Chapter 4: Appendix D - |
Switch positions 5 and 6 on switch blocks S1, S2, S3, and S4 allow the "receiver stations" (RxD and CTS) to have either a DC load of 150 ohms or an AC load of 150 ohms in series with a 50 nF capacitor. Please refer to the examples following for these configuration options and their switch settings.
Examples:
1.The following example shows the switch settings for Station A as per Figure 17 where TxD and RTS have a load of 150 Ω.
switch blocks S1, S2, S3, or S4
2.The following example shows the switch settings for Station B and Station C as per Figure 17.
switch blocks S1, S2, S3, or S4
3.The following example shows the switch settings for Station D as per Figure 17 where RxD and CTS have a DC load of 150 Ω..
switch blocks S1, S2, S3, or S4
4.The following example shows the switch settings for Station D as per Figure 17 where the circuit is > than 50 metres in length and RxD and CTS have an AC load of 150 Ω in series with 50 nF.
