I/O Features
Transmitting Thickness Data Through an External Device

Note:
The instructions in this chapter apply to all
instruments.
The instrument can communicate with external
devices in several ways. All of these communication
methods rely on the instrument’s I/O port. The
following cables are available for connection to this
RS-232 port (see Figure 3-1 for location):
• USB PC Cable
• Serial PC Cable
• Digital Caliper—Velocity Option
• Li Battery Pack‘s Charging cable
The instrument determines if the cable is connected
to a device provided the device is not “off line” or
“busy”.
Individual thickness readings and A-Scans can be
transmitted to an attached device. With the use of
remote codes, a PC can control the instrument.
In this chapter you will find:
• The byte structure used when thickness readings
are transmitted through the I/O port (Section 6.1)
• Remote commands (Section 6.2)
6.1 Transmitting Data to an
External Device
When below SEND is pressed to transmit a thick-
ness or velocity value through the I/O port, data will
be transmitted at 8 data bits, 1 stop bit, no parity, and
at the user-specified baud rate. The transmitted data
will be in a 13-byte message format, structured as
shown in Table 6-1. Note that data can be transmitted
(and SEND appears) only when the PC cable is con-
nected to a device that can receive data.
