Model 8P-MAS

Page 5

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.
