ES601Plus OPERATING MANUAL
7.2 Connections
For computer control, connect the PC to the RS232 serial port of ES601Plus. The RS232 connector
of ES601Plus is DB9 female, which is compatible with USB-to-Serial converter cables. For
connection to a physical COM Port at the PC, use a standard DB9F-DB9M serial cable. Do not use
a NULL-modem cable for this connection. A suitable serial cable is available from Datrend Systems
as Part Number 3140-010.
7.3 Communication Settings
To prepare ES601Plus for computer control, from MANUAL or AUTO MODE menu select
SYSTEM SETTINGS ' COMPUTER INTERFACE ' RS232 MODE.
At the PC, the required COM Port or VCP settings are:
19200 baud, No parity, 8 data bits, 1 stop bit (19200,N,8,1)
Note that for computer control, the baud rate (19200) is not the same as that used for printing Test
Record reports via the ES601Plus serial port.
No handshaking is required and should be disabled in the PC COM setup.
7.4 Protocol
7.4.1 General Format of Data
Commands and data are conveyed as strings of ASCII text. The carriage return character (\r, or
0x0D in hexadecimal) terminates PC commands and measurement data returned by ES601Plus.
Upon conclusion of the safety test sequence, the last character sent by ES601Plus is form feed (\f,
or 0x0C), which terminates the "END" message. ES601Plus also sends a form feed \f as the last
character of a Test Report download. Optionally, user software may detect form feed \f as an event
marker in the ES601Plus data stream.
