COLD start procedure (software)
While the hardware restart requires physically disconnecting and reconnecting jumpers from the main electronic board,
performing a software restart involves typing in a command in PCCU. If an error was made while typing, begin the procedure
again.
Using PCCU in the terminal mode, type this command exactly as shown: boot=COLD.
WARM start overview
A WARM start does not clear the data stored in RAM. The WARM start will only reset the XRC
any data that has been stored in RAM. A WARM start should be used when taking an XRC
maintenance or troubleshooting. A WARM start can be used when a power or communication interruption caused the XRC
microprocessor to lock-up.
WARM start procedure (Hardware)
NOTE: Pressing the Reset button with the Memory Backup Enable jumper in the enabled position performs a
WARM Start.
Enable memory backup J1 (see Figure 83, Lithium Battery Backup Enable/Disable on page 93), by moving the pin jumper
to pins 1 and 2.
If an external charging source is connected, it must be disconnected. Slide the external battery pack charger, CHGR
INPUT +/- terminal block J17 (see Figure 77: Battery charger and battery pack connections on page 84), from the
XRCG4 board green terminal block.
Disconnect the battery pack connector from the XRC
now out of service.

To place the XRC back in service, connect the battery pack connector J16 (see Figure 77).
Connect the CHGR INPUT +/- terminal block J17 (see Figure 77).
WARM start procedure (software)
Move into Entry mode within PCCU.
Once this has been completed, click the Terminal icon on the PCCU toolbar.
Once the user is in Terminal mode, move to the terminal prompt (->) and type in the following: BOOT=WARM. Press Enter
on the keyboard to initiate the WARM boot.
Troubleshooting communications
Communications overview
These troubleshooting procedures are applicable to all XSeries Remote Controllers with an installed radio. Use Figure 84:
Communication troubleshooting flow chart as an aid for troubleshooting communication problems.
The three basic types of radio communications that can be used between the XRC
–
RS-232 Communications, using a RS-232 module
–
RS-485 Communications, using a RS-485 module
–
RS-422 Communications (available, but not detailed)
The radio/modem may be powered one of two ways: always on or switched. The specific system setup will determine what
steps are needed to power the radio/modem.
When switching power to a radio with Inhibit (SLEEP) mode, the communication 1 port or 2 switched power line will go to the
radio's inhibit (SLEEP) mode input. Power out will go to the radios.
