11. PRINTER OPTION
WARNING: THE PRINTER OUTPUT IS NOT
ISOLATED FROM THE BATTERY. THE PRINTER
MUST BE ISOLATED FROM GROUND AND
FROM THE BATTERY TERMINALS. USE AN AC
GROUNDING ADAPTER, NUMBER GCL3-749.
With the RS-232 cable option, a printer can be
connected to the charger (see Function 22 for the
proper baud rate).
If a printer is connected, the
charger will print, at regular intervals of either 15
minutes or 1 hour (see Function 19), the charge data
of the charger and the batteries. The charger data is
printed horizontally in the following order:
1.
NUMBER OF DAYS FROM LAST STARTUP
2.
NUMBER OF HOURS FROM LAST STARTUP
3.
BATTERY VOLTAGE AT THE BATTERY
4.
BATTERY CURRENT
5.
BATTERY TEMPERATURE
6.
AMBIENT TEMPERATURE
7.
OUTPUT VOLTAGE AT THE CHARGER
When an error occurs, the charger will print the error
message and then print a line of charge data. The
charge data is printed so the time of the error is
recorded.
12. TERMINAL OPTION
A terminal may be connected either directly to the
charger or through a modem so the charger can be
operated and the status of the batteries and the
charger can be determined from a remote location.
When the programming mode is accessed through a
terminal, the front panel buttons are disabled.
Almost any terminal can be used to control the
charger output or inquire about its status (Function
22).
WARNING: THE TERMINAL OUTPUT IS NOT
ISOLATED
FROM
TERMINAL OR MODEM MUST BE ISOLATED
FROM GROUND AND FROM THE BATTERY
TERMINALS.
USE
ADAPTER, NUMBER GCL3-749.
To get the attention of the charger from the terminal,
press the return key. The charger will respond with:
OK >
After the OK message is given, the charger enters
the monitor mode and is ready to receive
commands. In the monitor mode, commands have
to be in capital letters and followed by a carriage
return. If the power is interrupted or if the charger is
left in the monitor mode for over three minutes
without issuing any commands, the charger will
automatically exit the monitor mode.
If a password is used when entering the terminal
mode (Function 24), the charger will respond with:

At this point, you have about 20 seconds to enter the
password before the charger returns to the print
mode. From the factory, the password is set to "0"
(this allows automatic entry into the monitor mode),
but it may be changed using Function 24. When
entering the password, enter –9xxx where xxx is the
value that you inserted in Function 24.
NEGATIVE SIGN MUST BE INCLUDED.

However, if an incorrect password is entered, the
charger will return to the print mode. The available

required, the charger will request a NEW VALUE to
be entered. After any item is changed, its new value
is displayed. If a valid command is not entered in
three minutes, the charger will return to the print
mode. When entering data, the entries have to be
scaled because decimal points are not allowed. Use
the following guideline when entering data for each
