Timeout
ENTER TIMEOUT =>
The 4P-MAS can automatically de-select a port if no data activity is detected received by the Master
Port. This setting selects the length of time 0-99 minutes for this timeout. The Factory Default setting
of 0 selects No Timeout.
Exit
Exit the programming menu and activate all current settings. If the baud rate and/or character format
have been changed, Exit will enable those changes.
LEAD CONTROL
The 4P-MAS allows local ports to access the Master port by raising RTS or DTR. When the selected
lead goes high on any of the four ports, it will establish a connection from that port to the Master Port.
This works on a queued basis; as subsequent ports each raise their lead they will be serviced in order
of appearance. Lead control will only be enabled only when the 4P-MAS is idle. If a caller has logged
into the unit or Manual control is selected, the RTS and DTR leads are ignored. The Timeout feature, if
enabled continues to operate when Lead control selects a port. Once a port is selected due to Lead
control, Menu control and Manual control are locked out. The use of RTS or DTR is selected on a port
by port basis using jumper selections on the printed circuit board. See page 6 for configuration details.
MANUAL CONTROL
The manual push-button switch on the front panel can be used for local control of the 4P-MAS. Each
time the button is depressed, the port will cycle to the next port. To return the 4P-MAS to automatic
operation, depress the push-button switch for over two seconds; all Port LEDs will turn off. Manual
control will only be enabled only when the 4P-MAS is idle. If a caller has logged into the unit or Lead
control is selected, the front panel switch ignored. The Timeout feature, if enabled continues to operate
when Manual control is established. To override this feature, select Timeout = 0 from the Local
Configuration menu.
