7 – Remote control

7.1 Introduction

PMM ER8000 has been designed to allow remote control operations
through its USB (Rear) port.
A RS232 serial port is also provided for service activities.

7.2 Communication

Half  duplex  communication  is  implemented.  The  RS232  port  has  a  DB-9
female connector and the USB 2.0 has a USB-B connector.
A built-in automatic tool identify the type of communication used.
The communication is at 115200 bit/sec with 8 bit words, one start bit, one
stop bit and no parity
(

115200 N 8 1

).

7.3 Protocol

Be  aware  that  only  the  PC  can  send  the  commands.  PMM  ER8000  will
answer when is inquired only.
The  communication  uses  strings  with  variable  byte  width.  The  characters
used  inside  the  strings  are  in  ASCII  format  (00  -  127)  at 7 bits. The most
significant bits are ignored in reception and set to 0 during transmission.
Every string starts with the special character “#” and stops with “*”.

7.4 Format

Commands are made of ASCII string delimited character “#” (0x23) and the
character “*”(0x2A)
Replies are terminated with <CR><LF> (\r\n)

The following examples are referred, some to the PMM ER8000/00 and
some to the ER8000/01.
