Before you begin, be sure you have the following: 12 VDC Power Supply, 6 W, Int’l AC Input, 2.5mm Plug + 422CEC Serial Converter # SMI6-12-V-P230-C1 + 12 VDC Power Supply (sold separately) Serial Adapter Cable, DB9F to DB25M, 6 ft (1.8m)
The RS-422 driver has the ability to drive 10 RS-422 receivers connected in parallel. A system of multiple 422CEC converters. This allows you to extend your receivers may require some experimentation with RS-232 line up to 4000 feet. If you do not require all the RS-232 DB25 resistors, line lengths, grounding, etc.
Need help?
Do you have a question about the 422CEC and is the answer not in the manual?
