The standard version of the GLK240128-25/GLT240128 allows for user configuration of three common
communication protocols. First, the unit can communicate using flow controlled serial protocol at either
RS323 or TTL voltage levels. Second, it can communicate using the Inter-Integrated Circuit connect, or
I
header as outlined in the Serial Connections and I

Serial Connections
Serial protocol provides a classic connection to the GLK240128-25/GLT240128. The Extended
Communication/Power Cable is most commonly used for this set up as it provides connections for DB9
serial and floppy power cables. To place your board in Serial mode, adhere to the steps laid out below.
1. Set the Protocol Select jumpers.

*Note:
RS232: Connect the five jumpers in the 232
provided or an alternate wire or solder solution.
TTL: Connect the four jumpers in the TTL
Cable (ESCCPC5V)
Jumpers must be removed from all protocol boxes save for the one in use.
The most common cable choice for the GLK240128/GLT240128, The
Extended Communication and Power cable offers a simple connection
to the unit with familiar interfaces. A DB9 and floppy power header
provide all necessary input to drive your display.
For a more flexible interface to the GLK240128-25/GLT240128, a
Breadboard Cable may be used. This provides a simple six wire
connection that is popular among developers for its ease of use in a
breadboard environment.
