Baud Rate
The AC8 must be set to the same baud rate as the modem and the Optomux network. The default baud rate is 1200 baud.

can be used by a modem to determine if an AC8 is connected and operating.
The delay jumpers (Figure 3, set the delay from the Clear To Send (CTS) line to the beginning of data transmission (TXD). For most
The baud rate jumper (Figure 3) determines the baud rate of the AC8. Selectable baud rates are: 300, 600, 1200, 2400, 4800, and 9600.
This group of jumpers (Figure 4) configures the RS-232 interface (DTR, DSR, CTS, and DCD). The default jumper settings are to install
The DTR jumper should be installed if your modem expects this signal. If the jumper is installed, the signal is always true. This signal
