EIA-232 SERIAL PROGRAMMING EXAMPLES
Examples of actual command strings transmissions and typical responses are outlined below.
All commands must be in upper case ASCII, lower case characters are ignored. All commands
transmitted to the AC SUPPLY must terminate with a carriage return <cr> and a line feed <lf>, and
<eos> as will all responses received from the AC SUPPLY.
1. EXAMPLE: Setup a single range AC Source to output 120 V @60 Hz, and close the output relay.
Transmit setup command:
FNC ACS :CHO SET VOLT 120 SET FREQ 60<cr><lf><eos>
Transmit status command to request status response:
STA <cr><lf><eos>
Talk address the AC Source to enable response:
<space><cr><lf><eos> : Positive response indicating status is OK.
F07ACS00 (MOD) ILLEGAL VALUE <cr><lf>: Negative response indicating error condition.
(Typically a negative response would only occur if an error existed in the entry or reception of the
command string, or the values entered were out of range of the AC Source).
Transmit output relay close command:
CLS :CHO <cr><lf><eos>
Transmit status command to request status response:
STA <cr><lf><eos>
Talk address the AC Source to enable response:
<space><cr><lf><eos> : Positive response indicating status is OK.
F07ACS00 (MOD) NO SETUP <cr><lf> : Negative response indicating error condition.
(Negative response would only occur if invalid or no setup string had been transmitted prior to close
command).
2. EXAMPLE: Setup a dual range AC Source to output 30 V on low range @400 Hz.
Transmit setup command:
FNC ACS :CHO SET VOLT 30 SET FREQ 400 SET VLTO <cr><lf><eos>
Transmit status command to request status response:
STA <cr><lf><eos>
Talk adrress the AC Source to enable response:
<space><cr><lf><eos> : Positive response indicating status is OK.
