Serial Ports
RS-232 Connection
Thermo Fisher Scientific
Two serial ports allow daisy chaining so that multiple analyzers may be
linked using one PC serial port.
The standard bi-directional serial interface can be configured for either RS-
232 or RS-485. The serial baud rate is user selectable in firmware for
standard speeds from 1200 to 115200 baud. The user can also set the data
bits, parity, and stop bits. The following protocols are supported:
C-Link
●
MODBUS Slave
●
Gesytec (Bayern-Hessen)
●
Streaming Data
●
The Streaming Data protocol transmits user-selected measurement data via
the serial port in real-time for capture by a serial printer, data logger, or PC.
A null modem (crossed) cable is required when connecting the analyzer to
an IBM-compatible PC. However, a straight cable (one to one) may be
required when connecting the analyzer to other remote devices. As a
general rule, when the connector of the host remote device is female, a
straight cable is required and when the connector is male, a null modem
cable is required.
