Universal interface (Option)
20
PCx[,<baud>,<parity>,<data bits>,<stop bits>,<handshake>,<echo>,<timeout>] - Program Communication
This command adjusts the interfaces. The EPS/MP has a maximum of 3 digital interfaces (x = 1, 2 or 3). The
corresponding commands are
PC1
,
PC2
or
PC3
. Type and number of parameters depend on the type of interface.
Currently there are no settings available for GPIB and LAN. Entering the command without parameter displays present
interface parameters.
Parameter Function
<baud> Baud rate in bps
<parity>
Data parity
O = Odd = Uneven parity
E = Even = Even parity
N = None = No parity bit
<data bits> Number of data bits
<stop bits> Number of stop bits
<handshake>
Handshake
H = Hardware
S = Software
N = None (no handshake)
<echo>
Character echo
E = Echo = echo on
N = None = echo off
<timeout> Timeout in ms when switching between sending and receiving (RS485 only)
Allowed parameters for RS232 interface:
PCx,<baud>,<parity>,<data bits>,<stop bits>,<handshake>,<echo>
Parameter Function
Baud: 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 62500, 115200
Parity: O, E, N
Data bits: 7, 8
Stop bits 1, 2
Handshake: H, S, N
Echo: E, N
Allowed parameters for USB interface:
PCx,<baud>,<parity>,<data bits>,<stop bits>,<handshake>,<echo>
Parameter Function
Baud: 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 62500, 115200
Parity: O, E, N
Data bits: 7, 8
Stop bits 1, 2
Handshake: H, S, N
Echo: E, N
Note: The USB interface of the PC is controlled like a virtual COM port and therefore the parameters correspond to those of the RS232
interface.
Allowed parameters for RS485 interface:
PCx,<baud>,<parity>,<data bits>,<stop bits>,<timeout>
Parameter Function
Baud: 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 62500, 115200
Parity: O, E, N
Data bits: 7, 8
Stop bits 1, 2
Timeout: 0…100
If the interface parameters must be changed permanently, the data has to be saved after the
PCx
command with the
command
<SS>
. No return value.
