C.2.20 “ATS62” Set System/Log Timer
S-register 62 sets the log timer. The log timer is the millisecond value displayed next to each output log.
ATS62=100<CR>
: Sets the log timer to 100ms.
C.2.21 “ATS70” Set Port Protocol Type
S-register 70 sets the protocol mode for the serial port. The only valid values are:
ATS70=0<CR>
: Disables the serial port.
ATS70=1<CR>
: Sets the serial port into point-to-point mode. See section 4.3.1 for information on
point-to-point networks.
ATS70=2<CR>
: Sets the serial port into point-to-multipoint broadcast mode. See section 4.3.2 for
information on point-to-multipoint broadcast networks.
ATS70=3<CR>
: Sets the serial port into Hayes dial-up mode. See section 4.3.3 for information on
Hayes dial-up networks.
C.2.22 “ATS80” Local Auxiliary I/O Hex data
S-register 80 contains the current value being read from the auxiliary I/O input as an 8-bit number, where a
bit is set to 1 for a logic high and 0 for logic low. It can also be used to set the local outputs.
ATS80=F0<CR>
: Sets the Auxiliary I/O bits 0…3 to output 1 and bits 4…7 to output 0.
C.2.23 “ATS81” Get Remote Auxiliary I/O Hex data
S-register 81 is a read-only register that contains the current value being read from the remote auxiliary I/O
input as an 8-bit number, where a bit is set to 1 for a logic high and 0 for logic low.
C.2.24 “ATS82” Auxiliary I/O Direction Mask
S-register 82 contains the direction mask for the auxiliary I/O on the local radio. A bit set to 1 sets the I/O as
an output, and 0 sets the I/O as an input.
ATS82=00<CR>
: This would set all eight I/Os as inputs.
ATS82=F0<CR>
: This would set I/Os 0…3 to be inputs and I/Os 4…7 to be outputs.
C.2.25 “ATS83” Set Auxiliary I/O Power-up Default
S-register 83 contains the power-up default value for the auxiliary I/O port. A bit set to 1 sets the I/O as logic
high, and 0 sets the I/O as logic low.
ATS83=FF<CR>
: This would set all eight I/Os to logic high on power-up.
