RS-232 to RS-422 Converter – DB25M to DB25F
- Converts unbalanced RS-232 signals to balanced RS-422 signals
- Data rates up to 90 kbps
- Extends RS-232 line up to 1200 meters (4000 ft)
- RS-422 driver can drive ten RS-422 receivers in parallel (for use in multidrop systems)
- Power supply required (not included, sold separately)
Mode 422LCON, non-isolated RS-232 to RS-422 converter, converts unbalanced RS-232 signals to balanced RS-422 signals. The RS-422 Standard uses a balanced voltage digital interface to allow communications of 90K bits per second on cable lengths of 1200 meters (4000 ft). Ten receivers can be connected to any one driver for use in multi-drop systems.
The RS-232 port is a DB25 male connector with pins 2 (TD input) and 3 (RD output) supported.
Protective Ground (pin 1) and Signal Ground (pin 7) are also connected. The RS-422 port is a DB25 female connector with Send Data outputs on pins 2 and 14, and Receive Data inputs on pins 5 and 17. Protective Ground (pin 1) and Signal Ground (pin 7) are connected through to the RS-232 connector. LEDs indicate Transmit Data and Receive Data.
An external power supply is required (not included, sold separately).
