the wiring method for connecting the I -7530A to other UART
devices. When using the RS-485 or RS-422 interface, we recommend using twisted pair
cables as the communication medium.
