To upgrade the firmware in the module unit pull it out of the frame.  Move the UPGRADE 
jumper into the 

UPGRADE 

position.  Install the Upgrade cable provided (located in the 

vinyl pouch in the front of this manual) onto the SERIAL header J14 at the card edge.  
Re-install the module into the frame.  Run the upgrade as described in the 

Upgrading 

Firmware

 chapter of this manual.  Once the upgrade is completed, remove the module 

from the frame, move the UPGRADE jumper into the 

RUN

 position, remove the upgrade 

cable and re-install the module.  The module is now ready for normal operation. 

 

5.4. 

SELECTING THE GPI PULL-UP VOLTAGE 

The GPI jumpers J4 and J5, located at the rear of the module, selects whether the general purpose 
inputs GPI1 and GPI2 will be pulled up to +5 volts or +12 Volts.  Figure 

 

2-2  shows the jumper 

configuration and the GPI input schematic.  Jumper J5 is used for GPI1 and J4 is used for GPI2. 
 

GPI:

 

To set the pull-up voltage to +5 volts set the jumper to the LO position 

 

To set the pull-up voltage to +12 volts set the jumper to the HI position 

 

5.5. 

Using the GPO OUTPUTS 

There are three pins on the 6 pin terminal strip dedicated to the GPO, NC (Normally Closed), NO 
(Normally Open) and Common, connected as shown in the circuit diagram of section 2.1.  The common 
connection will switch  between NC and NO on a change in state of the RF switch.  This GPO is 
intended to indicate a change in state of the switch.  The signals on NC and NO are to be provided by 
the user.
