Setup and Addressing of the Com Module
Last TRNR Cmd
(Radio Only): Not in ACC-P2P-LTE models, displays the
characters in the last-received UHF Maintenance Radio command, for
diagnostic purposes. This setting is not shown if there is no radio. This
setting only applies to UHF Maintenance Radio and will not show ICR
remote commands.
DTMF Processing:
Enables DTMF decoding, which allows Maintenance
Radio remote control to operate. Press Enter and use +/- buttons to disable
if DTMF is not desired.
Radio Channel Switch:
Allows selection of pre-programmed radio channels
1-16. Press Enter, use +/- to manually override the DIP switch settings in the
radio, and use a different channel. User must be licensed to transmit on a
specific channel.
MR Default Run Time
(Radio Only, not shown in ACC-P2P-LTE models):
Default = 30 Minutes. This sets the automatic run time for any station or
SSG that is started by a Maintenance Radio command, if no run time has
been specified in the On command. It is possible to turn a station or SSG on
without specifying a run time, and this setting will automatically them off
after the specified time if they are not turned off by an Off command. The
Default Run Time can be changed in 1-minute increments up to a maximum
of 60 minutes. This setting is not shown if there is no radio and does not
affect ICR remote commands.
HWIM
(not shown in ACC-P2P-LTE models): Indicates presence of a
Hardwire Interface Module (ACC-HWIM) installed in the controller. “None”
indicates no HWIM has been found, “Installed” indicates that the HWIM is
installed and has been detected. This display is informational and cannot be
changed from the Com module.
Enter Diagnostics:
To use the built-in communications diagnostics, press the
Enter button at this display.
This will allow you to select from the following diagnostic functions (use the
up or down arrow buttons to move through the choices).
Communications Status Display [MOD RAD HW]:
Pressing the left arrow
button at any time will show a status display for communications, showing
transmit and receive activity for each communications type. The display
shows: MOD RAD HW #, indicating Modem, Radio, Hardwire, and number of
data packets sent.
Under each item MOD, RAD, and HW, the letter T shows transmit activity
and R shows receiving data for that communications component. The
symbol * shows other radio traffic (“carrier detect”). This is a useful
diagnostic tool.
MOD:
Shows cellular modem activity.
RAD:
Shows T when the controller radio is transmitting, and R when it is
receiving data from another radio.
HW:
Shows T when the controller is transmitting over GCBL cable, and R
when receiving data via GCBL.
#:
Shows the count of individual packets of data as they are exchanged. This
number continues to increase as events are counted until it reaches 255, and
then begins again at 1.
Digital communications are divided into packets of data, and sent in
pieces called “packets.” After each packet is sent, a confirming response is
expected. This counter tracks all communications in the module via radio,
hardwire, and modem.
The * may indicate other radio traffic (from other sources). Communications
problems that cannot be explained by hardware issues are sometimes
caused by interference from other sources. If * is frequently present when no
ACC communications are taking place, it may indicate that the frequency is
very busy.
Radio Tone Test
(not shown in ACC-P2P-LTE models): The radio test is only
active when a UHF radio module is installed. Press the left arrow button
twice to display the Radio Tone Test, and press Enter to start the test. The
radio module will transmit a 5-second burst of data to confirm whether the
radio is working. The burst can be heard with another radio or scanner tuned
to the same frequency.
For this test to be effective, you will need a two-way radio or scanner on the
same frequency as the radio module.
When the radio test is started, a burst of data indicates a working radio
module in the controller.
If nothing is heard, either the radio is inoperative or the wrong frequency has
been selected for receiving.
