Troubleshooting " Printer Offline"

1. Check for voltage on DSR Term to GND on the TB4. The printer should hold this voltage high (+8vdc) when 'Ready to Print'.

2.

If the printer is not ready/offline the Printer pulls this voltage down to -8vdc. Check for pin 20 on the RS232 Cable from the

printer. This should be +8vdc or more, pin 7 is Ground. During an "Offline" condition the printer will pull this to -8vdc.

SECTION 4: INSTALLING THE CONTROL

NOTES:

• J9 and VT-SERCBL can be used for Printer output, but it does not

monitor DSR voltage and printer will always show "Printer Off-

Line".

• The DSR terminal of TB4 would have to be shorted to +12VDC to

clear printer trouble.

Voltages

TXD to Ground sits at -11.65vdc then pulses to +4vdc while printing.

(Use code #61 to print log)

NOTES:

•

The cable between the Panel and the Automation PC is 50 ft.

maximum. Shielded Cat 5 wire is recommended.

•

The connected PC must be capable of receiving continuous

9600-baud data.

Testing the Transmit and Receive data at the Panel:

Receive:

On TB4 meter between RXD Terminal and GND Terminal

With no data transmitting it should sit idle at approximately -5 to -

11VDC. It should quickly pulse when Automation is transmitting

the data.

If this voltage exists the Automation is sending data out.

Transmit:

On TB4 meter between TXD Terminal and GND Terminal with no data

transmitting it should sit idle at approximately -5 to -11VDC. When

the panel is transmitting data the voltage will quickly pulse. If this

voltage exists then we know that the panel is sending data out.
