Technical Manual Installation & Operation
2.3.2.2 Select Operating Mode
The MX800 can operate in a number of different modes. The primary
alternatives are full duplex, which is the default mode, repeater and simplex.
Using MXTOOLS the operating mode is programmed for each channel.
When a channel is selected in operation the MX800 adopts the mode
programmed for that channel.
The operating mode programmed in the software can be modified by the
settings of DIP switch 2. The functions of this switch are detailed in
Table 2-2 below.
SW 2 Function Description Def

Table 2-2 DIP Switch 2 Settings
Note The Repeater Enable functions as follows:
If the switch is ON and the channel is programmed as a repeater
channel (using MXTOOLS) the MX800 will act as a repeater. If the
switch is OFF the MX800 will remain in full duplex mode even if the
channel is programmed as a repeater. The Simplex Enable operates
in a similar way.
In the case of the Repeater Enable function, the Repeater Enable on
Pin 8 of the DB15 Line connector is effectively in parallel with SW2/4.
If SW2/4 is OFF the function may be controlled through this external
line. JMP 14 selects the control polarity in that case.
