loop). Enter into the terminal emulation program. Type some letters and press
the ENTER key. The letters will echo back on the screen if the C-100 is working
properly. See the C-100-A1 Manual for further details.
Problem:
A card number is not transmitted to the programming device when a card is run
through a reader.
Solution:
Check the following:
•
Verify communication from the N-1000 to the programming device.
•
Confirm the panel is not operating in the buffered mode.
•
For readers req5 VDC power (from the control panel), verify voltage at
the reader is +4.9 to +5 VDC.
•
For readers req12 VDC power, verify output of external power supply.
•
Verify card reader wiring. Refer to Section 6 for general card reader wiring
details.
•
Wire the card readers directly to the N-1000 (to eliminate reader to panel
distance). If card reads are then transmitted, the problem is due to
environmental factors.
•
Determine whether the problem is related to the card reader in use or the
N-1000 reader port in use. Wire the card reader in question to an N-1000
reader port that is known to operate properly or wire a card reader known
to operate properly to the reader port in question and test with known card.
Problem:
A keycode is not transmitted to the programming device when entered at an
Eleven-conductor Keypad.
Solution
: Check the following:
•
Verify communication from the N-1000 to the programming device.
•
Confirm the panel is not operating in the buffered mode.
•
Verify the keypad pound (#) key is pressed after entering the keycode. Pressing
the # key is necessary for keycode transmission.
•
To test the operation of an N-1000 keypad port without using a keypad,
simulate keystrokes with a three-way jumper. To simulate a keystroke,
connect one end of the jumper to a row terminal, one end to a column
terminal and momentarily touch the third end to the keypad ground terminal.
See Eleven-Conductor Keypad instructions (Section 6) for 2 of 7 matrix
terminal information.
Example:
Simulate pressing the 4 key.
Connect one end of the jumper to the brown wire terminal (column 1, TB8-1).
Connect the second end of the jumper to the purple wire terminal (row 2, TB8-6).
