Console to M427 audio level adjustment
This procedure causes the console to output a tone so that the Tx gain at the MAP27
channel card can be adjusted to give the desired level at the M427 input. It assumes a
typical line length and sets the M427 input gain about midway up (28 out of 64). For very
long lines it may be necessary to increase the M427 input gain, but only if there is not
enough adjustment at the MAP27 channel card.
1. Connect the
COM1
serial port on the PC or laptop to the M427 front panel serial
port using a straight cable.
2. Start the Zetron utility program
M827Base
.
3. Click

order to select the

menu and navigate to the dialog that displays the input
level of a tone.
5. Set the M427 input slider level to
28
(for normal length lines).
6. The bar below the level slider will now display the level of the received audio, we
want this to end up reading
-10
.
7. Make a call from the console to a MAP27 radio that goes through the M427 and
then key up the 1 kHz alert tone (using a previously configured on screen button).
8. While observing the M427 level meter on the PC or laptop, at the S4000 MAP27
channel card adjust the
TX
level pot until the meter reads
-10
.
9. At the PC or laptop, terminate the test by closing the dialog box.
10. Close the
Levels
menu.
11. Click

DISCONNECT
.
12. Close the
M827Base
program.
This completes the Console to M427 audio level adjustment. The Tx level now set should
be such that a Tx sine wave alert tone causes a 60% radio channel deviation. This is the
same Tx level as the dual channel card audio level setup (see
Operation
Programming the Console
The Integrator Radio Dispatch Programming Software (RDPS) includes programming
selections for the type of MAP27 channel card, associated channel control buttons, and the
following entries:
• MAP27 radio groups
• Subscriber ID aliases (radio or group IDs)
