Function Switch: SW503 SW503 determines some of the basic operating parameters of the E5ZD, as
shown in the following table. These settings are described below. Switch ap-
pearance and pin number are the same as SW502, shown above. All pins are
set to OFF at the factory.
SW503 ON OFF
Pin Function ON OFF
1 Operation mode Test Normal
2 Memory bank designation Inputs Communications
3 Unit of measure Fahrenheit Celsius
4 Initial status Operating Non-operating
Pin 1
Pin 1 determines whether the normal operation mode or the communications
test mode (the mode in which the loop-back test is executed) is to be used. If pin
1 is set to ON and then power is applied to the E5ZD, the communications test
mode will be used and the following character string will be sent continuously
until the power is cut. Reception should be confirmed at the host computer. A
loop-back test will be conducted simultaneously to see whether the E5ZD can
receive the transmitted data back again. If it cannot receive the data back just as
it was transmitted, a Temperature Controller alarm output will turn ON.

Pin 2
Pin 2 determines whether the current memory bank is to be set according to in-
put status or via communications from the host computer. If pin 2 is set to ON
before power is turned ON, the status of the BANK0, BANK1, BANK2, and ING
terminals will determine the current memory bank. If pin 2 is OFF, the current
memory bank will be determined according to commands sent from the host
computer.
Pin 3
Pin 3 determines whether Fahrenheit or Celsius is to be used. (Fahrenheit and
Celsius can be manually converted via this equation:

F = 1.8
