Modes of Operation
The ESTeem Model 195M, 195H and 195C can be configured for multiple serial and Ethernet applications. Determining the
correct mode of operation for the ESTeem is the first step in creating a reliable wireless network. This chapter will explain each
mode of operation, provide example applications and detailed programming information for each mode. Please review the
following modes of operations. If you do not see an example of your application, please contact ESTeem support at 509-735-
9092 for help in selecting your mode of operation.
Transparent Point to Point Application
The most commonly used mode of operation with the ESTeem Model 195M/H/C is the transparent mode. The transparent
mode will pass serial or Ethernet data between two (or more) wireless modems as if they were connected by a cable. Point to
point operation is when two serial or Ethernet devices are transferring information between either other, directly or through a
repeater (Figures 1 and 2). The type of serial data interface (RS-232, RS-422, RS-485 or Ethernet) on either end of the wireless
link is configurable and can be independent on each side. For example, the Main Office in Figure 1 can be configured for RS-
232 operation, while the serial port at the remote site can be configured for RS-485.
Example Applications
