MICROPROCESSOR INTERFACE
5.1 INTERFACE METHODS
There are five methods for interfacing with the Advance
microprocessor;
1. Operator Interface - using the keypad.
2. Technician Interface - using the configuration jump-
er.
3. PC Mode - using the PC Mode jumper.
4. PC Card - Transferring data using a PC Card
5. ReeferManager & Reports - Access using a com-
puter
Operator Interface such as start, stop, Pretrip, reading
alarms, reading data and changing Functional
Parameters may all be performed using the Keypad
(refer to Section 3).
Technician Interface and PC Mode require the use of an
additional connector before any actions may be
performed and each allows increased interaction,
including operations that may be performed with the
microprocessor powered while the unit is shutdown.

5.2 TECHNICIAN INTERFACE
(REMOVE JUMPER MODE)
The Technician Interface Mode allows the technician to
change Configurations, test the unit components and/or
service the refrigeration system. To place the
microprocessor in the Technicians Interface Mode:
a. Place the Main Power switch in the OFF position.
b. Locate the serial download port (item 14, Figure 2−3)
remove the protective plug to gain access to the wire
terminals.
c. Plug in a Configuration Jumper or install an insulated
jumper (see Figure 5−1).
NOTE
For units equipped with a switch labeled
ENGINE/OFF/STANDBY (DOES):
The DOES may be placed in either the ENGINE
or STANDBY position to enter the technician in-
terface mode. If actual operation of the high
voltage components (i. e. the evaporator fan
motor) is desired, the power plug is to be con-
nected and then the DOES is to be placed in the
STANDBY position when entering the techni-
cian interface mode.
For units equipped with a switch labeled
START/RUN-OFF (SROS):
The switch labeled STANDBY/ENGINE (DES)
may be placed in either the ENGINE or
STANDBY position to enter the technician inter-
face mode. If actual operation of the high
voltage components (i. e. the evaporator fan
motor) is desired, the power plug is to be con-
nected, the DES is to be placed in the
STANDBY position and then the SROS is to be
placed in the START/RUN position when enter-
ing the technician interface mode.
d. Place the Main Power switch in the desired position.
The alarm LED will come on, the setpoint will display,
but the refrigerated compartment temperature will
not, and “REMOVE JUMPER” will display for 10
seconds. Remove the Configuration Jumper or insu-
lated jumper at this time. The MessageCenter will
then display “ ↑ ↓ TO SCROLL, THEN = TO SELECT”
for 10 seconds.
e. Press the UP ARROW Key to scroll through the Menu
beginning at the top.
Press the DOWN ARROW Key to scroll through the
Menu beginning at the bottom.
f. Select the Mode you wish to access,
Configuration Mode
Component Test Mode
Service Mode
and press the “=” key. Information on these test
modes is provided in the following sub-paragraphs:
