6. Hardware Information

6.1 Auxiliary Channel Configuration

An auxiliary channel is provided which allows for handshaking between the

SSP-200/300 port and a peripheral device. This auxiliary channel may be configured in

one of two ways:

v RTS-CTS handshake enabled.

v handshaking is disabled.

6.1.1 Auxiliary Channel: RTS-CTS Handshaking.

The RTS-CTS handshake may be enabled so that RTS (request to send) is the auxiliary

output signal on AUX OUT+ (pin 1) and AUX OUT- (pin 6). Similarly, CTS (clear to

send) is the auxiliary input signal on AUX IN+ (pin 5) and AUX IN- (pin 9). This

configuration is shown below.
