All TTL signals are 3.3 V TTL signals which are 5 V tolerant,
so they can be connected to 5 V TTL systems.
For instruments with serial number 14266 and higher, pins 9,
11, 12, 13 are open collector outputs. Connect a pull-up resistor
of 1 kOhm to pin 5 when using one of these signals. For older
instruments, the outputs are standard TTL outputs and no pull-
up is required.
