Setting Communications

The [B]=COMMUNICATIONS function is used to enter data transmission speed and a terminal ID number. Use this function if the clock will be programmed to call the NIST atomic clock, or if you are using the optional Lathem MasterLink software to program the master clock. The clock can be set up using RS-232 (serial), RS-485 (networked), or modem (remote) com- munications. You must enter the same settings for the Model 24A715M in the programming software.

You can view the current terminal ID# and baud rate by using the quick command [*] when the master clock is in clock mode.
