Setting the Frequency Mode, Programmable Pulse B
The frequency mode is available with Programmable Pulse B, not Programmable Pulse A. To use
the frequency mode, you must select Programmable Pulse B from the main menus. The frequency
mode broadcasts a square wave (at 50% duty cycle) from Output 3 and/or Output 4 at a rate of
1 to 1000 pulses per second. See Figure 7.18.

Setting the Aux IRIG Mode, Programmable Pulse B
The Model 1094B allows you to set up two different forms of the unmodulated IRIG-B time code.
For example, one group of relays may require UTC time, and others may require the Local time.
Also, this feature allows you to set up one output with the IEEE 1344 ON and OFF for the others.
To use the Aux IRIG Mode, you must select Programmable Pulse B from the main menu, and set
internal jumpers for Output 3 and/or Output 4. See Figure 7.19.
Figure 7.19: Programmable Pulse Setup, Aux IRIG-B Mode
Before configuring this option, please make sure to read over how to configure the internal
jumpers for Programmable Pulse B mode. Also, determine which port or connector you would like
to use. The Model 1094B allows setting up Programmable Pulse B from Timing Output 3 and/or
4 and also COM2, RS-485 only. If you would like to use Timing Outputs 3 and/or 4, please turn
to Section 5.2, and if you wish to use COM2, please turn to Section 5.4.
