RADIO SELF TEST
The Radio Self Test feature is used to test the radio
conductivity of a given geographical area without the use
of external hardware attached to the ESTeem
(i.e. terminal, computer, etc.) by performing a GO or NO
GO test by visually looking at the ESTeem T/E light. If
after resetting the ESTeem the T/E light changes from a
twice per second flash rate to solid ON light the radio
path has been tested. This test is usually done by
attaching a 12 VDC battery pack to the remote ESTeem
and walking a given area and pushing the reset switch to
test the radio path at various points of interest relative to
a fixed reference point. This test is used to give the user
a rough test of the radio operating range but does not
give signal strength, back ground noise levels, or sources
of co-channel interference.
To perform a radio self test requires two
ESTeems. Address 254 is a special address used for the
self-test feature and is assigned to the remote ESTeem.
After addressing the remote ESTeem to 254 it is then
programmed to auto connect to the reference ESTeem.
Address 254 is a special command that allows the
ESTeem to perform the AUTO CONNECT upon reset,
not when the unit senses data through it's RS-232C port.
When the remote ESTeem is reset by the front panel
switch it will initiate a CONNECT to the reference
ESTeem (T/E Light on solid) and send the message
TEST PACKET if the ESTeem is within radio range of
the reference ESTeem. It is noted that repeater address
strings can be assigned to the remote ESTeem SETC
address.
Perform the following prior to programming the
ESTeem(s) to initialize the units to factory default
settings:
1. Turn Bit 8 OFF on the RS-232C Setup Switch.
2. Reset the ESTeem.
3. TYPE FA <cr>. Please note the characters my not
be echoed by the crt.
