Figure 3.7 Configuration using LTC 8712 Series Console Port Expander
On Allegiant systems with a Printer port, up to two Console Port Expanders can be
connected, supporting a total of eight RS-232 model keyboards.
To configure an Allegiant system to operate with an LTC 8712 Console Port Expander, you
must have access to the Allegiant CPU's dipswitches, the PC-based LTC 8059 Master Control
Software, and possibly an Allegiant keyboard.
To convert an Allegiant Console port using a CPU dipswitch method, set dipswitches 3 and 4
to the ON position on CPU dipswitch S1, S100, S1001, or S0201 (the switch number depends
on the Allegiant model being used). After a system reset (power off/on, for example), the
Allegiant's Console port is forced into the Port Expander mode, and the RS-232 data rate is
automatically set to 57,600 baud. To convert an Allegiant Console port via the Master Control
Software, connect to the Allegiant and go online. Select the Parameter tab, and then the
Options tab. Check the box labeled Set Console Port to Port-Expander mode. Download the
table into the Allegiant.
To convert an Allegiant Printer port to operate in the Port Expander mode, first configure the
Printer port to operate as a Console port. This is done by setting dipswitch 4 to the ON
position on CPU dipswitch S2, S101, S1002, or S0202 (the switch number depends on the
Allegiant model being used). After a system reset (power off/on, for example), the Printer port
will begin to operate as a Console port. Next, use either the Allegiant Keyboard User Function
38 or the Master Control Software to change the port to the Port Expander mode. If using the
Master Control Software, connect to the Allegiant and go online. Select the Parameter tab,
and then the Options tab. Check the box labeled Set Printer Port to Port-Expander mode.
Download the table into the Allegiant.
