The baud rate controls the serial interface baud rate, parity bit, data bits and stop bits which can be set to different speeds where 9600,N,8,1 is default in older Boca printers built prior to March 2022. In March 2022 Lemur model printers started to use the R46 logic board (s/n 485250 and higher). This board utilizes the FGL26R## / FGL46R## firmware, on these logic boards the default is 115200,N,8,1.
Please be aware that the baud rate MUST be set the same in both the printer and de PC.
The available speeds are:
| No parity | Even parity | Odd parity |
|---|---|---|
| 1200,N,8,1 | 1200,E,7,1 | 1200,O,7,1 |
| 2400,N,8,1 | 2400,E,7,1 | 2400,O,7,1 |
| 4800,N,8,1 | 4800,E,7,1 | 4800,O,7,1 |
| 9600,N,8,1 (Default on legacy printers) | 9600,E,7,1 | 9600,O,7,1 |
| 19200,N,8,1 | 19200,E,7,1 | 19200,O,7,1 |
| 28800,N,8,1 | 28800,E,7,1 | |
| 38400,N,8,1 | 34800,E,7,1 | |
| 57600,N,8,1 | 57600,E,7,1 | |
| 115200,N,8,1 (Default on current printers) | 115200,E,7,1 |
To change the baud rate via the printer's control panel :
- Make sure the printer is switched on with the ticket correctly loaded. The firmware and fonts version will be visible on the display.
- Depress both the MENU and TEST buttons. Keep both buttons depressed, unit OPERATOR MENU appears in the LCD window or the display starts scrolling through different topics.
- Using the MENU button, scroll down to the “BAUD RATE?” topic. (first topic in the menu, you can scroll backwards using TEST)
- Using the CHOICES button, select your desired speed and parity setting.
- When you are Once you have done this, press the TEST button to confirm.
- The display should show EXIT AND SAVE?; press the TEST button a second time. The printer should reset itself.
If you need to change the print speed on a printer without a display, you can send a command to the printer via the interface. You may use the Boca configuration and test tool from our website, in this program you can use the “Send text” option to send one of the following commands in ASCII format.
BAUD RATE COMMAND - <brx,y,z>
Note: This function should only be used by an experienced user.
This command sets the baud rate (x), parity (y) and data bit size (z) for the printer. Valid values for each are shown below.
For example, to set a 9600 baud rate, even parity, 7 data bits send the <br9600,E,7> command.
| x | y | z | |
|---|---|---|---|
| 1200 | 28800 | N (= no parity) | 8 (= 8 data bits*) |
| 2400 | 38400 | E (= even parity) | 7 (= 7 data bits) |
| 4800 | 57600 | O (= odd parity) | |
| 9600 | 115200 | ||
| 19200 | |||
*Note: At this time, you cannot select 8 data bits with odd or even parity.
