Xantrex Technology XDL 35-5TP manual Command List, Instrument Specific Commands

<WHITE SPACE> is ignored except in command identifiers. e.g. '*C LS' is not equivalent to '*CLS'. <WHITE SPACE> is defined as character codes 00H to 20H inclusive with the exception of the NL character (0AH).

The high bit of all characters is ignored. The commands are case insensitive.

Command List

This section lists all commands and queries implemented in this instrument. The commands are listed in alphabetical order within the function groups.

Note that there are no dependent parameters, coupled parameters, overlapping commands, expression program data elements or compound command program headers; each command is completely executed before the next command is started. All commands are sequential and the operation complete message is generated immediately after execution in all cases.

The following nomenclature is used:

<rmt>	<RESPONSE MESSAGE TERMINATOR>
<nrf>	A number in any format. e.g. 12, 12·00, 1·2 e1 and 120 e-1 are all accepted as the
	number 12. Any number, when received, is converted to the required precision
	consistent with the use then rounded up to obtain the value of the command.
<nr1>	A number with no fractional part, i.e. an integer.
<nr2>	A number in fixed point format e.g. 11·52, 0·78 etc.
<n>	The number of the output or status register to which the command relates.
	Note that <n>= 3 refers to the Auxiliary output.

The commands which begin with a * are those specified by IEEE Std. 488.2 as Common commands. All will function when used on the RS232 interface but some are of little use.

Instrument Specific Commands

For commands specified as 'WITH VERIFY' the Operation Complete message is generated when the parameter being adjusted reaches the required value to within +/-5% or +/-10 counts, whichever is the greater. If the value fails to settle to within these limits within 5 seconds then the Verify Timeout bit (bit 3) is set in the Standard Event Status register and the Operation Complete message will not be generated.

When the supply is operated in LINK mode, commands which set values and ranges are applied to outputs 1 and 2 simultaneously, regardless of the whether <n> is set to 1 or 2. When the command requests verification then verification will be sought from both outputs before the command is completed. Additionally the SAV<n> and RCL<n> commands operate on non-volatile memory reserved for linked mode set-ups and <n> may be set to 1 or 2 with the same effect. Note however that <n> is part of the command header and must be included.

V<n> <nrf>	set	output	<n> to <nrf> Volts
V<n>V <nrf>	set output		<n> to <nrf> Volts with verify
OVP<n> <nrf>	set	output	<n> over voltage protection trip point to <nrf> Volts
I<n> <nrf>	set	output	<n> current limit to <nrf> Amps
OCP<n> <nrf>	set output		<n> over current protection trip point to <nrf> Amps
V<n>?	return the set voltage of output <n>
	– response is V <n> <nr2><rmt> where <nr2> is in Volts
