9.10.Boot Loader Operation

The main function of a boot loader is to load or update the firmware to the microcontroller on the Printed Circuit Board (PCB) of an instrument. There are two types of boot loader setup: hardware and software, described in the following sections.

NOTE

When an external MODBUS host device is attempting to communicate with the instrument over the serial or Ethernet port while the instrument is starting up, the instrument may halt. In order to prevent the problem from occurring, ensure that there are no devices attempting communication with the instrument during start-up. Once the sign-on message is displayed on the front panel, it is safe to begin communications.

9.10.1.Boot Loader – Hardware Setup

Verify that the instrument is configured for an RS-232 connection. See Section 8.2 for details on changing the COM port configuration. The instrument can be connected to the PC COM port using a 9-pin serial cable (TAPI P/N WR77).

9.10.2.Boot Loader – Software Setup

Table 9-2 lists the required firmware loader software and firmware options.
