The serial port connections at the back of the module can be 
used to connect an XI582 MMI or, for CPUs with firmware 
version V2.1.0 or newer, a modem or ISDN terminal adapter. 
See section "Remote Communications" on page 43 for more 
information. 
Each XC5010C contains an application submodule that is 
different from the XD505A/XD508 submodule. The sub­
module for the XC5010C contains the C-Bus, L

as well as part of the RAM and flash EPROMs. For infor­
mation on C-Bus baud rates and the bus termination switch, 
see section "C-Bus Termination (Excel 500)" on page 38. 

The operator interface on the front of the computer modules 
allow the Xl581AH/XI582AH Operator Interface or the Xl584 
Operator and Service Computer to be connected. As an 
option, the XI582AH can be connected at the rear of the com­
puter module XC5010C. When connecting to the back of the 
module, the switch on the front panel of the XC5010C must 
be set to "Rear". 

Fig. 53 shows the pin-out of the XP502 Power Supply 
module. 

To monitor the line power supply, the watchdog alarm must 
be provided with its own power or battery supply. 

Controller in operation: 
Watchdog relay terminals 17 and 18 connected. 

Controller non-operational: 
Watchdog relay terminals 16 and 17 connected. 

The Uninterruptable Power Supply XAPU 24-2F contains a 
relay contact and 24 Vac, which can be used for external con­
trols, or for the connection from XP502 terminal A7, A8. In 
case of failure, the relay contacts C and NO are closed and 
the 24 Vac supply is interrupted.
