3.2 RS-232 Connection
Note
Refer to the Operating Instructions manual for programming the transmitter using the RS-
232 Interface or see Quick Terminal Mode Setup procedure below.
To use the RS-232 Interface to program the transmitter instead of using the main unit display
you must be familiar with the basics of Si-Ware or another communications program. Most
PC computers provide at least one serial port using either a 9-pin or 25-pin D-type
connector. The port designation can be either COM 1 or COM 2. Usually, when a computer
includes two serial ports, COM 1 will be the 9-pin connector and COM 2 will be the 25-pin
connector; however, port designations can vary. (See Quick Terminal Mode Setup
procedure.)
1. Referring to the schematic below, wire the RS-232 Interface cable.
Note
Many newer Laptop PCs are not equipped with serial ports, having USB ports only.
These PCs will require a USB-to-RS-232 adapter that can be purchased commercially.
2. Connect the cable between the transmitter and the PC using either the 9-pin, 25-pin or
USB-to-RS-232 cable connector, depending upon the port's architecture.
3. Refer to the transmitter Operating instructions manual for details for accessing the
Installation Menu.
