# Printer Settings

To make changes to your printer configuration, connect or work off-line with the desired RTU. Select Devices from the Configuration menu.

In the tabbed dialog box labeled "Device Settings" select the Printer tab:

- Disable – Select this checkbox if a printer will not be used.
- Baud Rate -- Default is 19200 baud.
- Data Bits -- Default is 8.
- Stop Bits -- Default is 1.

Items to Print

RTU Events:

- Session History: prints all session related messages e.g. call-in or call-out sessions
- Configuration Changes: prints all changes made to the Catalyst configuration
- Data Samples: prints a snapshot of all active channels at the specified frequency

Channel Events:

- Alarms: prints messages of channels in alarm state
- Alarm Acknowledgment: prints messages of channels when alarms are acknowledged
- Channel Reset to Normal: prints the messages of channels that transition from acknowledged state back to Normal state.

LDL Flow Control :

This function controls the LDL Flow Control for the specified network. This item applies only when the serial device has a flat ASCII protocol (TTY or LDL) configured. This parameter is only configurable from within Alarmware™.

- Sufficiently long flow control will eventually cause data loss when the internal queues fill up with unprocessed requests. This occurrence is not logged.
- RTS/CTS/DTR is the default and recommended method.
- Trouble-shooting: If you fail to see any printer output:
- Set method to NONE
- Press Normal key. If you see output, you have a cabling problem

XON/XOFF:

- XON character has hex value 0x11, "control-Q," ASCII DC1 character
- XOFF character has hex value 0x13, "control-S," ASCII DC3 character
- It is not possible to reconfigure the XON/XOFF characters
- If an XON is not received within 5 minutes after receiving the XOFF, the port will automatically resume transmission. This prevents permanent freezing of the port should the XON byte be corrupted. It also implies data will be lost if the printer is offline for more than 5 minutes. The RTS/CTS/DTR control method avoids these problems.

RTS/CTS/DTR:

- RACO's VSER-01 cable will work with the KX-P1180 printer
- Printer is considered DTE and the RTU are considered DCE.
- The cable used must have the following properties and the connected printer must be configured consistently (as shown below)
- RJ45 pin 8 -- RXD (from printer to RTU)
- RJ45 pin 7 -- DTR/CTS (from printer to RTU). +12v enables TXD, -12v disables TXD.
- RJ45 pin 6 -- TXD (from RTU to printer)
- RJ45 pin 5 -- RTS (from RTU to printer) +12v when RTU's printer port is enabled
- RJ45 pin 1 -- signal ground

NONE: Unit does no flow control and the receiving device (printer) is responsible for being able to accept the continuous flow of characters at the serial device's data rate.

- Clear All -- The Clear All button returns all parameters to their factory default settings.
- Clear Item -- The Clear Item button restores current field to its factory default setting.
