terminals

6V BAT- Negative terminal of 6V backup battery. This terminal

is connected to system ground

Note: The battery voltage must be 6V. The battery should be either a

Sealed Lead Acid or a Gel Cell. The recommended minimum capacity

for the battery is 2.6 Ah. This is sufficient to provide back up power for

short power outages lasting a few minutes.

GND System ground.

RLY 1a, 1b User relay contacts enabled by software.

Note: Contact rating for these solid-state relays is max. current 130mA,

max. load voltage 300V

rms

, max. power dissipation 500mW. The tighter

of any restrictions applies. Typical ON-resistance is 25 static, 12 at

full load. These ratings apply to all relay contacts.

RLY 2a, 2b User relay contacts enabled by software.

RLY 3a, 3b User relay contacts enabled by software.

RLY 4a, 4b User relay contacts enabled by software.

INPUT 1, 2, 3, 4 Opto-coupled user definable trigger inputs, pull to

ground to activate (short to GND terminal).

BARCODE Enables signal input from Barcode Reading Device via

TRIGGER the serial connection. Pull to ground potential to

activate (short to GND terminal).

BARCODE TX Serial output to Barcode Reading Device.

BARCODE RX Serial input to Barcode Reading Device.

Note: Depending on top slide switch setting, the serial line for the bar

code ports will be compliant to either RS-232 or RS-485 standard.

These terminals can be used to connect other serial devices.

TEST TX Serial test output.

TEST RX Serial test input.

Note: The serial line for the test connection is always RS-232.
