A DB25 male connector is used on the TTL side and a DB25 female
connector is used on the RS-422/EIA-530 side. The converter supports RD,
TD, RTS, and CTS. Pin 7 is signal ground for both connectors.
ACCESSORIES
SMI6-12-V-P230-C1 - Power Supply, 12 VDC 6 Watt, 2.5MM Plug, International AC Input,
International AC Blades
The converter supports baud rates up to 115.2 kbps. Open pads are
provided for each line. If desired, you can change the pin connectors for
any of the 4 channels. When converting a second RS-422 channel, use the
corresponding RTS A and RTS B pins (refer to the Quick Start Guide).
232CAMS - DB25 male to DB9 female adapter cable, 15.24 cm (6 in)
The converter inverts the TTL signal. Refer to the specifications table to
determine polarity. An external +12 VDC power supply is required (not
included).
