Power Supply
The A52/A53 converters are designed for st24 VDC unregulated
power for use in industrial environments. Operation is guaranteed when
using any power supply b9 and +30 VDC at 350 mA. An optional
power adaptor (9 V 1.5 A UL 110/230 V) can support up to 4 converters
(see the following diagram).

NOTE
Each group of (DTR, DSR) pins are shorted, freeing users from
the hardware flow control cable wiring problem. For this reason,
we list two types of RS-232 cable wiring below.
Type 1: To connect the RS-232 side of A52/A53 to a DTE (e.g., PC
COM1/2) or DCE. (Be sure to check the precise DTE/DCE
pinouts. The following DTE/DCE pinouts are just an example.)
