Chapter 9 - DIP-Switch Settings
Switch #5
Enable/Disable Auto-Answer - "Ans"
(Asynchronous Mode/Synchronous Mode/Dial-Up)
In some originate-only applications, you may wish to disable the modem’s automatic answering
capabilities. This may be true if you have a telephone set attached to a modem and wish to receive
voice calls that you yourself would answer instead of the modem. Place DIP-Switch #5 in the UP
position to enable Auto-Answer. Place DIP-Switch #5 in the DOWN position to disable Auto-Answer.
Auto-Answer Enabled = Switch #5 UP
Auto-Answer Disabled = Switch #5 DOWN
(Factory Default Setting = UP)
Switch #5
Originate/Answer Mode
(Asynchronous/Synchronous Mode/Leased Line)
The modem functions in either Originate mode or Answer mode. Place DIP-Switch #5 in the DOWN
position to enable Originate mode. Place DIP-Switch #5 in the UP position to enable Answer mode.
Originate Mode Enabled = Switch #5 DOWN
Answer Mode Enabled = Switch #5 UP
(Factory Default Setting = UP)
Switch #6
Maximum Throughput Setting
(Asynchronous Mode/Leased Line/Dial-Up)
Some applications require you to dial into services with maximum throughput on, and other
applications where maximum throughput must be off (i.e., service not supporting error correction, or
the V.42 handshake interferes with logon sequence). DIP-Switch #6 is used for switching between
these two modes. This DIP-Switch controls three important parameters (error correction, speed
conversion and serial port speed), which in effect enables or disables maximum throughput.
Maximum Throughput Enabled = Switch #6 UP
Maximum Throughput Disabled = Switch #6 DOWN
Factory Default Setting = UP
Switch #6
Slave Clocking
(Synchronous Mode/Leased Line/Dial-Up)
In Synchronous mode, DIP-Switch #6 controls the option of having timing controlled by the receive
clock. The originate modem, in effect, adjusts to the answer (remote) modem. Place DIP-Switch #6 in
the DOWN position to enable Slave Clocking. Place DIP-Switch #6 in the UP position to disable
Slave Clocking.
Slave Clocking Enabled = Switch #6 DOWN
Slave Clocking Disabled = Switch #6 UP
Factory Default Setting = UP
