INTRODUCTION
The EX500 exchange processor is a Crisis Alert Central Exchange. One EX500 with one, two or
three LC500 subscriber cards are mounted in the first RK500 card rack for a capacity of 24 intercom
stations. By adding a RK501 card rack and additional LC500 subscriber cards the capacity can be
increased from 24 to 56 intercom stations.
The EX500 has all of the features of the DXC910 .
The EX500 board includes a two wire data network (RS485) for connection of external annunciators
(DAD104 or DS16), log-printer interface (DNA100), PC interface (DNA100) video switcher interface
(DNA200). This data network has capacity of eight devices. All devices are connected in parallel on
the data pair (star or loop). Each device must be given a different network address (dip switch
programming). The EX500 sets its address on SW2, the DAD104 has the switches (S1) located on the
back, the DNA100 has the switches (SW2) located on the front panel. A typical system may use
address:
08 for the EX500
09 for the first DAD104
0A for the second DAD104
0D for the DNA200
0E for the DNA100 with a log-printer
0F for the DNA100 at the PC
(see the Network manual for setting network address).
The number of call digits are set by SW3 on the EX500 card and the Battery RAM must be reset after
changing number of call digits. All other programming is done from the PC connected to the DNA100.
The PC can run Terminal for Windows 3.11, Hyperterminal for Windows 95/98, Procomm + or any
other emulation software with VT100 emulation.
When the PC is first connected to the DNA100 the Status Display screen will be displayed. Press CTR
X on the PC to go to the main menu and select 6 - COMMUNICATIONS LINK.
You will now be asked for a network address. Enter 08 to program the EX500 or 0D to program the
DNA200. The network will now set up a transparent link to the device that you want to program. See
the appropriate device manual for programming details. Use the SNA command to associate an
intercom station with a DAD104, printer or video monitor. Programming commands may be put in a
text file in the PC and then uploaded to do the programming ( > is the pace character).
