Note: In order for changes to the dip switch configuration to take effect, the printer power
must be reset. This action occurs automatically when the battery is removed to gain access
to the dip switches.
3.3 Communications
The ANDES 3 Printer is able to support two modes of communication simultaneously –
Either RS232 and IrDA (If Dip switch #1 is ON) or RS232 and 802.11b or Bluetooth ™
(If Dip switch #1 is OFF and Dip Switch #2 is ON).
Dip Switch #2 is used to control the RS232 Port. If the Switch is turned ON the RS232
port is disabled and if it is turned OFF the RS232 Port is enabled. If RS232 interface is
not required, disabling the port will save battery power.
Bluetooth or 802.11 RF communications is available if optional daughter boards are
installed. The printer can have either Bluetooth or 802.11 enabled but not both of
them at the same time.
3.3.1 Serial Communications specification
The RS232C Interface signals for the ANDES 3 Series printers are terminated on a 6
PIN RJ type data connector located on the side of the printer.
Six connections are provided from the Serial Interface to the host computer. The
Table 3 below lists the Serial Interface signals and pin outs on the RJ connector and
the connector pin locations are shown in Figure 13.
A minimum of two connections are required for operation: RXD – pin 3 and Common –
pin 1
Note: The communication Parameters: Baud rate, Data Bit and Parity must be set same as
the host device settings.
