C584XB/C588XB Converter Box
The C584XB/C588XB box is used to convert RS232 input signal to isolated
RS232, RS422, or RS485 interface, supporting signal ground isolation sys-
tems between the PC and external applications. Two models exist, supporting
four ports (C584XB) or eight ports (C584XB).
Each port of the C584XB has a two-bit DIP switch to set for RS232, RS422, or
RS485. In the C588XB, each port has a one-bit DIP switch to set for RS422 or
RS485. The RS485 mode uses auto data direction functions to maintain no
local echo condition. Users may still need to maintain only one port to output
data. RS485 must be used in half-duplex transmission environment. For
full-duplex transmission environment use RS422.
The C584XB/C588XB boxes have one built-in switching power supply. This
power supply can accept 100-265VAC input or 48--60VDC input (optional).
The C588XB box uses one DB62 to DB62 cable to connect with the C588 card.
The C584XB box uses one DB37 to DB37 cable to connect with the C584
card.
