Side Connector Panel
The side connector panel is protected from rain by a tethered plug that is
attached to the holster. This panel has the following components, which are
identified in Figure 2-1:
•
RS-232 port (item A)
A nine-pin male D-Sub connector with locking nuts. The RS-232 port and
the supplied RS-232 cable are needed when you download programs from
a PC to the tester and when you control the tester remotely from a PC.
With a printer cable connected, the RS-232 port enables you to print serial
data. This port also controls the optional 990-GM/2 and 990-GM/V
Golden Modem appliqués.
•
DC power jack (item B)
A barrel jack that is used to power the tester externally and charge the
battery. This jack accepts a 12-15 VDC center-positive voltage that is
provided either by the supplied AC power supply or by the optional
Vehicle Power Cord.
•
Charging status LED (C)
A bicolor (red and green) LED that indicates the charging status of the
internal battery pack (see "Charging the Battery" for details).
