(9) 1 PPS Enable/Delay
This mode allows the master to propagate a 1PPS signal to all the remotes in a multipoint network. The properly
generated pulse applied on the DTR line of the master will provide a 1 PPS pulse on the CD line of any remote in the
system. The output on the Slave will occur within 20 microseconds of the input to the Master.
•0 in the master to enable 1 PPS pulse mode.
The master must have a 1 PPS pulse on the DTR line.
•0 – 254 Set to adjust the timing out the CD line of the remote unit.
When properly calibrated the CD line of a Slave radio will output a pulse that goes high for about
2mS in synch with the 1 PPS pulse on the Master radio.
•255 to disable 1 PPS pulse mode.
Note: If 1 PPS is set to 1, the Master must have a 1 PPS pulse on its DTR pin, otherwise the RF network will not
function.
(A) Slave/Repeater for the SRM model
(8) Slave/Repeater for the PLR model
Set this mode to allow a repeater to act as a remote and a repeater. In this mode data will be re-transmitted over the RF
as well as sent out the local data port.
•0 to disable the data port on a repeater.
•1 to enable the data port on a repeater.
Note: This option is only used if the radio is in mode (7) MultiPoint Repeater.
Note: Options in Blue are SRM models only
(B) Diagnostics – (Not Available on the Wireless I/O Extender)
This option is to view diagnostics data at the master radio in parallel with application data.
•0 to disable diagnostics.
•1 thru 128 Set to enable serial diagnostics.
•129 for UDP diagnostics.
Note: The diagnostic program must be connected to the master radio using the secondary optional diagnostics
port.
Note: A Windows© computer with a serial port or UDP connection (Ethernet models only) running the diagnostics
software is needed.
(C) SubNet ID for the SRM model
(9) SubNet ID for the PLR model
This option is to to direct the RF path of a system. These are the sub-channels that repeaters use to differentiate the RF
links. The Subnet ID option is particularly helpful to force two repeaters in the same system to operate in series rather
than in parallel, or if desired, to force the remote to communicate to a specic repeater for load balancing purposes.
The Subnet ID option consists of the receive (Rcv) channel and the transmit (Xmit) channel.
•The receive (Rcv) Subnet ID identies which channel a repeater or remote will listen to.
•The transmite (Xmit) Subnet ID identies which channel a repeater will transmits, and in turn which devices will listen to
it.
