SET UP DEVICE: SERC
BAUD RATE: 2400
LR
DUPLEX: HALF
LINEFEED: OFF
For the 3560 Serial Communication Device the list of parameters includes baud
rate, duplex, and linefeed. Use the
LR
buttons to change the baud rate, if
necessary, and press
ENTER
. Setting the baud rate here also sets the baud rate
of the Serial Printer Device.
The DUPLEX parameter is used to set the duplex or echo mode of the RS-232
communications. Full duplex enables echo so that all characters received are
echoed back to the computer. This is useful when using terminal emulation
software. Half duplex disables echo. This is the usual mode when using control
software on the computer. The duplex mode is changed using the
LR
but-
tons and pressing
ENTER
.
The LINEFEED parameter determines whether or not a linefeed character
(ASCII 0A hex or 10 decimal) is sent at the end of each line of transmission in
addition to a carriage return character (ASCII 0D hex or 13 decimal). Use the
LR
buttons to change the parameter then press
ENTER
.

Commands
The commands used for remote communications are explained in detail in Sec-
tion 5. Commands are available to control nearly every function of the 1560.
For example, the “ROUT:CLOS (@1)” command can be used to select input
channel 1 for measurement. The “INIT:CONT ON” command can be used to
initiate continuous measuring. The “FETC? (@1)” command can be used to
read measurements from input channel 1.

Device Setup Commands
The SYST:MODn:DEVn:READ? and SYST: MODn:DEVn:WRIT commands
(see Sections 6.5.8.19 and 6.5.8.20) can be used to read or set the setup param-
eters for the 3560 Serial Communication Device. The device number of the Se-
rial Communication Device is 2. The module number for the 3560 module is its
position in the stack. For example, if the 1560 has four add-on modules, the
3560 being the last, the module number for the 3560 is 4. Table 32 shows the
