2.3 GPO
A unique feature of the GLK12232-25 is the ability to control
relays and other external devices using a
General Purpose Output (3), which can provide up to 20 mA of current and +5Vdc from the positive side of
the GPO. This is limited by a 240 ohm resistor which is located
directly above the positive pin as pictured
below in
?gure 14
. If the device, which is being driven by a GPO, requires a relatively high current (such as
a relay) and has an internal resistance of its own greater than 250 ohms, then the 240 ohm resistor may be
removed and replaced with a Jumper.

Pin

+ MAX: 20 mA, +5Vdc

WARNING
If connecting a relay, be sure that it is fully clamped using
a diode and capacitor in order to absorb any electro-motive force (EMF)
which will be generated.
2.4 Protocol Select Jumpers
The
Protocol Select Jumpers, pictured below in
?gure 15
, provide the means necessary to toggle the
display module between RS-232, TTL and I2C protocols. As a default, the jumpers are set to RS-232 mode
with zero ohm resistors on the 232 jumpers. In order to place the display module in I2C mode you must
?rst remove the zero ohm resistors from the 232 jumpers and th
en solder the resistors on to the I2C jumpers.
The display will now be in I2C mode and have a default slave address of 0x50 unless it has been changed.
Similarly, in order to change the display to TTL mode, simply
remove the zero ohm resistors from the 232
or I2C jumpers and solder them to the TTL jumpers.
