d. If that does not resolve the issue, replace the MSR or terminal.
e.
If MSR is just intermittent, try cleaning the MSR by using a card wrapping in a cleaning cloth
with cleaning solution (ie. paper towel sprayed and then wrapped around a card)
Warning! The OS on the P1220 is typically Windows XP. There is a known issue with Windows XP when
cold/hard booting which can make the P1220 inoperable and require replacement due to operating system
corruption. Use the On/Off button on the P1220 BEFORE unplugging the terminal. Only power down or
unplug the P1220 as a last resort.

Are the serial ports working?
Using Hyperterminal to test COM ports on Radiant Systems POS systems. Basic instructions:
1)
Cabling: For Radiant Systems RJ-type ports, you can communicate between ports using any of the
standard RJ cables that ship with our products. These cables have a 'half-twist' so that all outbound signals will
automatically be routed to the appropriate inputs on the other side. (RJ ports are the ones using the standard
telecom modular plugs with the locking tabs).
For standard DB-9 ports, a null modem cable must be used. This is a cable that swaps all of the signal pairs
and has a female DB-9 connector on each end. Alternately, if you have a DB-9 to RJ adapter such as CN00322
you can connect a DB-9 port to an RJ-type port or two DB-9 ports together. See RJ_End diagram for details on
pinouts.

2)
Start the Hyperterminal program. If you cannot find a shortcut in the Start Menu / Programs
/Accessories / Communication, use Explorer and look for hypertrm.exe in C:\Program Files\Windows NT.
3)
The program will have several prompts, some will only appear the first time you run the program:
a.
Make hyperterminal the default telnet program.
b. Specify any area code you wish – the program insists on having this information.
c.
Just hit OK on prompt to select a location...use 'My Location.'
d. If prompted to install a modem, click 'No.'
e.
Enter a connection name – 'COM' is restricted but 'Comm1' 'Comm2' etc are not.
f.
Set equal bits per second, etc. Make sure you use the same 'Flow Control' on each –
'None' might be the best choice.
