26 GOSSEN-METRAWATT
With the following telegram, the SECUTEST PSI acknowledges whether it has executed an instruction
(Y=Yes) or not (N=No). An acknowledgement, for example, is also made when a reply message is not
required:
Acknowledge: Instruction executed, transmission format:
Y<ADRESSE><DELIMITER$><CHKSUM> <CR>
Not-Acknowledge: Instruction not executed, transmission format:
N<ADRESSE><DELIMITER$><CHKSUM> <CR>
9.2 Instruction set, validity and syntax
The syntax checker in the tester checks only the first three characters of each instruction. If they are
correct, the instruction is accepted.
Parameters and instructions are configured in such a way that there will be no ambiguities. Writing in
uppercase or lowercase letters is of no importance. At any rate, the checksum can only be obtained
from the actually sent characters.
The parameter x is the address of the device (SECUTEST 0701S or SECUTEST PSI) which is to be
addressed. If only one equipment is connected, an address need not be given.
Address range: 0
≤ x ≤ 90
