Solution:
The following comparison between ADAM-4521 and ADAM-4520 is for your reference:
A: Same
1. Converter: RS-232 <==> RS-422/485
2. Data format: 9, 10, 11, 12 bits
3. Power requirement: Unregulated +10 to +30 Volts
4. Power ripple: 200mV, peak to peak
5. 12VDC surge protection and 170 mA overcurrent protection
6. DB9: Female, DTE
7. Support Rx, Tx, GND, RTS
B: Difference
1. Baudrate: 300 - 115.2K for 4521, 1200 - 115.2K for ADAM-4520, besides that, 4ADAM-521 can allow different baudrates between RS-232 and RS-485 interface
