(connected locally to the M&C computer): 1200, 2400, 4800, 9600, 19K2 (19200), or 38K4
(38400) baud are available.
You must be in Local mode to set the asynchronous character format: Use the [←][→] arrow
keys to navigate to the format setting. Then, use the [↑][↓] arrow keys to select the
asynchronous character format as: 8N1 (8 data bits, no parity, 1 stop bit); 7O2 (7 data bits, odd
parity, 2 stop bits); or 7E2 (7 data bits, even parity, 2 stop bits).
Press [ENT] when done.

5.2.1.4 Config: RefAdj (Reference Oscillator Adjustment)
UTIL Ref-Osc:
Adjust=087 (◄ ►▲▼ENT)
To adjust the reference oscillator: Use the [←][→] arrow keys to select a digit to edit, and then
the [↑][↓] arrow keys to change its value. Press [ENT] when done.
The default Reference Frequency tuning adjustment is 087, with allowable values from 0 to 255.
When an external reference oscillator is connected and set to 10 MHz the following screen
appears:
EXTERNAL 10 MHZ
REFERENCE PRESENT
When an external reference oscillator is connected and set to 5 MHz the following screen
appears:
EXTERNAL 5 MHZ
REFERENCE PRESENT
When an external reference oscillator is connected and set to other than 5 MHz or 10 MHz the
following screen appears:
EXTERNAL REFERENCE FREQ
MUST BE 5/10 MHz
