Page 7: Standard Module
Distributed by www.texim‐europe.com 2.2 Standard Module The standard version of the OK202-25 allows for user configuration of three common communication protocols. First, the unit can communicate using serial protocol at either RS323 or TTL voltage levels. Second, it can communicate using the Inter-Integrated Circuit connect, or I C protocol. -
Page 8: I 2 C Connections
C protocol setting. This is best accomplished using a breadboard and the Breadboard Cable. Power must be supplied from your breadboard or another external source. To dive right into your application and use the OK202-25 in I mode, get started with the guidelines below. -

Figure 14: Dallas One-Wire Connector In addition to the six general purpose outputs the OK202-25 offers an Optional Dallas One-Wire bridge, to allow for an additional thirty two one-wire devices to be connected to the display. This header can be populated with a Tyco 173979 connector at an added cost by custom order only. -
Page 16: Keypad Header
Row 5 Gnd/Vcc* To facilitate user input, the OK202-25 provides a Keypad Interface Connector which allows a matrix style keypad of up to twenty-five keys to be directly connected to the display module. Key presses are generated when a short is detected between a row and a column. When a key press is generated, a character specific to that key press is automatically sent on the Tx communication line. -
