- Page 7 This module has no power contacts. For field supply to downstream I/O modules, a supply module will be needed. The serial interface module 750-650 and its variations can be used with all couplers/controllers of the WAGO-I/O-SYSTEM 750 (except for the economy types 750-320, -323, -324 and -327).

Requests are indicated by a bit change of state. An assigned bit indicates execution by adopting the value of the request bit.
- Page 14 14 • 750-650 (/xxx-xxx) [Serial Interface RS 232 C] Datatransfer 2.1.1.9.1 Example The module is initialized. The initialization bit in the control byte is set. Output byte 0 Control byte Output byte 2 Output byte 1 0x00 '0000.0100' 0x00 0x00 After the initialization has been executed, the status byte will give back 000.0100.

- Page 17 The presetting is Baud rate: 9600 baud, data bits: 8, Parity: none, stop bits: 1. In this mode of operation the module has the same behavior and also the same process values as the base module 750-650. If another mode of operation is selected by changing the parameters, then the module behaves according to the variation with the selected mode of operation.
