Refer to Figure 1. Four RS-232 ports and four RS-232 or RS-485 (two or four wire, send data contol) are standard on the 232D4SS8, depending on the pins you use. Other options and additional RS-422/485 ports are available by contacting B&B technical support. Ports configured as RS-232 support signals TD, RD, RTS, CTS, DTR, and DSR or CD. Refer to Figure 5. Ports configured as RS-422/485 support signals TD and RD only. Refer to Figure 6. The Master port is DTE or DCE configurable. RS-232 ports "A" through "H" are configured as DTE ports. The 232D4SS8 will switch with baud rates from 300 to 38,400 bps, 7 or 8 data bits, even, odd or no parity, and 1 or 2 stop bits. After the switch is made the 232D4SS8 is transparent to data flow. There are nine red indicator LED's on the front of the 232D4SS8. Eight LED's represent ports "A" through "H" and indicate the selected port. The ninth LED...
