Timeclock polling errors and suggested solutions

This is a list of error codes from polling the time clock and suggested solutions. First is the error code, then the fault description, then a list of recommended solutions.

Error Codes, Fault Description and Recommended Solutions

0: No error has occurred.

1: No data has been received from the clock. The clock is not responding.

Check clock has power and is operating correctly.
Check RS485 converter has power (if used).
Check correct Baud Rate on Clock and PC.
Check correct station numbers set.
Check connection wiring.

2: The PC software has detected a data error.

Check correct Baud Rates on Clock and PC.
Check communication line for excessive length, especially on RS232.
Check communication line is not in close proximity to electrical noise, e.g. arc welders, power cables, etc.
If using RS232, then you may have to convert to using RS485 if the problem persists.
If using RS485, then check 120 ohm terminating resistor.
If using RS485, then use shielded twisted-pair cable with shield connected to ground at converter end only.

3: The wrong station replied.

Turn power off to Clock for at least 30 seconds and retry.

4: The clock received a data error.

Same as error 2.

5: The clock polled was busy. Retry later.

Clock is in use and cannot be polled. Poll again at a later time.

6: The clock has processed the wrong command. The clock must verify the command sent to it in it's reply.

Same as error 3.

7: Data has been received but no end of packet was received.

Check that there are no computer TSRs/Windows applications/Network/Interrupt conflicts with the polling software. The polling software must have exclusive use of the com port interrupt selected.
Check communication line is not in close proximity to electrical noise, e.g. arc welders, power cables, etc.
Check RS485 converter is not faulty (if used).

8: A disk write error was detected when storing data.

Check computer has enough disk space.
Check computer disk is not faulty.

9: Disk file could not be opened.

Same as error 8.

10: PC serial port transmitter error. The clock may not be connected.

Check that clock/RS485 converter is connected to the correct port.
Check that RS485 converter has power.
Check wiring to PC port. Pins 6 and 8 on DB9/pins 5 and 6 on DB25 connectors must be connected from the clock/RS485 converter, otherwise this error will occur. See wiring diagrams.
Check PC serial port is not faulty.

11: Data received from the clock may contain errors. A memory checksum error was detected by the clock.

Clock data has been corrupted but can possibly be used if edited correctly. There may only be a small portion of data corrupted and the majority of the data may be error free. Use data with caution.

12: The command file is not properly formatted.

Check that the command file conforms to the correct format (refer command file documentation).
Line number containing error will also be displayed with this error.

13: The modem has made connection with the remote modem.

Not used.

14: There is no reply from the modem when initialising.

Check that the modem is plugged into PC port.
Check modem is switched on.
Check modem is on correct port.
Check modem initialisation string.
Check modem RS232 connections.

15: Modem has detected an incoming call.

Not used.

16: No carrier has been detected from the remote modem.

Check that dial out number is correct in command file/clock setup.
Check local and remote modems are compatible.
Check remote modem is on.
Check that moth local and remote modems initialised correctly and that they are in the same operating mode.

17: An error has occurred when talking to the local modem.

Check that the correct commands have been sent to the modem.
Check that the initialisation string is formatted correctly for the modem in use.

18: The modem has not detected a dial tone when it tried to dial out.

Check phone line connection.

19: The number dialed was busy.

Number dialed was engaged. Try again later.

20: The local modem did not receive an answer from the remote modem.

Check that both modems are compatible with one another and that they are both setup with the same mode of operation and baud rate.
Possibly also ensure that the "AA" light has come on at the remote modem - if not, then turn modem off and back on then clock off and back on.

21: An error in the local modem initialisation file was detected.

Check modem initialisation string. See modem string format notes (elsewhere).
Line number with error will be displayed with this error.

22: A file format error in the data input file was detected.

The data file being loaded to the clock (e.g. bell tables) does not conform to the correct format. See appropriate documentation for correct data file format.
Line number with error will also be displayed with this error.
