Page 10: Functional Description
ODW-720-F1 is a fibre optic modem that converts between electrical RS-232 and a fibre optic link. ODW-720-F1 can also be used to convert from RS-232 to RS-485 by using one ODW- 720-F1 and one ODW-730-F1. Data rate up to 250 kbit/s ODW-720-F1 converts data using rates from 300 bit/s up to 250 kbit/s. -
