Chapter 5: Connecting
IR/SERIAL
This type of port provides:
• Output for infra-red emitters (IR Adapters); the maximum IR output rate is 1.2 MHz.
• For RS-232 serial output (one way), the maximum serial data rate is 115 200 Bd (bps), and output signal levels
for RS-232 are in the -12 V to +12 V range.
The IR outputs and RS-232 outputs can be combined on independent outputs (for example, three outputs can be used as IR,
and five outputs can be used as RS-232).

NOTES:
• All pins labelled G are connected together.
• Up to three original infra-red emitters (IR Adapters) can be connected to each output in parallel
• We do not recommend connecting more infra-red emitters from various manufacturers in parallel, because the output can
be either overloaded or damaged.
