Off On
(0) (1)
Sw 1: Fast Acquire Mode: 0 = 15 seconds to poll all non-responding devices
1 = 5 seconds to poll all non-responding devices
Sw 2: Disconnect Tolerance: 0 = Disconnect after one failure to respond to a poll
1 = Disconnect after four consecutive poll response failures
Sw 3: Flow Control: 0 = Hardware flow control (CTS/RTS)
(affects both ports) 1 = Software flow control
Sw 4: Poller Enable: 0 = Bus adapter not enabled for polling
1 = Bus adapter is enabled for polling
Sw 65: Host Port B Speed:
00 = 9600 bps; 01 = 38,400 bps; 10 = 115,200 bps; 11 = 230,400 bps
Sw 87: Host Port A Speed: 00 = 9600 bps; 01 = 38,400 bps; 10 = 115,200 bps; 11 = 230,400 bps
Any DIP switch change results in an immediate automatic
reset.
