Switches 1 and 2: Transmit Clock
Switches 1 and 2 are used together to specify the clocking method. The Model 1025 can provide an internal clock (Pin 15), receive an external clock (from Pin 24), or loopback a received clock.
Switch 1 | Switch 2 | Setting |
On | On | External Clock |
On | Off | External Clock |
Off | On | Internal Clock (Default) |
Off | Off | Receive Loopback |
Switch 3: RTS/CTS Delay
After request to send (RTS) is raised by the host terminal, the
Model 1025 raises CTS after a delay in order to give the remote termi- nal time to receive an incoming signal. Depending on the type of envi- ronment, either a 7mS or 53mS delay can be selected.
Switch 3 | Setting |
On | 7 mS (Default) |
Off | 53 mS |
Switches 4, 5 and 6: Data Rate
Switches 4 thru 6 are set in combination to allow the Model 1025 to be used at data rates from 1.2 to 19.2 Kbps.
