8.2. Serial Interface and Printer
The instrument has a standard serial port for connecting peripheral equipment.
The serial port is suitable for bi-directional communication. If you transmit ASCII codes of P, Z, T or C letters to
the serial port, the indicator will behave like the related keys have been pressed. If optional serial interfaces are
installed, only continuous data output can be programmed for more than one interface (see chapter 8.2.7 for
setup details).
8.2.1. Standard Serial Interface Connector (RS232C)
The instrument has a standard serial port for connecting to peripherals.
Standard Serial interface; Parameter group [00-]
Baudrate 1200, 2400, 4800, 9600, 19 200, 38 400 or 57 600 baud
Data format 8 bit no parity OR 7 bit even parity OR 7 bit odd parity
Start / Stop bit 1 start bit and 1stop bit
The connection of the standard RS232C of the instrument should be made as given in the table below.
Definition
Desk type housing, panel type
housing; Pin no. (D-Sub, 9-pin, male)
Stainless steel housing
Pin no. (J11 connector)
RS232C;
typical PC allocation
TXD 2 3 3
RXD 3 4 2
GND 7 2 5
Shield Connector body 1
You have to connect each TXD (output) with RXD (input) at the other end.
8.2.2. Optional Serial Interface Connector (RS232C, RS485, 20 mA TTY)
Additional serial interfaces can be added in addition to the standard RS232C port.
2 nd Serial interface Optional RS232C; Parameter group [01-]
3 nd Serial interface Optional RS232C / RS485 / 20 mA TTY current loop* (field changeable); Parameter group [02-]
* 20 mA TTY current loop not available with stainless steel housing
If parameter [012] is set to 2 (= hardware handshake), the second serial interface cannot be used as RS232C
port. Up to 32 instruments can be connected with enabled RS485 port.
