Mode
Sets the 8P-MAS for either Terminal or Modem use. Each time selection 6 Mode is chosen, this setting
toggles.
Terminal Mode
The 8P-MAS does not monitor the connection status of the Master Port. This mode allows an unlimited
number of login attempts. Use this mode for direct cable connections from a PC or Terminal to the
8P-MAS.
Modem Mode
The 8P-MAS monitors the DCD lead from the Master Port. Each time DCD goes high (indicating that a
call has come in) the 8P-MAS generates the Login prompt. Three unsuccessful login attempts causes
the 8P-MAS to hang up the modem. Use this setting when the 8P-MAS is connected to a dial modem.
Timeout
ENTER TIMEOUT =>
The 8P-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 8P-MAS allows local ports to access the Master port by raising RTS or DTR. When the selected
lead goes high on any of the eight 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. The Timeout feature, if enabled continues to operate when Lead control selects a port.
Lead control will only be enabled only when the 8P-MAS is idle. If a caller has logged into the unit or
Manual control is selected, the RTS and DTR leads are ignored. Once a port is selected due to Lead
control, Menu control and Manual control are locked out. The use of RTS (default) 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 Port Control
The manual push-button switch on the front panel can be used for local control of the 8P-MAS. Each
time the button is depressed, the port will cycle to the next port. To return the 8P-MAS to automatic
operation, depress the push-button switch for over two seconds; all Port LEDs will turn off. 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.
When manual control is selected, menu control and lead control are locked out.
