0V
Ground
P0/PGM Parallel channel True logic (0V = low). Weak pullup to 3V;
select LSB, bit 0 Serial frequency programming / configuration¹
P1
Parallel channel True logic (0V = low). Weak pullup to 3V
select, bit 1
P2
Parallel channel True logic (0V = low). Weak pullup to 3V
select, bit 2
P3
Parallel channel True logic (0V = low). Weak pullup to 3V
select, bit 3
P4
Parallel channel Jumper inserted, P4=0 (Channel 00 – Channel 15 at 50kHz step)
Jumper select MSB, bit 4 Jumper clear, P4=1 (Channel 16 – Channel 31 at 50kHz step)
Notes:
1. Serial programming is by an inverted, CMOS logic level, 2400 baud RS232 datastream applied to
the P0 pin.
2. Parallel channel select is by 4 pin parallel input (LSB selected by a 2mm header, accessed through
a hole in the can)
3. Channel select inputs have pullups (10K) to 3V internal rail. Do not exceed 3V logic levels on this
port.
4. Transmitter will shutdown if Vcc falls below about 2.9v
5. TXD: logic low < 1.3V, logic high > 1.7V. TXD maximum voltage = 10V
