User Manual, Ver. 1.3, Apr. 2018, Page: 63

6.3 Application 3

Addressable RS-232 Controller (Dual-channel)



Each tM-7522 module has a unique address



Each tM-7522 module can support two RS-232 devices, AA and AA+1.



The Host PC first sends a command to each tM-7522 modules one-by-one.



The destination tM-752N module will pass the command to its local RS-232 device 1 or
RS-232 device 2.



The tM-752N module then sends the response from the RS-232 device back to the Host
PC.



The RS-232 device can be used for command (Application 1) or null command
(Application 2) type controller applications.
