PS200/CH200 12 V Charging Regulators
6.3.3.3 Restore Internal Battery Temperature Measurement
Host command string: RS_INTBT>
PS200/CH200 response string: *OKcc0
where “cc” is a two-character CRC nullifier, and 0 is the string terminator.
See Appendix A.1.2, Write/Reset Remote Battery Temperature RS-232
Programming Example, for a programming example using this instruction.
6.3.3.4 Change Battery Capacity Value in PS200/CH200
Host command string: WR_BC(xx.xx)>
This command sets the battery capacity in Ah, which the PS200/CH200 uses in
its charging algorithm.
PS200/CH200 response string: *Battery capacity = xx.xx
See Appendix A.2.2, Change Battery Capacity RS-232 Programming Example,
for a programming example using this instruction.
6.3.3.5 Enter Battery Test State
Host command string: BATT_TEST>
This command can be used in a datalogger program to test a battery connected
to a PS200/CH200. This command instructs a PS200/CH200 to set its
charging voltage to 11.5 VDC for 90 seconds. Generally, the battery voltage
will be greater than 11.5 VDC, so this command momentarily causes a
PS200/CH200 to stop charging the battery. Then, the datalogger program can
analyze the battery charging capacity (see example program). Because the
BATT_TEST command stays in effect for only 90 seconds, the datalogger
program must issue the BATT_TEST command more frequently than once per
90 seconds for as long as the test is to last.
PS200/CH200 response string: *OKcc0
where “cc” is a two-character CRC nullifier, and 0 is the string terminator.
See Appendix A.3.2, Enter Battery Test State RS-232 Programming Example,
for a programming example using this instruction.
6.3.3.6 Zero Out Qloss
Host command string: RESET_QLOSS>
PS200/CH200 response string: *OKcc0
where “cc” is a two-character CRC nullifier, and 0 is the string terminator.
See Appendix A.4.2, Zero Out QLoss RS-232 Programming Example, for a
programming example using this instruction.
